Prerequisites for Large Scale DSO

Ansys Electronics Desktop must be installed on the cluster that runs either a supported scheduler or Ansys RSM.
The cluster is compatible with large Scale DSO Requirements
For releases before 19.0, the input projects for Large Scale DSO jobs distributed to multiple hosts are normally required to be on a shared drive. Beginning with the 19.0 release, this requirement is eliminated for most cases. For the RSM scenario, the shared drive requirement is eliminated, but the project must be accessible on the local host, which must be the first host for the job. For the scheduler scenario, because the job can get started on any of the compute nodes based upon what is allocated to the job by scheduler, users may still need to have the project on a shared drive. However some customers have their own job scripts for job spooling, which copy the project from the source location to a local folder on the first execution host of the job. Such customers will no longer need shared drive for their projects.
Every node of the cluster supports the disk space (in temp directory) and memory requirements of multiple engines that run in parallel.
All the machines allocated to Large Scale DSO job must all come from the same platform, Windows or LINUX.

On the Windows platform, RSM (ansoftrsm.exe) is started as an ’admin’ account, rather than as a ’system’ account.

Note: Large Scale DSO does not support RSM Service running with ’system login’ credentials.

On each machine of the cluster, 'desktopjob' application is registered with RSM service using the command shown below:

Windows: <installation-directory>/<platform> desktopjob.exe -regserver

Linux: <installation-directory>/<platform>desktopjob -regserver

Note: Detailed cluster configuration instructions are here.

No extra configuration is needed.
