MPICH2 1.3.3 did not remove the requirement for smpd.exe .<br>
When using the "-localonly' option with mpiexec you do not need to have SMPD installed on the system. MPICH2 1.3.3 removed firewall issues when starting MPI jobs with the "-localonly" option.<br>
So you still need SMPD to be available, but you don't need to install SMPD or worry about firewall issues when running all MPI processes on the local node.<br>

Subject: [mpich-discuss] No requirement for smpd.exe in MPICH2-1.3.3<br>
<br>
I came across a note @ <a href="http://boinc.berkley.edu">boinc.berkley.edu</a> that stated mpich2-1.3.3 should remove the requirement for smpd.exe, as well as no firewall issues on Windows. I've downloaded and tried this method with the mpich-1.3.3r1-win-ia32 install and using the following command line "mpiexec -localonly -n 2 -channel nemesis:none cpi.exe" but it simply returns the following error "Uknown option -d". Will these functionality be included in the MPICH2-1.3.3 release?<br>
<br>
Thanks,<br>
<br>
Bobby<br>
