<DIV>Dear Prof. Marks,</DIV>
<DIV> </DIV>
<DIV>Thanks very much for your suggestions. Now, I know how to set up the parallel calculation and edit .machines. </DIV>
<DIV> </DIV>
<DIV>In addition, I have another question about the performance of my machine with Dual Quad Core Processors (i. e. 8 CPUs). By checking the process, I found eight CPUs of my machine were all used by more than 90%, even when I performed the calculation without k-point parallelization. I have compared these two cases with and without k-point parallelization, and found that they almost took the same time. So, I think it is not necessary to perform k-point parallel calculation in my case, and that this workstation will automatically allocate the mission on average to all eight CPUs . Is my understanding right? Thanks,</DIV>
<DIV> </DIV>
<DIV>Best regards,</DIV>
