<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>I am having some
issues executing a program through mpiexec. I can run locally on a 4-core
processor with no problem using the -host switch. When I define a machinefile I
get the following error:</FONT></SPAN></DIV>
<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>" Too few entries in
machinefile"</FONT></SPAN></DIV>
<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>This error is not
covered in the manual or FAQs and Google has been of little assistance. I have
tried the following to no avail:</FONT></SPAN></DIV>

<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>1. An old entry in
the list-serve archives recommended a series of commands like the
following mpiexec -machinefile mf1.txt -n 1 cpi.exe : -machinefile mf2.txt
-n 2 This yields the same error for too few
entries.</FONT></SPAN></DIV>

<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>2. The wiki
recommends two course of actions :</FONT></SPAN></DIV>
<DIV><SPAN class=639060312-20072010> <FONT face=Arial
size=2>a) using the -f switch instead of the -machinefile This
gets an error that -f needs to be used on its own</FONT></SPAN></DIV>
<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>
b) setting the HYDRA_HOST_FILE variable with no need for any additional switch.
This just runs all processes on the local machine</FONT></SPAN></DIV>

<DIV><SPAN class=639060312-20072010><FONT face=Arial size=2>I am attempting to
run a parallel program written by Los Alamos across three nodes, each with 4
cores per node. Any assistance would be greatly appreciated</FONT></SPAN></DIV>
