I have thought about this a little, but haven't tried it.
Compiling it "as-is" would give you the same result as you would get compiling
the standard way
since there are no directives for compiling the code to run on the GPU.
I haven't seen anyone mention that they had used CUDA on GLPK. It would take
some re-engineering to
develop the host and device partitions. If you profile glpk on a large
problem, I think you'll find it
spends a good deal of time in some matrix decomposition-type functions. These
would be good
candidates for device kernels.
If you try any of this, keep us posted on your progress!
