One more question, I would be comparing results of this routine with an algorithm based on cyclic reduction, it has been designed to execute with a size specified at compilation time.  Maximum size is about 90,000,000 . Do I have to specify a memory size when requesting for a compute node (example- qsub -I -l nodes=1:gpu:ppn=2 -l mem=32G -d .)  in order to execute the code with this size?

I think yes, You have to estimate the memory requested by getrs for this case and specify this size when will make the queue submission.
