I`ve installed vasp.5.1.2 using intel 11.1.059 compiler,
and I`ve tested sdi_vasp_test.
Now, I`ve got strange results.
The result for 1core in 1node
Total CPU time used (sec): 66492.586
User time (sec): 64741.515
System time (sec): 1751.074
Elapsed time (sec): 25813.238
The result for 2core in 1node
Total CPU time used (sec): 72281.367
User time (sec): 70431.948
System time (sec): 1849.418
Elapsed time (sec): 36689.873
The result for 4core in 1node
Total CPU time used (sec): 70876.625
User time (sec): 69397.354
System time (sec): 1479.271
Elapsed time (sec): 41525.315
I think, more core can be get more perfomance, but results tell me not.
Can you explain the reason??
