I am using spmd to run the same program on 4 sets of data. In one of the functions I need to do matrix operations on very huge matrices. Is it possible/advisable to use gpuArray here?

Have you tried? ;-) Yes, you can and it is advised. But if you only have one GPU and it's doing all the computation, you may not see much benefit from the additional parallelisation on the CPU.
