What is cuda11?

CUDA 11 provides a foundational development environment for building applications for the NVIDIA Ampere GPU architecture and powerful server platforms built on the NVIDIA A100 for AI, data analytics, and HPC workloads, both for on-premises (DGX A100) and cloud (HGX A100) deployments.

What is GA102?

NVIDIA’s GA102 GPU uses the Ampere architecture and is made using a 8 nm production process at Samsung. With a die size of 628 mm² and a transistor count of 28,300 million it is a very big chip. GA102 supports DirectX 12 Ultimate (Feature Level 12_2). The GPU also contains 84 raytracing acceleration cores.

How many CUDA cores does the A100 have?

6912 CUDA cores
The A100 features 19.5 teraflops of FP32 performance, 6912 CUDA cores, 40GB of graphics memory, and 1.6TB/s of graphics memory bandwidth.

What is SXM2?

SXM2 is NVIDIA’s form factor for GPUs that allows for NVLlink GPU-to-GPU communication which is significantly faster than over the PCIe bus. The installation of SXM2 GPUs is significantly more difficult than that of PCIe GPUs, so we made a quick video of the process.

What is NVSwitch?

NVSwitch is an NVLink switch chip with 18 ports of NVLink per switch. Internally, the processor is an 18 x 18-port, fully connected crossbar. Any port can communicate with any other port at full NVLink speed, 50 GB/s, for a total of 900 GB/s of aggregate switch bandwidth.

What is TensorRT?

NVIDIA ® TensorRT™ is an SDK for high-performance deep learning inference. It includes a deep learning inference optimizer and runtime that delivers low latency and high throughput for deep learning inference applications.

What is a CUDA kernel?

The kernel is a function executed on the GPU. CUDA kernels are subdivided into blocks. A group of threads is called a CUDA block. CUDA blocks are grouped into a grid. A kernel is executed as a grid of blocks of threads (Figure 2).

What is GA104?

NVIDIA’s GA104 GPU uses the Ampere architecture and is made using a 8 nm production process at Samsung. With a die size of 392 mm² and a transistor count of 17,400 million it is a large chip. GA104 supports DirectX 12 Ultimate (Feature Level 12_2). The GPU also contains 48 raytracing acceleration cores.

How much RAM does the 3090 have?

Also included are 328 tensor cores which help improve the speed of machine learning applications. The card also has 82 raytracing acceleration cores. NVIDIA has paired 24 GB GDDR6X memory with the GeForce RTX 3090, which are connected using a 384-bit memory interface.

Is Ampere better than Turing?

Compared to the Turing GPU Architecture, the NVIDIA Ampere Architecture is up to 1.7x faster in traditional raster graphics workloads and up to 2x faster in ray tracing.

What is the die size of the A100?

Its die size is 826 square millimeters, which is larger than both the V100 (815mm2) and the NVIDIA’s flagship gaming card, the RTX 2080 Ti (754mm2). Those might not sound like big differences, but the A100 is NVIDIA’s first GPU to be built on TSMC’s 7nm process — its current models are on 12nm.

What is the difference between the A100 and the V100?

Sparsity features are described in detail in the A100 introduces fine-grained structured Sparsity section later in this post. The larger and faster L1 cache and shared memory unit in A100 provides 1.5x the aggregate capacity per SM compared to V100 (192 KB vs. 128 KB per SM) to deliver additional acceleration for many HPC and AI workloads.

What is the difference between A100 and V100 L2 cache?

The A100 GPU includes 40 MB of L2 cache, which is 6.7x larger than V100 L2 cache.The L2 cache is divided into two partitions to enable higher bandwidth and lower latency memory access. Each L2 partition localizes and caches data for memory accesses from SMs in the GPCs directly connected to the partition.

How big is the Nvidia A100 GPU?

NVIDIA was a little hazy on the finer details of Ampere, but what we do know is that the A100 GPU is huge. Its die size is 826 square millimeters, which is larger than both the V100 (815mm2) and the NVIDIA’s flagship gaming card, the RTX 2080 Ti (754mm2).
