Updates in 2019.5 — NsightCompute 13.1 documentation

# Updates in 2019.5

General

- Added section sets to reduce the default overhead and make it easier to configure metric sets for profiling

- Reduced the size of the installation

- Added support for CUDA Graphs Recapture API

- The NvRules API now supports accessing correlation IDs for instanced metrics

- Added breakdown tables for SOL SM and SOL Memory in the Speed Of Light section for Volta+ GPUs

NVIDIA Nsight Compute

- Added a snap-select feature to the Source page heatmap help navigate large files

- Added support for loading remote CUDA-C source files via SSH on demand for Linux x86_64 targets

- Charts on the Details page provide better help in tool tips when hovering metric names

- Improved the performance of the Source page when scrolling or collapsing

- The charts for Warp States and Compute pipelines are now sorted by value

NVIDIA Nsight Compute CLI

- Added support for GPU cache control, see `--cache-control`

- Added support for setting the kernel name base in command line output, see `--kernel-base`

- Added support for listing the available names for `--chips`, see `--list-chips`

- Improved the stability on Windows when using `--target-processes all`

- Reduced the profiling overhead for small metric sets in applications with many kernels

Resolved Issues

- Reduced the overhead caused by demangling kernel names multiple times

- Fixed an issue that kernel names were not demangled in CUDA Graph Nodes resources window

- The connection dialog better disables unsupported combinations or warns of invalid entries

- Fixed metric thread_inst_executed_true to derive from smsp_not_predicated_off_thread_inst_executed on Volta+ GPUs

- Fixed an issue with computing the theoretical occupancy on GV100

- Selecting an entry on the Source page heatmap no longer selects the respective source line, to avoid losing the current selection

- Fixed the current view indicator of the Source page heatmap to be line-accurate

- Fixed an issue when comparing metrics from Pascal and later architectures on the Summary page

- Fixed an issue that metrics representing constant values on Volta+ couldn’t be collected without non-constant metrics
