Re: [Starpu-devel] Starpu stats about disk, OOC, and swapping

[Amani Alonazi <amani.alonazi@kaust.edu.sa>]

yes, it does set the STARPU_CUDA_ASYNC flags in the codelet:

#ifdef STARPU_CUDA_ASYNC
#define CODELET_CUDA_FLAGS(flags) .cuda_flags = {(flags)},

I also was wondering if it's actually defined I added a compile-time-buggy text in the phrase below but it compiles. In theory, at least 10 executives computations shall appear concurrent with the desk write.

#ifndef STARPU_CUDA_ASYNC

  error here * 10^6

  cudaStreamSynchronize( stream );
#endif

By memcpy, I guess you mean a cpu-only memcpy?
