Hi,<br><br> I am running a parallel code in a cluster using mpich 2. However, the process shows a CPU utilization of < 10%. The serial code when run shows a 100% cpu usage. Do the mpi codes show a less cpu usage?<br>

Hi,<br>
Can you run a simple program using mpiexec from the command prompt (mpiexec -n 2 hostname)? Is the process manager, smpd, running on your machine (smpd -status)?<br>
<br>
Regards,<br>
Jayesh<br>

<br>
<br>
Using MPICH2 1.1 on Windows 7 RC, I'm getting wmpiconfig error "MPICH2 not installed or unable to query the host". I've registered my local account (MACHINE\User) for smpd access with wmpiregister. I installed MPICH2 with installation option "for this user only" into my home directory (C:\Users\User). I have administrator privileges.<br>
<br>
Any clues?<br>
<br>
During the installation, at UAC prompt I was asked which networks do I authorize smpd to have access to - private or/and public, and I chose private only. Could that be the culprit?<br>
<br>
Thanks<br>

Hi,<br>
<br>
I try to build/run the example cxxpi.cxx on Sol86 using mpicxx. Compile<br>
seems OK. But when I run it, it shows error as:<br>
<br>
chfcsx023:/home/shangliw/libraries/mpich2-1.0.8p1/examples/testcase_1 ><br>

<br>
<br>
The same file can build/run on Sun4v/Linux without any problem. Would<br>
someone help me to understand what's wrong on Sol86?<br>
<br>
Thanks<br>
