Latest Nsight Developer Tools Releases: Nsight Systems 2021.2, Nsight Compute 2021.1, Nsight Visual Studio Code Edition

Today we announced the latest versions of Nsight Systems 2021.2 and Nsight Compute 2021.1 – now available with new features for GPU profiling and performance optimization.

We also announced the Nsight Visual Studio Code Edition, NVIDIA’s new addition to the series of world class developer tools for CUDA programming and debugging. 

Nsight Systems 2021.2

Nsight Systems 2021.2, introduces support for GPU metrics sampling and tracing of CUDA Unified Memory page faults on the CPU and GPU. There’s also support for Reflex SDK, CUDA 11.3, and additional enhancements in network trace, including: NCCL, NVSHMEM, OpenSHMEM, and MPI fortran.

The GPU metrics sampling feature allows you to view and analyze low level utilization details on a timeline. These provide a system wide overview of efficiency for your GPU workloads. They include metrics on IO activity including throughput for PCIe, NVLink, and DRAM. They also show SM utilization, TensorCore activity, instructions issued, warp occupancy and unallocated warps.

This expands Nsight Systems ability to profile system-wide activity and help track GPU workloads and their CPU origins. By providing a deeper understanding of the GPU utilization over multiple processes and contexts; covering the interop of Graphics and Compute workloads including CUDA, OptiX, DirectX and Vulkan ray tracing + rasterization APIs.
