mpiexec wrapper (wmpiexec). The mpiexec wrapper invokes (under the
hood) mpiexec to launch your MPI job (Click on "Show command" button to see
the full command).</SPAN></FONT></DIV>

<DIV></DIV>Thank you for your help. <BR> <BR>I would like to know whether I
can run the processes in this way: <BR> <BR>I debug a program and get
a .exe .For example, hello.exe. <BR> <BR>Then I use the MPICHEXEC wrapper
to load the hello.exe and choose number of process equal to 2. Then
press execute to run the program?<BR> <BR>Can I get an answer in this

<DIV></DIV>Dear Sir ,<BR> <BR>This is the first time I use MPICH2. I
install the software and the SMPD.exe is in the process list. <BR>But when I run
the example code I meet errors as follows: <BR> <BR>[0] Error creating
mpiexec process...2<BR>[0] launchMpiexecProcess failed<BR>Fatal error in
MPI_Init: Other MPI error, error stack:<BR>MPIR_Init_thread(294): Initialization
failed<BR>MPID_Init(82)........: channel initialization
failed<BR>MPID_Init(383).......: PMI_Get_id returned 1<BR> <BR>I tried
placed the mpiexec together with the example cpde but it does no help.<BR>Then I
use wmpiexec to run the programme. But when I press the execute button . The
empty command window will flash for a second and then disappeared, and now error
message.<BR> <BR>I would like to know what may cause this
problem.<BR> <BR>I read some suggestion that "<FONT size=2> The error
indicates that the path for the job launcher (mpiexec) was not found.<BR>
Please set the path for MPICH2 binaries on your system ("Control Panel" -->
System --> Advanced --> "Environment Variables" => Add MPICH2 bin
to the PATH). Now open a new command prompt, try running mpiexec from command
prompt (to make sure that you have the PATH set correctly) and then run your
code."</FONT><BR><FONT size=2>And tried it but it does no help.</FONT><BR><FONT

you.</FONT><BR><BR><BR><BR>
