Updates in 2021.1.0

General
  • Added support for the CUDA toolkit 11.3, including
    • Nsight Compute Resource Tracking for new CUDA 11.3's features:
      • CUDA Graph's User Objects
      • Stream Ordered CUDA Memory Allocator's memory allocations from Memory Pools
      • Stream Captured CUDA Graph Nodes
  • Added support for the OptiX 7 API.
  • GpuArch enumeration values used for filtering in section files were renamed from architecture names to compute capabilities.
  • NVTX states can now be accessed via the NvRules API.
  • Added a rule for the Occupancy section.
NVIDIA Nsight Compute
  • Added support for new CUDA asynchronous allocator attributes in the Memory Pools resources view.
  • Added a topology chart and link properties table in the NVLink section.
  • The selected metric column is scrolled into view on the Source page when a new metric is selected.
  • Users can choose the Source heatmap color scale in the Options dialog.
NVIDIA Nsight Compute CLI
  • Added file-based application replay as the new default application replay mode. File-based replay uses a temporary file for keeping replay data, instead of allocating them in memory. This keeps the required memory footprint close to constant, independent of the number of profiled kernels. Users can switch between buffer modes using the --app-replay-buffer option.
  • CLI output now shows NVTX color and message information.
  • --kernel-regex and --kernel-regex-base options are deprecated and replaced by --kernel-name and --kernel-name-base, respectively.
  • All options which support regex need to provide regex: as a prefix before an argument to match per the regex, e.g <option> <regex:expression>
Resolved Issues
  • Fixed that baselines were not updated properly on the Comments page.
  • Fixed that NVTX ranges named using their payloads can be used in NVTX filtering expressions.
  • Fixed crashes in MacOSX hosts when terminating the target application.
  • The NVLINK(nvl*) metrics are now added back.
