<p style="margin-right: 0px; margin-left: 0px;"><font face="Times New Roman" size="3">However, everything works out with "8 400000", and with "16 400000". This problem is reproducible on my 4-core laptop as well as on the 16-core HP SL203S GEN8 compute node. The
GCC v4.7.3 and Intel v15.0.0 were used to compile MPICH v3.1.3 on my laptop and on HP SL203S, respectively. Moreover, the MPICH v3.1.3 used includes the '920661c3931' commit by Xin Zhao. </font></p>
