We are going to explain the procedure to execute a parallel simulation of a model using COMSOL Multiphysics in the Windows HPC cluster Ben Arabí.

We start checking Show More Options.

Then we introduce a component Cluster Computing by clicking the right mouse button on the study.

We configure the Cluster Computing component with the following parameters:

• Cluster type: HPCS 2008
• Scheduler: winhn.fpcmur.local
• Number of nodes: user selectable
• Directory: \\polyserv\scratch\comsol\username
  Replace username with our user name
  The space \\polyserv\scratch is mapped to the S: drive of the visualization node. unidad S:
• Activate the Specify external process directory path with the same directory.

We choose the Compute opiton to start the model execution:

We wait untel the execution ends to obtain the results. In the Log tab we can check the running status:

When execution ends, the results are not automatically incorporated into the current project, instead we have to check them manually from the scratch space indicated:

1. Close the current project.
2. Open a Windows Explorer and go to the next locaton: \\polyserv\scratch\comsol\username or S:\comsol\username
3. There we have a document named batchmodel.mph where we have the results.
4. Before opening, we move it to the folder where we want to save the datas.

IMPORTANT NOTE: We strongly recommend to delete the content of the folder selected as work shared space (scratch).
