GEMS performance
 
GEMS performance on different hardware platforms has been fully tested. It is evident from the test results that GEMS can reach the good performance on the high performance server cluster, PC cluster, supercomputer, and multiple core processors. GEMS supports Windows and Linux operating systems and online simulation.
