(this is sortof a test to see if I can partake in this discussion)<br><br>Chuck -- Since "smpd" is the deamon/service running between the 2 systems, Perhaps adding that program to the windows firewall as an exception would be enough. I'll send details later once my PC is back up, but I recall you open Windows Firewall, and in there is either a tab or menu for exceptions, and in that area, you browse for the executable to add as the exception.<br>

<div>My two PC's are both 32 bit. I found that the firewall was ON on both PC's. I turned the firewall OFF on both PC's and the run worked just fine. I did not need to use IP numbers.</div>
<div> </div>
<div>Thanks much for getting me to this point.</div>
<div> </div>
<div>Is there a setting of the firewalls I can make that is not as drastic as turning them off completely? Is there a program name or port I can list as an "exception" in the firewall control window?</div>

<div>Sent: Wednesday, April 21, 2010 9:26:51 PM GMT -06:00 US/Canada Central<br>Subject: [mpich-discuss] Getting started in Win XP<br><br><br><br>I downloaded MPICH2 for Windows in Nov, 2009. I installed in on two PC's that I call Issac and Gauss that have access to my home wireless network. The installation file is mpich2-1.2-win-ia32.msi. Issac uses XP-Pro and Gauss uses XP-Home.<br>
<br>I purchased the Intel Fortran compiler, Vers 11.1, in July, 2009, for use on Issac, and I regularly use it there. I compiled the test case, fpi.f, on Issac. I (eventually) got a successful execution on a single PC by using the statement:<br>
<br>mpiexec -hosts 1 Issac 1 fpi.exe<br><br>I issued this command in a directory that contained mpiexec.exe and fpi.exe. I am the only user of this PC, and I do not use a password -- maybe I should say I have a blank password. Anyway the above command line didn't work initially because it asked for a password, and I didn't have one. I then set up a second User Name and gave it a password. Working under that User Name I again issued the above command line and I gave it the password when it asked for it, and it worked!! I was happy.<br>
<br>Moving on to try running this on my two PC's, I tried the command line:<br><br>mpiexec -hosts 2 Issac 1 Gauss 1 fpi.exe<br><br>I had Gauss running with a User Name that has a password (which may or may not have any bearing on the situation.)<br>
<br>This failed with the message:<br><br>launch failed: CreateProcess(fpi.exe) on 'Gauss' failed, error 2 - The system cannot find the file specified.<br><br>Then I tried giving fpi.exe a full path. I used:<br><br>
mpiexec -hosts 2 Issac 1 Gauss 1 \\Issac\mpi\fpi.exe<br><br>That got further, but still not a complete execution. This responded with:<br>Process 0 of 2 is alive<br>Enter the number of intervals: (0 quits)<br>Process 1 of 2 is alive<br>
<br>I entered 50, but there was no response. I entered 0 and still no response, so I killed the run.<br><br>I added four Fortran write statements into the test case, fpi.f. Before and after the Call MPI_BCAST and before and after the Call MPI_REDUCE. Each write included the value of myid in the output. I recompiled that. I then tried the last command line above again. It responded with:<br>
<br>Process 0 of 2 is alive<br>Enter the number of intervals: (0 quits)<br>Process 1 of 2 is alive<br>Proc 1 before call MPI_BCAST <= My debug write.<br>50 <= My entry from the keyboard.<br>Proc 0 before call MPI_BCAST <= My debug write.<br>
<br>and then just hung at that stage.<br><br>I conclude that fpi.exe is executing on both PC's, and on both PC's it has successfully gotten through calls to MPI_INIT, MPI_COMM_RANK and MPI_COMM_SIZE. The "print ... alive" statement functioned correctly on both PC's. Execution continued correctly up to the Call to MPI_BCAST. There it died. Why?<br>
<br>I will greatly apprciate suggestions as to how to get this test case to run correctly. I am well acquainted with Fortran programming, but not well acquainted with lower level operating system or networking components.<br>
<br>Hoping for help,<br><br>Chuck<br>=====<br><br><br><br><br><br></div></div>
