Hi,

I can successfully run a parallel job on my desktop that is calling some mex files I have written. I have used the addAttachedFiles command to ensure the processors see the mex files. However when I run this on our supercomputer cluster I get error messages saying the mex files are not visible. Does anyone have any experience with this sort of thing?

Thanks Adam

The attached mex files may not be in the location where the job in the cluster is executing. To get the location of attached files use 'getattachedfilesfolder' function. Refer the below link:
