I am trying to profile a kernel. Apparently it works well, and gives the expected output. I am unable to find any problem using both cuda-gdb and cuda-memcheck. I can profile it using this commands:
nvprof ./test nvprof -o test2.nvvp ./test
but when I try this:
nvprof --analysis-metrics -o test.nvvp ./test
It stops with the error:
==23785== Some kernel(s) will be replayed on device 0 in order to collect all events/metrics. ==23785== Warning: PC Sampling is not supported on the underlying platform. Replaying kernel "void kernelDecompress<float>(float*, unsigned int*, unsigned char const *, int const *, long const *, int, int, int, int)" (3 of 52)... tex0_cache_sector_misses tex2_cache_sector_misses l2_subp2_read_l1_sector_queries 4 internal events ==23785== Error: Internal profiling error 4075:999.
If I try with the options:
nvprof --metrics all -o test2.nvvp ./test
It ends with the same error.
I have been unable to find this error in the forums, is there a known workaround to this?
I am using a Tesla k80 card, and cuda version 10.1.105.
Thanks for your help.
