Hi Matt,
I got a run-time error when one of Rodinia suite was run on nvidia GPU: FATAL ERROR: variable in data clause is partially present on the device: name=conn
I noticed that this error happened in line 226 of “backprop.c” file (“conn” variable): conn is a 2-D array and in present clause, it appears as conn[0:n1n2]. The compiling info said: Generating present(l1[:n1],l2[:n2],conn[:1][:n1n2]). It should be conn[:n1][:n2], not conn[:1][:n1*n2]. So I change it in original file. But there is still another error when I run it (./backprop 16): call to cuStreamSynchronize returned error 700: Illegal address during kernel execution.
A quick way to get them is this download link: https://github.com/pathscale/rodinia. After unzip the file, please go to: rodinia-master/openacc/backprop
Totally there are 6 files(backprop.c, backprop.h, backprop_kernel.c, facetrain.c, imagenet.c, README, run and Makefile).
If you have problems to download it, I will post them or let PGI Customer Service (trs@pgroup.com) to forward it to you.
Here is PGI info:
