Hi,
I'm trying to run code on GPU and I get the following error:
An unexpected error occurred trying to launch a kernel. The CUDA error was:
invalid configuration argument
When I insert a breakpoint at the line that gives this error and run the code manually I get the same error but if I immediately try running it like again the code runs without the error. This proves that my code is not buggy and it is something else that's causing it to crash.
I have seen the same CUDA error using the NaN and subref functions. If it helps at all, here are the exact lines both of which give the same error on first try, but not on second try:
K>> W0(:,ones(1,size(dWU0,3)),:)
Error using gpuArray/subsref
An unexpected error occurred trying to launch a kernel. The CUDA error was:

K>> y = nan(s,'like',x)
Error using gpuArray/nan
An unexpected error occurred trying to launch a kernel. The CUDA error was:
invalid configuration argument
K>> y = nan(s,'like',x)
y =
NaN
This is very perplexing to me. Any thoughts?
