Debugging with cuda-gdb causes problems #155

Open minihu-crypto opened 1 year ago

minihu-crypto commented 1 year ago

When I use cuda-gdb to debug all_reduce_perf, there will be

warnings:Cannot parse .gnu_debugdata section; LZMA support was disabled at compile time.

Then the program will repeatedly appear

warning: Cuda API error detected: cudaDeviceEnablePeerAccess returned (0x2c0)
warning: Cuda API error detected: cudaGetLastError returned (0x2c0)

This problem does not occur if I execute all_reduce_perf directly
