When you see a context-relevant advertisement on a web page, it’s most likely content served by a Taboola data pipeline. As the leading content recommendation company in the world, a big challenge for Taboola was the frequent need to scale Apache Spark CPU cluster capacity to address the constantly growing compute and storage requirements.
Data center capacity and hardware costs are always under pressure.
What caused the scaling challenges? Taboola uses a complex data pipeline stretching from user browsers or mobile devices through multiple data centers. Complex deep learning algorithms, databases, infrastructure services (such as Apache Kafka), and thousands of servers are deployed to serve the best-fitting ads to users around the world.
This post describes Taboola’s motivation to move to RAPIDS Accelerator for Apache Spark to optimize processing costs, along with insights on the migration process, challenges, and lessons learned to date.
Challenges of feeding a compute-hungry pipeline
To plan solutions, you must fully understand the magnitude of the problem. When serving ad content, Taboola builds a unique pageview that identifies each user and their interaction with the system. The pageview, a large, wide data structure, is built within a massive CPU cluster using data collected across worldwide data centers. The structure contains over 1500 distinct columns amounting to >1 TB of hourly data, all processed in our Apache Spark CPU cluster.
Many distinct analyzers and SQL queries process incoming pageviews at a rate of 1 TB of raw data per hour and catchup runs at 2, 6, 12, and 48 hours. New analyzers are constantly being created that increase the load on the Apache Spark cluster. There is a growing need for more compute power.
Our main task was to make the complex compute-hungry pipeline more scalable while being cost-effective. To address this challenge, Taboola embarked on an effort to migrate thousands of CPU cores to GPUs, to help us cope with the increasing data load to be processed.
One tool we considered to accelerate Taboola’s Apache Spark environments was the RAPIDS Accelerator on GPUs. As such, it was a natural decision to attempt greater scalability on GPUs as opposed to CPUs.
First, we defined what we needed for testing to successfully migrate thousands of CPU cores to leverage GPU acceleration:
- Real-life dataset
- Hardware specifications
- Minimum X factor
- Complex query testing
We used real production data from Cyber Monday to test and benchmark a large dataset. The data is 1.5 TB of ZSTD-compressed Parquet files per hour. It has over 1500 columns of all native types including arrays, structures, and nested structures with arrays.
For hardware, we started with the following resources:
- A 72 CPU core Intel server with three A30 GPUs
- A 900-GB local SSD drive, for Apache Spark to store its intermediate files
- 380 GB RAM
- A 10-Gb/s NIC card
Minimum X factor
The primary question when migrating a project from the CPU to the GPU is usually, “What’s the X factor?” For a real-world cluster with multiple GPUs, the question is, “How many GPUs do I need for sustaining a load manageable by X CPU cores?” The answer is your X factor.
We set a minimum bar of an X factor of 3 for the GPU solution to be considered successful in terms of cost. This factor helps guarantee our migration efforts will pay off.
Complex query testing
We picked 15 queries from production across multiple R&D departments to resemble as many of the hundreds of queries as are in production.
The queries are mostly complex including many SQL operations:
- Lateral view explode
- Distribute by
- Window functions
Figure 1 shows an example query.
Table 1 shows you Taboola’s factors.
|Analyzer name||Avg CPU production time||Avg GPU time||GPU factor|
CPU-to-GPU migration goals
We began with a single server (as described earlier) capable of scaling to a multi-GPU and multi-server cluster. The cluster would be managed by Kubernetes, as opposed to the current Mesos cluster. Mesos was going to become obsolete and NVIDIA environments support Kubernetes.
Any changes in the software and hardware environment would have to be oblivious to Taboola’s code. Queries run on GPUs should execute with the exact results as CPUs. The team was aware of this challenge, as production stability was a critical goal.
Lastly, we wanted the GPU to outperform the CPUs by a minimum factor of 3. We benchmarked several GPUs including NVIDIA P100, NVIDIA V100, NVIDIA A100, and NVIDIA A30. We learned that the A30 GPU gave us the best price-performance fit.
First experiment with RAPIDS Accelerator
We ran SQL queries using RAPIDS Accelerator with somewhat disappointing results. Some of the less complex queries, mostly with lateral view explode, gave a 3x to 5x factor over the CPU. Some showed much lower factors, while other queries crashed.
After asking questions in the RAPIDS GitHub repo, we tried relevant Apache Spark and RAPIDS Accelerator parameters and began seeing better results:
sql.files.maxPartitionBytes: The CPU uses a default value of 128 MB. This is too low for the GPU. We are using 1–2 GB.
sql.shuffle.partitions: We found the 200 default to be sufficient in most cases.
rapids.sql.concurrentGpuTasks: Determines the number of tasks that can be run concurrently on the GPU. A minimum of at least two tasks appears to be best.
Tuning these parameters helped the queries run more smoothly and perform better in some cases. The NVIDIA Accelerated Spark Analysis tool can automatically generate tuning recommendations.
Challenge #1 – Parquet parsing overhead
We experienced bottlenecks on some of the less performant SQL queries, with most of them wasting time parsing Parquet footer data on the CPU. The Parquet data has more than 1500 columns. It was apparent that regular Java code for parsing the footer was not adequate for such a large footer.
Figure 2 shows a small section of NVIDIA profiler output for a 9-second Apache Spark task where the GPU was mostly idle (only working for 330 ms).
Figure 3 shows a flame graph of a query suffering from this behavior. The purple bars indicate time spent inside the
org.apache.parquet.hadoop.ParquetFileReader class. Almost 50% of the query time was spent on parsing Parquet’s footer while the GPU was idle.
As such, we set off to test an alternative solution. When parsing the footer, Parquet code would iterate over footer metadata serially for each row group. We adjusted Parquet parameters to decrease the number of row groups in each file. This gave us about 10–15% improvement. We found this improvement to be insufficient.
Each time metadata was read, all 1500 columns of metadata were read and parsed serially, even after only asking for 50-100 columns per query. We wanted to index footer metadata such that instead of reading the entire 1500 data columns serially, we’d just access it directly. We managed to make this happen by changing the
Parquet-mr public code in C++ and Java. Although we got nice performance results, this was too cumbersome and complex.
Fortunately, the NVIDIA RAPIDS team had a much better idea. The solution was optimal Parquet file parsing. They replaced the Java code with Arrow’s C++ implementation. We now have the
rapids.sql.format.parquet.reader.footer.type set to NATIVE by default for our GPU implementation. The bottleneck was solved and there were no longer queries with the GPU idle because of footer parsing overheads on the CPU.
Challenge #2 – Network bottleneck
A weak network card caused the next bottleneck. While the 10-Gb/s Ethernet card sustained the CPU load, it failed to do so for the GPU load.
The solution was an optimal network card for GPU loads. Replacing the 10-Gb/s Ethernet card with a 25-Gb/s card removed this bottleneck.
Challenge #3 – Disk I/O bottleneck
Even after removing the two bottlenecks, queries still ran slow. On the Apache Spark user interface, we saw a clear indication as to what was happening.
|Metric||Min||25th percentile||Median||75th percentile||Max|
|Duration||0.4 s||0.6 s||0.8 s||1 s||1.2 min|
|GC Time||0.0 ms||0.0 ms||0.0 ms||90.0 ms||0.5 s|
|Shuffle Read Size/Records||21.4 MB/1000||22.3 MB/1000||22.5 MB/1000||22.7 MB/1000||27.3 MB/1000|
|Shuffle Write Size/Records||17.5 MB/1000||17.9 MB/1000||18 MB/1000||18.1 MB/1000||18.1 MB/1000|
|Scheduler Delay||3.0 ms||5.0 ms||5.0 ms||7.0 ms||3 s|
|Peak Execution Memory||64 MB||64 MB||64 MB||64 MB||64 MB|
|Shuffle Write Time||9.0 ms||13.0 ms||18.0 ms||21.0 ms||59 s|
In Table 2, in the Max column, the task’s duration is 1.2 minutes, while Shuffle Write Time took 58 seconds. A lot of time was wasted doing shuffle work while the GPU was idle.
Figures 4 and 5 show the appropriate event timeline graph. The orange part represents shuffle times, read or write. The green parts are compute time. We were wasting a lot of time reading or writing shuffle files.
Our shuffle files can get up to 500 GB and greater in some queries. We obviously can’t keep this huge amount of data in the server’s RAM, so shuffle files are stored in the local SSD drive.
After a quick investigation with our teams, we figured out that the SSD drive was configured to use RAID-1. Each temporary shuffle file was saved twice to the disk. This wasted a lot of time and switching to RAID-0 somewhat improved the situation.
The GPU put more pressure on the SSD drive than the CPU such that we had to replace the SSD with an NVMe drive. The solution was to switch to a 6-TB NVMe drive. We removed one of the GPUs to create a slot for the NVMe drive. Afterward, we had no shuffle read or write performance issues. We also learned that one NVMe drive could sustain the workload of two A30 GPUs.
Moving to Kubernetes
Because our Mesos cluster would become obsolete, the move to Kubernetes from a standalone POC machine was imperative. This involved a lot of configuration work, and other minor work. Still, it was straightforward to implement.
The basic idea is that the Apache Spark driver would sit on a non-GPU machine and each K8s Pod would be associated with a single GPU. For more information, see Getting Started with RAPIDS and Kubernetes.
The following code example shows some of the major relevant Kubernetes configurations.
spring: profiles: include: spark_k8s_extra_files spark: driver: sparkConnector: sparkOpts: spark.kubernetes.container.image.pullPolicy: Always spark.kubernetes.authenticate.serviceAccountName: spark spark.kubernetes.executor.deleteOnTermination: true spark.deploy.mode: client spark.executorEnv.preLoadMemoryLibraryName: "/usr/libjemalloc.so" spark.executorEnv.xmxPercentage: 80 spark.kubernetes.memoryOverheadFactor: 0.1 spark.mesos.fetcherCache.enable: false spark.executor.extraJavaOptions: -XX:-UsePerfData -XX:-OmitStackTraceInFastThrow -verbose:gc -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+PrintFlagsFinal -Dmapreduce.fileoutputcommitter.algorithm.version=2 -XX:NativeMemoryTracking=detail spark.plugins: "com.nvidia.spark.SQLPlugin" spark.kubernetes.executor.podTemplateFile: /conf/k8GPUPodTemplateProduction.yml spark.executor.resource.gpu.vendor: "nvidia.com" spark.executor.resource.gpu.discoveryScript: /conf/getGpusResources.sh spark.executor.resource.gpu.amount: 1 # GPU task configuration spark.rapids.sql.variableFloatAgg.enabled: "true" spark.rapids.sql.castFloatToDecimal.enabled: "true" spark.rapids.sql.rowBasedUDF.enabled: "true" spark.rapids.sql.format.parquet.reader.footer.type: "NATIVE" spark.rapids.sql.explain: "all" # For debug. # Most common spark.rapids.sql.concurrentGpuTasks: 4 spark.sql.files.maxPartitionBytes: "2048m" spark.rapids.sql.batchSizeBytes: "1g" spark.sql.shuffle.partitions: 200
How many GPUs to accelerate?
If the goal is to use GPUs to accelerate workloads more cost-effectively than CPUs, we first had to understand how fast GPUs were. We set up a test system with two A30 GPUs and streamed production data to it in parallel with our large CPU core production environment.
Figure 6 shows two of our heaviest queries running on the production CPU cluster and also on the server with two A30 GPUs.
The yellow and green lines denote the hourly total time across all task numbers of the two queries running on the CPU cluster. The blue and orange lines denote the same queries running on the GPU server. GPU factors are 20x and higher.
Figure 7 shows the two queries running on the GPU shown in Figure 6. Observe that they behave similarly to the CPU in that peaks and valleys roughly align at different times of the day.
Figure 8 is interesting in that it shows the factor of all the queries that we migrated to the GPU and their counterparts on the CPU. The GPU run is missing the biggest query, which we are still working on migrating to the GPU. It will likely add 200 hours per day to the GPU total time.
Looking ahead to our next migration steps, Taboola would like to move queries from other R&D departments to the GPU, resulting in a greater number of GPUs in production. This means that QA must monitor the system more closely while in production.
Getting acquainted with RAPIDS Accelerator for Apache Spark was an amazing “joy ride” effort. From handling Parquet files to pushing GPUs to their limit, we became better equipped at handling a large data pipeline along with managing data center capacity and hardware costs. Identifying and coping with hardware limitations with this method proved to be rewarding.
Here are Taboola’s top takeaways for those considering CPU-to-GPU migration:
- Tuning parameters in complex environments that have multiple variables is never straightforward. Automate this task to whatever degree possible. It’s probably a good idea to use the NVIDIA Accelerated Spark Analysis tool to help address this challenge, as it can easily suggest optimized parameters.
- Look beyond CPUs and GPUs for solutions to bottlenecks. No amount of GPU horsepower can resolve issues that are fundamentally network, disk, bandwidth, or configuration and parsing related.
- Multiple GPUs do not hinder performance, but GPUs are so powerful that you may have good performance with fewer GPUs than originally thought. It’s best to test for this to lower costs.
- We achieved our 20x factor through RAPIDS Accelerator and NVIDIA GPUs. The biggest lesson learned was that we needed to better understand what was happening in our existing environment before benefiting from GPU acceleration. One A30 GPU sustained the same production load for some workloads as the ~200-CPU core test cluster.
For more information about achieving performance multiples over Apache Spark CPU-based environments, see GPU-Accelerated Apache Spark.
Our huge effort was more successful with the support, assistance, and patience of two great groups of people.

Rapid digital transformation has led to an explosion of sensitive data being generated across the enterprise. That data has to be stored and processed in data…
Rapid digital transformation has led to an explosion of sensitive data being generated across the enterprise. That data has to be stored and processed in data centers on-premises, in the cloud, or at the edge. Examples of activities that generate sensitive and personally identifiable information (PII) include credit card transactions, medical imaging or other diagnostic tests, insurance claims, and loan applications.
This wealth of data presents an opportunity for enterprises to extract actionable insights, unlock new revenue streams, and improve the customer experience. Harnessing the power of AI enables a competitive edge in today’s data-driven business landscape.
However, the complex and evolving nature of global data protection and privacy laws can pose significant barriers to organizations seeking to derive value from AI:
- General Data Protection Regulation (GDPR) in Europe
- Health Insurance Portability and Accountability Act (HIPAA) and Gramm-Leach-Bliley Act (GLBA) in the United States
Customers in healthcare, financial services, and the public sector must adhere to a multitude of regulatory frameworks and also risk incurring severe financial losses associated with data breaches.
In addition to data, the AI models themselves are valuable intellectual property (IP). They are the result of significant resources invested by the model owners in building, training, and optimizing. When not adequately protected in use, AI models face the risk of exposing sensitive customer data, being manipulated, or being reverse-engineered. This can lead to incorrect results, loss of intellectual property, erosion of customer trust, and potential legal repercussions.
Data and AI IP are typically safeguarded through encryption and secure protocols when at rest (storage) or in transit over a network (transmission). But during use, such as when they are processed and executed, they become vulnerable to potential breaches due to unauthorized access or runtime attacks.
Preventing unauthorized access and data breaches
Confidential computing addresses this gap of protecting data and applications in use by performing computations within a secure and isolated environment within a computer’s processor, also known as a trusted execution environment (TEE).
The TEE acts like a locked box that safeguards the data and code within the processor from unauthorized access or tampering and proves that no one can view or manipulate it. This provides an added layer of security for organizations that must process sensitive data or IP.
The TEE blocks access to the data and code, from the hypervisor, host OS, infrastructure owners such as cloud providers, or anyone with physical access to the servers. Confidential computing reduces the surface area of attacks from internal and external threats. It secures data and IP at the lowest layer of the computing stack and provides the technical assurance that the hardware and the firmware used for computing are trustworthy.
Today’s CPU-only confidential computing solutions are not sufficient for AI workloads that demand acceleration for faster time-to-solution, better user experience, and real-time response times. Extending the TEE of CPUs to NVIDIA GPUs can significantly enhance the performance of confidential computing for AI, enabling faster and more efficient processing of sensitive data while maintaining strong security measures.
Secure AI on NVIDIA H100
Confidential computing is a built-in hardware-based security feature introduced in the NVIDIA H100 Tensor Core GPU that enables customers in regulated industries like healthcare, finance, and the public sector to protect the confidentiality and integrity of sensitive data and AI models in use.
With security from the lowest level of the computing stack down to the GPU architecture itself, you can build and deploy AI applications using NVIDIA H100 GPUs on-premises, in the cloud, or at the edge. No unauthorized entities can view or modify the data and AI application during execution. This protects both sensitive customer data and AI intellectual property.
For a quick overview of the confidential computing feature in NVIDIA H100, see the following video.
Unlocking secure AI: Use cases empowered by confidential computing on NVIDIA H100
Accelerated confidential computing with NVIDIA H100 GPUs offers enterprises a solution that is performant, versatile, scalable, and secure for AI workloads. It unlocks new possibilities to innovate with AI while maintaining security, privacy, and regulatory compliance.
- Confidential AI training
- Confidential AI inference
- AI IP protection for ISVs and enterprises
- Confidential federated learning
Confidential AI training
In industries like healthcare, financial services, and the public sector, the data used for AI model training is sensitive and regulated. This includes PII, personal health information (PHI), and confidential proprietary data, all of which must be protected from unauthorized internal or external access during the training process.
With confidential computing on NVIDIA H100 GPUs, you get the computational power required to accelerate the time to train and the technical assurance that the confidentiality and integrity of your data and AI models are protected.
For AI training workloads done on-premises within your data center, confidential computing can protect the training data and AI models from viewing or modification by malicious insiders or any inter-organizational unauthorized personnel. When you are training AI models in a hosted or shared infrastructure like the public cloud, access to the data and AI models is blocked from the host OS and hypervisor. This includes server administrators who typically have access to the physical servers managed by the platform provider.
Confidential AI inference
When trained, AI models are integrated within enterprise or end-user applications and deployed on production IT systems—on-premises, in the cloud, or at the edge—to infer things about new user data.
End-user inputs provided to the deployed AI model can often be private or confidential information, which must be protected for privacy or regulatory compliance reasons and to prevent any data leaks or breaches.
The AI models themselves are valuable IP developed by the owner of the AI-enabled products or services. They are at risk of being viewed, modified, or stolen during inference computations, resulting in incorrect results and loss of business value.
Deploying AI-enabled applications on NVIDIA H100 GPUs with confidential computing provides the technical assurance that both the customer input data and AI models are protected from being viewed or modified during inference. This provides an added layer of trust for end users to adopt and use the AI-enabled service and also assures enterprises that their valuable AI models are protected during use.
AI IP protection for ISVs and enterprises
Independent software vendors (ISVs) invest heavily in developing proprietary AI models for a variety of application-specific or industry-specific use cases. Examples include fraud detection and risk management in financial services or disease diagnosis and personalized treatment planning in healthcare.
ISVs must protect their IP from tampering or stealing when it is deployed in customer data centers on-premises, in remote locations at the edge, or within a customer’s public cloud tenancy. In addition, customers need the assurance that the data they provide as input to the ISV application cannot be viewed or tampered with during use.
Confidential computing on NVIDIA H100 GPUs enables ISVs to scale customer deployments from cloud to edge while protecting their valuable IP from unauthorized access or modifications, even from someone with physical access to the deployment infrastructure. ISVs can also provide customers with the technical assurance that the application can’t view or modify their data, increasing trust and reducing the risk for customers using the third-party ISV application.
Confidential federated learning
Building and improving AI models for use cases like fraud detection, medical imaging, and drug development requires diverse, carefully labeled datasets for training. This demands collaboration between multiple data owners without compromising the confidentiality and integrity of the individual data sources.
Confidential computing on NVIDIA H100 GPUs unlocks secure multi-party computing use cases like confidential federated learning. Federated learning enables multiple organizations to work together to train or evaluate AI models without having to share each group’s proprietary datasets.
Confidential federated learning with NVIDIA H100 provides an added layer of security that ensures that both data and the local AI models are protected from unauthorized access at each participating site.
When deployed at the federated servers, it also protects the global AI model during aggregation and provides an additional layer of technical assurance that the aggregated model is protected from unauthorized access or modification.
This helps drive the advancement of medical research, expedite drug development, mitigate insurance fraud, and trace money laundering globally while maintaining security, privacy, and regulatory compliance for all parties involved.
NVIDIA platforms for accelerated confidential computing on-premises
Getting started with confidential computing on NVIDIA H100 GPUs requires a CPU that supports a virtual machine (VM)–based TEE technology, such as AMD SEV-SNP and Intel TDX. Extending the VM-based TEE from the supported CPU to the H100 GPU enables all the VM memory to be encrypted and the application running does not require any code changes.
Top OEM partners are now shipping accelerated platforms for confidential computing, powered by NVIDIA H100 Tensor Core GPUs. These confidential computing–compatible systems combine the NVIDIA H100 PCIe Tensor Core GPUs with AMD Milan or AMD Genoa CPUs that support the AMD SEV-SNP technology.
The following partners are delivering the first wave of NVIDIA platforms for enterprises to secure their data, AI models, and applications in use in data centers on-premises:
- ASRock Rack
- Dell Technologies
- Hewlett Packard Enterprise
NVIDIA H100 GPU comes with the VBIOS (firmware) that supports all confidential computing features in the first production release. The NVIDIA confidential computing software stack to be released this summer will support single GPU first and then multi-GPU and Multi-Instance GPU in subsequent releases.
