I am trying to trace my OpenCL application using Nsight. It used to work fine for a long time but suddenly all I get is this error:
Error : No events written to file.
I’m not sure what broke it (latest Windows update, driver update, Nsight itself…).
It still works if I trace for example Nvidia’s OpenCL scan example. The project explorer shows that these dlls are loaded while running the scan example:
When I run my application both Nvda.Events.*.dlls are missing (I guess that explains why there are no events written to the file).
All these things do not work:
reverting to an older driver
use an older Nsight version
Restore Windows to an older System restore point
Could this maybe happen because I load OpenCL.dll with LoadLibrary and get the function pointers with GetProcAddress instead of linking to some OpenCL.lib? If that’s the case why did it work before?
Driver version: 320.00
Graphics cards: Quadro 6000, K5000, FX 1800M (doesn’t work on any of them)
Visual Studio 2010 with SP1
Win7, 64 bit
I’m a bit lost here. Does anybody have any suggestions?
