Hi,<br><br>we use Platform LSF to dispatch Jobs in our Cluster<br>NX-Client 3.2.X - 3.3.X (Windows, Ubuntu, ThinClient, ...)<br>FreeNX 0.7.4-svn613 with latest patches from mailing list<br>nx-3.3.0-16<br>RHEL 4 64bit<br><br>
we use different Matlab Versions on RH 7.2 / RHEL 3 and RHEL 4 (for everyone who doesn't know: RHEL RedHatEnterprise)<br><br>the prompt in Matlab takes between 10 and 30 Seconds depending on what hardware the job got and depending on the matlab version so I guess your startup time is pretty ok for clustered usage.<br>

so I was also talking about the cluster scheduling instead. Anyways,<br> here are some numbers from my Matlab environment. Could you compare it<br> with yours when you get a chance and let me know how bad mine are:<br><br>
NX Client - 3.3.0.6 - Mac OS X<br> FreeNX Server - 0.7.2-1.1 - OpenSUSE 10.3<br><br> Cluster resource manager - Torque - 2.3.6<br> Cluster Scheduler - Moab<br><br> I start NX client and connect to the cluster head node. Either using<br>
SSH -X or using qsub -X (Torque-specific), I then connect to a compute<br> node. Then I start Matlab. It takes about 15 seconds to get the prompt<br> inside of the Matlab GUI's command screen. How bad is this time for<br>
startup?<br><br> Thanks,<br><br>Prakash<br><br>________________________________________________________________<br> Were you helped on this list with your FreeNX problem?<br> Then please write up the solution in the FreeNX Wiki/FAQ:<br>
