<DIV>Hi,<BR><BR>
<DIV class="body">I have an computer with Core i5 CPU and 4 GB of RAM, running the MS win7 64-bit operating system. I am trying to run 'cpi.exe' in the folder 'examples' after I install 'mpich2-1.3.2p1-win-x86-64.exe'. If I just type 'cpi' in the cmd, the program run normally. And at 'Windows Task Manager',I see only one of four CPUs are occupied fully. Then I type 'mpiexec -n 2 cpi', 'mpiexec.exe -n 1 -noprompt cpi.exe' and so on. it comes out the same error message:</DIV>
<DIV class="body"><BR><FONT color="#f00000">Error while connecting to host. No connection could be made because the target machine actively refused it. (10061)<BR>Connect on sock (host=Owner-PC, port=8676) failed, exhaused all end points<BR>Unable to connect to 'Owner-PC:8676', sock error: Error = -1<BR><BR></FONT>I am the administrator on this computer, and I am not trying to connect to another machine, to my knowledge. Besides, the firewall is disabled.</DIV>
<DIV class="body">I think maybe I mixed MSMPI and MPICH2, but I don't find the folder 'Microsoft Compute Cluster Packany', which I think the MSMPI should be, at "C:\Program Files" or "C:\Program Files(*86)". </DIV>
<DIV class="body">So, what am I doing wrong?<BR><BR>Any help to solve this error is highly appreciated.<BR><BR><BR>Best regards,<BR><BR>Kai<BR><SPAN title="neteasefooter"><SPAN id="netease_mail_footer"></SPAN></SPAN></DIV></DIV><BR><BR><SPAN title="neteasefooter"><SPAN id="netease_mail_footer"></SPAN></SPAN><br><br><span title="neteasefooter"><span id="netease_mail_footer"></span></span>
