CUPTI

What's New

CUPTI contains a number of changes and new features as part of the CUDA Toolkit 5.5 release.
  • Applications that use CUDA Dynamic Parallelism can now be profiled using CUPTI. Device-side kernel launches are reported using a new activity kind.
  • Device attributes such as power usage, clocks, thermals, etc. are now reported via a new activity kind.
  • A new activity buffer API uses callbacks to request and return buffers of activity records. The existing cuptiActivityEnqueueBuffer and cuptiActivityDequeueBuffer functions are still supported but are deprecated and will be removed in a future release.
  • The Event API supports kernel replay so that any number of events can be collected during a single run of the application.
  • A new metric API cuptiMetricGetValue2 allows metric values to be calculated for any device, even if that device is not available on the system.
  • CUDA peer-to-peer memory copies are reported explicitly via the activity API. In previous releases these memory copies were only partially reported.
