<P><FONT size=2> Hi,<BR> If you are running your executable from a |
|---|
| 120 |
shared network drive you need to map (see "--map" option of mpiexec in the |
|---|
| 121 |
window's developer's guide) the network drive with mpiexec when launching your |
|---|
| 122 |
job.<BR> Also make sure that you have turned the windows firewall (or any |
|---|
| 123 |
other firewalls) off on the machines involved in the job.<BR> Try |
|---|
| 124 |
specifying the ip addresses of the machines instead of the hostnames.<BR> |
|---|
| 125 |
Let us know the results.<BR><BR>(PS: Instead of the "-hosts" option you could |
|---|
| 126 |
try using the "-machinefile" option available with mpiexec. See the window's |
|---|
| 127 |
developer's guide for details.)<BR><BR>Regards,<BR>Jayesh<BR>-----Original |
