<P><FONT SIZE=2> Hi,<BR>
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.<BR>
<BR>

Subject: [mpich-discuss] Error with MPI<BR>
<BR>
Hi,<BR>
<BR>
my MPICH and MPICH2 used to be running fine. A few days ago, my hdd crashed and MPICH2 is affected. My windows xp is not affected. I tried to repair, uninstall and reinstall the installation. Now, when I compile and run a code (e.g. PETSc code), I get the following error:<BR>
<BR>
(MPICH2)<BR>
<BR>
$ ./ex1f<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>
When running the fpi example, I also get errors with more than 1 process. It shows for 4 processes: (MPICH and MPICH2)<BR>
<BR>
Process 0 of 1 is alive<BR>
Enter the number of intervals: (0 quits)<BR>
Process 0 of 1 is alive<BR>
Enter the number of intervals: (0 quits)<BR>
Process 0 of 1 is alive<BR>
Enter the number of intervals: (0 quits)<BR>
Process 0 of 1 is alive<BR>
Enter the number of intervals: (0 quits)<BR>
<BR>
I wonder why.<BR>
<BR>
Also, in my mpi cfd code, all my codes are compiled with default real kind = 8. However, in one fortran file, I compiled with real kind = 4.<BR>
This used to be working fine in serial. However when compiled with mpi, I get the following error: (MPICH). If I remove part of the code in that file and compile with real kind = 8, there is no such problem, although my process is still limited to 1.<BR>
<BR>
Error 10035, process 0:<BR>
SendInitDataToRoot: recv ack failed<BR>
Error 8, process 0:<BR>
CreateThread failed in ControlLoopThread.<BR>
A non-blocking socket operation could not be completed immediately.<BR>
Not enough storage is available to process this command.<BR>
<BR>
Do you know why this is so?<BR>
<BR>
Thank you very much.<BR>
<BR>
Regards<BR>
