CUDA test failing

[willwilliams]

Out of the box I'm seeing ptest.lua in asyncsgd fail when I set:

local usecuda = true

I get the following:

$ mpiexec -np 2 luajit ptest.lua

rank 1 is client.
rank 0 is server.
0   use cpu
1   use gpu 1

This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

It looks like the problem is that the storages that are referenced in the asynchronous send/receives are actually CudaStorages which point to GPU memory. Should they in fact be FloatStorages? If I hack each CudaTensor to have a corresponding FloatStorage then it seems to work.

Thanks.

You might not install the mpi correctly, maybe you can try to install the lastest openmpi with the following: ./configure --prefix=$POME/exe/$MPI --with-cuda=$POME/exe/cuda
