RSM Roles & Terminology
When working with Remote Solve Manager (RSM), there are a few essential terms to understand regarding the components of RSM:
| Term | Definition |
|---|---|
| Job | A processing task submitted from a client application |
| Job Script | Used to perform a processing task |
| Job Template | Used to customize a job |
| Client Machine | Machine where Ansys Workbench and other Ansys applications are installed |
| Client Application | Ansys application that submits jobs to RSM |
| HPC Resource | A system that support High Performance Computing, such as a cluster or cloud environment |
| Node | A single computer |
| Head Node | In a multi-node system, computer responsible for scheduling |
| Execution Node | In a multi-node system, one or more computers responsible for computational work |
| Queue | A list of execution nodes suited for a particular type of job |
| RSM Queue | Queue that contains RSM jobs and maps to appropriate HPC Queue |
| HPC Queue | Queue with one or more execution nodes assigned to it, which are the resources that will be utilized to execute a job |
| HPC Configuration | A set of properties that specify information about an HPC resource |
File Handling
When a job is submitted to RSM from a client application, input files are transferred from the client's working directory to the HPC staging directory, and when the job has finished, output files requested by the client are transferred back to the client application.
The directories are:
| Term | Definition |
|---|---|
| Client Working Directory | Location of job input files on the client machine. The location of this directory is controlled by the client application |
| HPC Staging Directory | A shared directory that all HPC nodes can access |
| HPC Job Directory | Jobs can be run in the HPC staging directory, or in a scratch directory local to the execution node |
File Transfer Methods
RSM utilizes one of the following methods to transfer files from the client to the HPC resource:
- RSM internal socket file transfer
- Operating System file transfer (network share)
- External mechanism (such as SSH)
- No file transfer (client directory is under the HPC staging directory)
