[Starpu-devel] support for cudaMemcpyPeer

[Hatem Ltaief <hatem.ltaief@kaust.edu.sa>]

Dear StarPU dev,

StarPU from git branch 1.2 does not detect cudaMemcpyPeer in cuda 9.0.

This cuda function is defined in:

/usr/local/cuda/lib64/libcudart_static.a

000000000003c7f0 T cudaDeviceCanAccessPeer

000000000003c470 T cudaDeviceDisablePeerAccess

000000000003c620 T cudaDeviceEnablePeerAccess

0000000000037820 T cudaMemcpy3DPeer

00000000000482b0 T cudaMemcpy3DPeerAsync

000000000004c010 T cudaMemcpy3DPeerAsync_ptsz

000000000003fac0 T cudaMemcpy3DPeer_ptds

000000000003f2b0 T cudaMemcpyPeer

000000000004bb70 T cudaMemcpyPeerAsync

while StarPU tries to look for it in:

configure:28949: checking for cudaMemcpyPeer

configure:28949: gcc -o conftest -g -O2  -D_GNU_SOURCE  -I/usr/local/cuda/include  -L/usr/local/cuda/lib64 -lcudart -lcublas -lcuda conftest.c -lrt -lm -lpthread  >&5

/tmp/ccNdG8Tq.o: In function `main':

/home/hltaief/codes/starpu/conftest.c:114: undefined reference to `cudaMemcpyPeer'

This is cuda 9.0. Perhaps in earlier versions of cuda, it used to be located there. I can remedy it by adding proper LDFLAGS and LIBS, but wanted to report it.

Thanks!

Hatem
