I have an app (standalone app compiled using MATLAB Compiler) running on machines where MATLAB is not installed. The app uses Parallel Computing Toolbox. Hence, how do I create a "Cluster Profile" programmatically? Are there other ways to do this? Thanks.

Hi Adam
You can make use of the cluster object properties and set them similar to how they will be set using Cluster Profile Manager. Please find the attached documentation links that talk about the same.
Cluster Properties
You can also access specific cluster profiles with the help of following functions.
parallel.clusterProfiles
parallel.exportProfile
parallel.importProfile

Hi Hitesh,
These assume that a profile exist, which is not the case when launching an app on a different machine from where the standalone app was created. I need to be able to create a profile from scratch. What I have done so far is the following workaround,
  • From "Cluster Profile Manager" I exported default "local" profile to local.settings file
  • took the contents and modified some things such as path, num cores/thread,
  • created a function to export this xml file to temp dir upon launch of standalone app
  • import the profile from the file
  • start the pool now.
What I would like to do is to create the cluster 'object' from scratch.

Hey,
The problem is that when you compile your app into a standalone app, then the embedded 'local' profile contains a property indicating where the scheduler stores temp files on harddrive. Now, of course, this is not ok as my client running my app may have different file structure and privileges.
When you start the parallel pool on another machine the process fails as it looks for a path that does not exist.
This is only a problem for deployed apps.

Hello,
Jumping up as I have the same problem. I am trying to run a compiled code into an HPC infrastrucutre that doesn't have MATLAB installed in it. The problem is that, apparently, parpool() requires some files that are not available when using MCR in the HPC, but where available with a full MATLAB software used for the compilation.
Is there any workaround on this?
