The post GFN Thursday Gets Groovy As ‘Evil Dead: The Game’ Marks 1,300 Games on GeForce NOW appeared first on NVIDIA Blog.
I’m currently an intern trying to wrap Face-api.js as a component, my problem is – and I think I know too little about to fully understand – the models.
I was wondering if there are other ways to save and load (already feeded) models, other than using script tags. I need to be looking into it to get a better performance rate, but I honestly don’t know if this is even a possibility.

I am migrating from a laptop with a RTX 3080 mobile to a desktop with a RTX3080 Ti. I am using the Tensorflow Docker image from the NGC Catalog (tensorflow:22.03-tf2-py3) in both instances and the same code/dataset. The laptop was running Pop OS 20.04 LTS and the desktop Ubuntu 20.04 LTS, basically the same setup.
The laptop took about 2 seconds per epoch (can’t re test again because I have to turn in the device, but epoch time is stored in the Jupiter notebook) while the desktop (with better a GPU) takes between 4 to 5 seconds. I already re-installed drivers and the whole docker engine with no luck. Currently while checking nvidia-smi gpu usage is only about 30%.
Does anyone has encountered a problem like this? Thanks.

A30 enables researchers, engineers, and data scientists to deliver real-world results and deploy solutions into production at scale.
NVIDIA A30 GPU is built on the latest NVIDIA Ampere Architecture to accelerate diverse workloads like AI inference at scale, enterprise training, and HPC applications for mainstream servers in data centers. The A30 PCIe card combines the third-generation Tensor Cores with large HBM2 memory (24 GB) and fast GPU memory bandwidth (933 GB/s) in a low-power envelope (maximum 165 W).
A30 supports a broad range of math precisions:
It also supports innovations such as Tensor Float 32 (TF32) and Tensor Core FP64, providing a single accelerator to speed up every workload.
Figure 1 shows TF32, which has the range of FP32 and precision of FP16. TF32 is the default option in PyTorch, TensorFlow, and MXNet, so no code change is needed to achieve speedup over the last-generation NVIDIA Volta Architecture.
Another important feature of A30 is Multi-Instance GPU (MIG) capability. MIG can maximize the GPU utilization across big to small workloads and ensure quality of service (QoS). A single A30 can be partitioned to up to four MIG instances to run four applications simultaneously, each fully isolated with its own streaming multiprocessors (SMs), memory, L2 cache, DRAM bandwidth, and decoder. For more information, see Supported MIG Profiles.
For interconnection, A30 supports both PCIe Gen4 (64 GB/s) and the high-speed third-generation NVLink (maximum 200 GB/s). Each A30 can support one NVLink bridge connection with a single adjacent A30 card. Wherever an adjacent pair of A30 cards exists in the server, the pair should be connected by the NVLink bridge that spans two PCIe slots for best bridging performance and balanced bridge topology.

| Design | Small Footprint Data Center & Edge Inference | AI Inference & Mainstream Compute |
| Form Factor | x16 PCIe Gen3 1 slot LP |
x16 PCIe Gen4 2 Slot FHFL 1 NVLink bridge |
| Memory | 16GB GDDR6 | 24GB HBM2 |
| Memory Bandwidth | 320 GB/s | 933 GB/s |
| Multi-Instance GPU | Up to 4 | |
| Media Acceleration | 1 Video Encoder 2 Video Decoder | 1 JPEG Decoder 4 Video Decoder |
| Fast FP64 | No | Yes |
| Ray Tracing | Yes | No |
| Power | 70W | 165W |
In addition to the hardware benefits summarized in Table 1, A30 can achieve higher performance per dollar compared to the T4 GPU. A30 also supports end-to-end software stack solutions:
To analyze the performance improvement of A30 over T4, and CPUs, we benchmarked six models from MLPerf Inference v1.1 with the datasets:
The MLPerf benchmark suite covers a broad range of inference use cases, from image classification and object detection to recommenders, and natural language processing (NLP).
Figure 2 shows the results of the performance comparison of A30 with T4 and CPU on AI inference workloads.A30 is around 300x faster than a CPU for BERT inference.
Compared to T4, A30 delivers around 3-4x performance speedup for inference using the six models. The performance speedup is due to A30 larger memory size. This enables larger batch size for the models and faster GPU memory bandwidth (almost 3x T4), which can send the data to compute cores in a much shorter time.
In addition to AI inference, A30 can rapidly pre-train AI models such as BERT Large with TF32, as well as accelerate HPC applications using FP64 Tensor Cores. A30 Tensor Cores with TF32 provide up to 10x higher performance over the T4 without requiring any changes in your code. They also provide an additional 2x boost with automatic mixed precision, delivering a combined 20x throughput increase.
While building a video analytics or video processing pipeline, there are several operations that must be considered:
Measured performance with DeepStream 5.1. It represents e2e performance with video capture and decode, preprocessing, batching, inference, and post-processing. Output rendering was turned off for optimal perf running ResNet10, ResNet18, and ResNet50 networks for inference on H.264 1080p30 video-streams.
A30 is designed to accelerate intelligent video analysis (IVA) by providing four video decoders, one JPEG decoder, and one optical flow decoder.
To make use of these decoders along with the compute resources for analyzing videos, use the NVIDIA DeepStream SDK, which delivers a complete streaming analytics toolkit for AI-based, multisensor processing, video, audio, and image understanding. For more information, see TAO Toolkit Integration with DeepStream or Building a Real-time Redaction App Using NVIDIA DeepStream, Part 1: Training.
Representing the most powerful end-to-end AI and HPC platform for data centers, A30 enables researchers, engineers, and data scientists to deliver real-world results and deploy solutions into production at scale. For more information, see the NVIDIA A30 Tensor Core GPU datasheet and NVIDIA A30 GPU Accelerator product brief.

Adepth map is an image channel in computer graphics and computer vision that provides information on the distance of the surface of objects as seen from a viewpoint for each pixel in that image. Because of its wide range of applications in augmented reality, portrait mode, and 3D reconstruction, ongoing research in the field of depth-sensing capabilities is being done to pave the way for the future (particularly with the release of the ARCore Depth API). Furthermore, the web community is increasing interest in merging the depth capabilities with JavaScript to enhance the existing web applications by integrating them with real-time AR effects. Despite these recent improvements, the number of photos connected with depth maps continues to be a source of worry. To drive the next generation of web applications, Tensorflow released its first depth estimation API, called Depth API, and ARPortraitDepth, a model for estimating a depth map for portraiture. They also published 3D photo, a computational photography application that uses the anticipated depth and creates a 3D parallax effect on the given portrait image, further persuading people of the enormous possibilities of depth information. Tensorflow has also launched a live demo for people to try and convert their photographs into 3D versions.

The first open-source release of GPU kernel modules for the Linux community help improve NVIDIA GPU driver quality and security.
NVIDIA is now publishing Linux GPU kernel modules as open source with dual GPL/MIT license, starting with the R515 driver release. You can find the source code for these kernel modules in the NVIDIA Open GPU Kernel Modules repo on GitHub.
This release is a significant step toward improving the experience of using NVIDIA GPUs in Linux, for tighter integration with the OS and for developers to debug, integrate, and contribute back. For Linux distribution providers, the open-source modules increase ease of use. They also improve the out-of-the-box user experience to sign and distribute the NVIDIA GPU driver. Canonical and SUSE are able to immediately package the open kernel modules with Ubuntu and SUSE Linux Enterprise Distributions.
Developers can trace into code paths and see how kernel event scheduling is interacting with their workload for faster root cause debugging. In addition, enterprise software developers can now integrate the driver seamlessly into the customized Linux kernel configured for their project.
This will further help improve NVIDIA GPU driver quality and security with input and reviews from the Linux end-user community.
With each new driver release, NVIDIA publishes a snapshot of the source code on GitHub. Community submitted patches are reviewed and if approved, integrated into a future driver release.
Refer to the NVIDIA contribution guidelines and overview of the driver release cadence and life-cycle documentation for more information.
The first release of the open GPU kernel modules is R515. Along with the source code, fully-built and packaged versions of the drivers are provided.
For data center GPUs in the NVIDIA Turing and NVIDIA Ampere architecture families, this code is production ready. This was made possible by the phased rollout of the GSP driver architecture over the past year, designed to make the transition easy for NVIDIA customers. We focused on testing across a wide variety of workloads to ensure feature and performance parity with the proprietary kernel-mode driver.
In the future, functionality such as HMM will be a foundational component for confidential computing on the NVIDIA Hopper architecture.
In this open-source release, support for GeForce and Workstation GPUs is alpha quality. GeForce and Workstation users can use this driver on Turing and NVIDIA Ampere architecture GPUs to run Linux desktops and use features such as multiple displays, G-SYNC, and NVIDIA RTX ray tracing in Vulkan and NVIDIA OptiX. Users can opt in using the kernel module parameter NVreg_EnableUnsupportedGpus as highlighted in the documentation. More robust and fully featured GeForce and Workstation support will follow in subsequent releases and the NVIDIA Open Kernel Modules will eventually supplant the closed-source driver.
Customers with Turing and Ampere GPUs can choose which modules to install. Pre-Turing customers will continue to run the closed source modules.
The open-source kernel-mode driver works with the same firmware and the same user-mode stacks such as CUDA, OpenGL, and Vulkan. However, all components of the driver stack must match versions within a release. For instance, you cannot take a release of the source code, build, and run it with the user-mode stack from a previous or future release.
Refer to the driver README document for instructions on installing the right versions and additional troubleshooting steps.
The R515 release contains precompiled versions of both the closed-source driver and the open-source kernel modules. These versions are mutually exclusive, and the user can make the choice at install time. The default option ensures that silent installs will pick the optimal path for NVIDIA Volta and older GPUs versus Turing+ GPUs.
Users can build kernel modules from the source code and install them with the relevant user-mode drivers.
NVIDIA has been working with Canonical, Red Hat, and SUSE for better packaging, deployment, and support models for our mutual customers.
“The new NVIDIA open-source GPU kernel modules will simplify installs and increase security for Ubuntu users, whether they’re AI/ML developers, gamers, or cloud users,” commented Cindy Goldberg, VP of Silicon alliances at Canonical. “As the makers of Ubuntu, the most popular Linux-based operating system for developers, we can now provide even better support to developers working at the cutting edge of AI and ML by enabling even closer integration with NVIDIA GPUs on Ubuntu.”
In the coming months, the NVIDIA Open GPU kernel modules will make their way into the recently launched Canonical Ubuntu 22.04 LTS.
“We at SUSE are excited that NVIDIA is releasing their GPU kernel-mode driver as open source. This is a true milestone for the open-source community and accelerated computing. SUSE is proud to be the first major Linux distribution to deliver this breakthrough with SUSE Linux Enterprise 15 SP4 in June. Together, NVIDIA and SUSE power your GPU-accelerated computing needs across cloud, data center, and edge with a secure software supply chain and excellence in support.” — Markus Noga, General Manager, Business Critical Linux at SUSE
“Enterprise open source can spur innovation and improve customers’ experience, something that Red Hat has always championed. We applaud NVIDIA’s decision to open source its GPU kernel driver. Red Hat has collaborated with NVIDIA for many years, and we are excited to see them take this next step. We look forward to bringing these capabilities to our customers and to improve interoperability with NVIDIA hardware.” — Mike McGrath, Vice President, Linux Engineering at Red Hat
NVIDIA GPU drivers have been designed over the years to share code across operating systems, GPUs and Jetson SOCs so that we can provide a consistent experience across all our supported platforms. The current codebase does not conform to the Linux kernel design conventions and is not a candidate for Linux upstream.
There are plans to work on an upstream approach with the Linux kernel community and partners such as Canonical, Red Hat, and SUSE.
In the meantime, published source code serves as a reference to help improve the Nouveau driver. Nouveau can leverage the same firmware used by the NVIDIA driver, exposing many GPU functionalities, such as clock management and thermal management, bringing new features to the in-tree Nouveau driver.
Stay tuned for more developments in future driver releases and collaboration on GitHub.
You can download the R515 development driver as part of CUDA Toolkit 11.7, or from the driver downloads page under “Beta” drivers. The R515 data center driver will follow in subsequent releases per our usual cadence.
Yes, the NVIDIA open kernel modules are licensed under a dual GPL/MIT license; and the terms of licenses govern the distribution and repackaging grants.
These changes are for the kernel modules; while the user-mode components are untouched. So the user-mode will remain closed source and published with pre-built binaries in the driver and the CUDA toolkit.
Open kernel modules support all Ampere and Turing GPUs. Datacenter GPUs are supported for production, and support for GeForce and Workstation GPUs is alpha quality. Please refer to the Datacenter, NVIDIA RTX, and GeForce product tables for more details (Turing and above have compute capability of 7.5 or greater).
Problems can be reported through the GitHub repository issue tracker or through our existing end-user support forum. Please report security issues through the channels listed on the GitHub repository security policy.
We encourage community submissions through pull requests on the GitHub page. The submitted patches will be reviewed and if approved, integrated with possible modifications into a future driver release. Please refer to the NVIDIA driver lifecycle document.
The published source code is a snapshot generated from a shared codebase, so contributions may not be reflected as separate Git commits in the GitHub repo. We are working on a process for acknowledging community contributions. We also advise against making significant reformatting of the code for the same reasons.
The process for submitting pull requests is described on our GitHub page and such contributions are covered under the contributor license agreement (CLA).
