Thanks for your interest!
GPU: GeForce GTX 275
According to the table on <https://en.wikipedia.org/wiki/CUDA>, GeForce
GTX 275 supports Compute Capability 1.3, but GCC (in particular, the
nvptx backend) only supports 3.0 and higher.
libgomp: cuMemHostGetDevicePointer error: invalid device
Not an ideal error message, I agree.
I would like to mention that CUDA is working well on my machine.
Is it a misconfiguration/miscompilation of myself while compiling gcc or
a bug in libgomp?
Missing support in GCC's nvptx backend, primarily. And, that's unlikely
to be added, unless someone steps up to contribute/maintain such support.
