(GRE Success! ) phd in high performance computing

Hi,

I am planning to join M.S in MIS/IS next year.

For e.g:-i)http://mays.tamu.edu/info/prospective/undergraduate/mis/
ii)http://business.uc.edu/programs/graduate/ms-is/academics.html


Is it possible to pursue a phd in High Performance Computing and Parallel Computation after this? Or, an MS in computer science/engineering is preferred/required for it?:



With Regards,
