Hi,

By default RSM uses the directory /tmp on the cluster to save (log?) files. Is there a way to change this default folder?

Also, results on the server can be 10s of GB. For fastest file transfer between client and server (UGE cluster) which option is recommended? RSM internal or network share or external mechanism(what mechanism?) Or they are all the same and network connection speed/bandwidth is the only factor impacting file transfer?

thanks,

Moved to the installation and licensing category where it might receive more visibility. Please take a moment to review the Guidelines if you haven't already.

Hi Ali,

 

I assume you are referring to the staging directory.  This is the directory that RSM copies your project to on the cluster.

To change the location of the staging directory please do the following:

On the client machine (I believe windows in your case) open the RSM Client Utlities:

Start -> Ansys XX.X -> RSM Configuration xx.x

Select the Cluster config on the left, and then click on the "File Management" tab on the right.

If using RSM Internal file transfer mechanism, you will see /tmp there in the "Staging directory path on cluster"

Change that to the location you want the files copied to.  Please note that the compute servers on the cluster will also need access to that path.

 

Once you change the path, click "Apply" at the bottom, and then click on the "Queues" tab.

That will save your settings.

 

Regarding transfer speeds.  That is mostly limited by your network infrastructure.  RSM Internal Transfer and Operating System File transfer are about the same, and external will most likely be slower.  If going from Windows to Linux, I would stick with RSM Internal File transfer as that will likely be slightly faster than using a Samba share for linux, or something similar.

Thank you,

Jake

thanks for the response. No the staging directory is different from the /tmp.  The staging directory is apparently used for keeping result files while the simulation is running.  The /tmp directory seems to save some log files or some non-result files. Still the folder can get large, in the order of several GBs. This /tmp folder is also used by other users of the cluster (not necessarily ANSYS runs).

Hi alitabei,

I see, so you would like to change the log file directory.

On the cluster side, edit the following file:

/ansys_inc/v192/RSM/Config/Ans.Rsm.AppSettings.config

Do a search for:
ServiceLogDirectory

For example you will find:

 

Between the quotes for the 'value' property,  you can put in a new path.

 

There will be four locations to change the "ServiceLogDirectory".

 

Once you change those, please restart the RSM Launcher Service on the cluster.

The changes will not take effect until that is done.

 

Then the RSM logs should be written out to the new location you specified.

 

Thank you,

Jake
