how to increase CPU usage when use bicgstab?

I am using bicgstab to solve a large system of linear equations. however, only 2 cores work out of 4 on my desktop; and when I do my calculation on supercomputer, only around 4~5 cores work out of 64 cores. How do I increase my CPU usage?

You can use GPU coder product that comes with R2017b to leverage the power of GPUs while working with bicgstab.

Thanks Mandar. It seems that there is no easy way to solve the problem, like 'parpool' in which we can specify the number of parallel cores.
