Hi,
I am making some tests with Matlab Parallel Server. I am trying the interactive mode, and I have a function with a parfor. Inside this parfor, there is a mex file. The remote cluster I use has Linux, and the mex files have been created in Linux. The client where I am running Matlab is Windows.
When I try running the file, I get the following error:
Worker unable to find file.
and the name of the mex file. I was reading that the best is to have a networked file share which the worker machines can access. I have placed the mex file in this networked file share, but I get the same error. When I tried running mex files in a parfor directly under Linux, I did not have this problem. Do I need to do something specific when I am running from a Windows client?

I'm assuming you are using parpool? How are you setting the worker's path on the Linux cluster to find the MEX-file? One option is to use pctRunOnAll.

Correct. That's because on your client, the client is looking for and attaching file1.dll. It's unaware that MATLAB will be running on Linux. You're approach to attach the mexa64 is the right way.
