Spiral error on convolution with GPUs

[petermcLBL]

Spiral fails on examples/rconv on GPUs with these files, (attached with ".txt" suffix so github will allow them):

rconv.h
rconv2.fftx.cpp
rconv3.fftx.cpp
testrconv.cu

On cori.nersc.gov: module load cgpu cuda cmake python PrgEnv-intel In build directory:

cmake -D_codegen=GPU ..
make install

Also attached generated Spiral script rconv3.fftx.generator.g (with ".txt" suffix so github will allow it). rconv.h.txt rconv2.fftx.cpp.txt rconv3.fftx.cpp.txt rconv3.fftx.generator.g.txt testrconv.cu.txt

What happens when we build:

Scanning dependencies of target NAME.rconv.rconv3.fftx.generator.g
[ 26%] Built target NAME.rconv.rconv3.fftx.generator.g
[ 28%] Generating code for rconv3.fftx.source.cu

There is a question about whether it doesn't work because of unsupported sizes. So I tried setting nx, ny, nz all to 80 in rconv.h, and I get the same error.
