What is the Remote Solve Manager?

The Remote Solve Manager (RSM) is a The Remote Solve Manager (RSM) is a job queuing system designed specifically for use with the ANSYS suite of solvers

RSM enables jobs to be offloaded from your local machine and distributed to remote compute serversremote compute servers

— Integrated solution, no batch scripts required!

— Setup many design points and distributeSetup many design points and distribute them to multiple compute servers to run in parallel

The RSM architecture allows users to disconnect from a remotely running job and reconnect to download at a later time

Typical RSM Workflow

There are 3 main roles in the RSM hierarchy: There are 3 main roles in the RSM hierarchy:— RSM Client – machine from which jobs are offloaded— Solve Manager – hub that receives jobs from RSM clients and dispatches them

to the available compute serversto the available compute servers— Compute Server – machines on which the jobs are actually run

A given machine can play any combination of the 3 roles A given machine can play any combination of the 3 roles.— A typical RSM implementation is shown below

Configuring RSM

At version 14.5, configuring RSM is simple!— Just follow the RSM Setup Wizard found in:

• Start > All Programs > ANSYS 14.5 > Remote Solve Manager > RSM Setup Wizard 14.5IMPORTANT O Wi d 7 b t RMB Cli k d R Ad i i t t• IMPORTANT: On Windows 7, be sure to RMB Click and Run as Administrator

— Prompts differ depending on the role of the machine in the RSM hierarchy, however the first few steps are always the same

• Configure the Compute Servers first followed by the Solve Managers and finallyConfigure the Compute Servers first, followed by the Solve Managers, and finally the RSM Clients

Otherwise, select the second option. This is the default option and is the more common selectionmore common selection.

Configuring RSM

ANSYS Workbench and RSM must be installed on all machines in the ANSYS Workbench and RSM must be installed on all machines in the RSM layout. Ensure that this is the case and confirm by selecting the check boxes

— RSM is automatically installed along with Workbench— RSM is automatically installed along with Workbench Next, we’ll detail the configuration procedure for each role in the RSM

The RSM Setup Wizard will prompt you to confirm that RSM Services The RSM Setup Wizard will prompt you to confirm that RSM Services have been started on all Compute Servers. Ensure that this is correct before moving forward.

The RSM Setup Wizard will allow you to modify the settings for the Solve The RSM Setup Wizard will allow you to modify the settings for the Solve Manager being configured. These include:

— Job Cleanup PeriodProject Directory— Project Directory

— Compression Threshold To keep the defaults, select the No radio button

These settings can always be modified at a later time— These settings can always be modified at a later time

To add Compute Servers to which the Solve Manager can submit jobs To add Compute Servers to which the Solve Manager can submit jobs, select the “Yes” radio button and then select “Define a new Compute Server”

Enter the Machine Name or IP Address of the Compute Server along with Enter the Machine Name or IP Address of the Compute Server along with a name used to identify the Compute Server in RSM

— The following prompts will then ask you to specify the details of the Compute ServerServer

The next two screens prompt the installer whether the Compute Server is: The next two screens prompt the installer whether the Compute Server is:— Part of a Cluster – select Yes only if the compute server is managed by

Windows HPC, LSF, or PBS— A Linux machine requiring SSHA Linux machine requiring SSH

17


The following screen prompts the user to specify a working directory for The following screen prompts the user to specify a working directory for the Compute Server

— If the Compute Server has one hard drive that is faster than the others, specify its local path (i.e. F:\RSM)its local path (i.e. F:\RSM)

18


The following screen prompts the user to specify the maximum number of The following screen prompts the user to specify the maximum number of jobs that can run at one time on the Compute Server

Confirm the Compute Server settings are correct and then choose wether Confirm the Compute Server settings are correct and then choose wetheror not to add additional Compute Servers (repeat from slide 15)

21


Once the Compute Server details are completed we need to set up the Once the Compute Server details are completed, we need to set up the Queue that will manage them

— The Queue manages the distribution of jobs among the Compute Servers and the availability of resourcesthe availability of resources

22


Define a new Queue to Manage the Compute Servers you have previously Define a new Queue to Manage the Compute Servers you have previously configured

23


Specify a name for the Queue and select the Compute Servers that will be Specify a name for the Queue and select the Compute Servers that will be assigned to the queue

By default RSM will use the current Username and Password to log in to By default, RSM will use the current Username and Password to log in to the Compute Servers when submitting jobs. If this username is able to log in to each Compute Server then no further action is required. Otherwise an alternate account must be set upalternate account must be set up
