MATLAB: Do I receive an error regarding that the storage metadata file does not exist or is corrupt

MATLAB Parallel Server

Why do I receive the following error when validating my Parallel Computing Cluster profile or when running a sample job:

Error using distcomp.filestorage/pGetConstructorsFromMetadata (line 22)

The storage metadata file does not exist or is corrupt.

Best Answer

This error generally implies that the user who is submitting the job does not have the necessary permissions to write to the remote job storage location. Please verify that the user who is submitting the job from the MATLAB client has read and write permissions on the cluster headnode location specified in the Parallel Computing profile. This error can also occur if the user does not have read and write permissions to the local job storage location that is specified in the Parallel Computing profile.

MATLAB: Do I need to have a pre-existing “cluster” to use the Distrubuted Computing Toolbox and MATLAB Distributed Computing Engine

This enhancement has been incorporated in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:

The computers used for distributed computing do not require any pre-existing "clustering" software. The MATLAB Distributed Computing Engine (MDCE) enables computers on the same network to act as a cluster, in that tasks are distributed across several independent machines running the MDCE. An actual "cluster," running cluster management software, is not required to use the product.

MATLAB: .mat file corrupt

Try

 load('MOTNL.MAT', '-mat')

Remember, Linux is case-sensitive, so possibly the .MAT is throwing it off.
