  • Fixed an issue that reported the wrong executable name in the Session page when attaching
  • Fixed issues that chart labels were shown elided on the Details page
  • Fixed an issue that caused the cache hitrates to be shown incorrectly when baselines were added
  • Fixed an illegal memory access when collecting sass__*_histogram metrics for applications using PyTorch on Pascal GPUs
  • Fixed an issue when attempting to collect all smsp__* metrics on Volta and newer GPUs
  • Fixed an issue when profiling multi-context applications
  • Fixed that profiling start/stop settings from the connection dialog weren't properly passed to the interactive profile activity
  • Fixed that certain smsp__warp_cycles_per_issue_stall* metrics returned negative values on Pascal GPUs
