can't do parallel computing

Error using matlabpool (line 144) Failed to open matlabpool. (For information in addition to the causing error, validate the profile 'local' in the Cluster Profile Manager.)

Error in feaExtract_parallel (line 28) matlabpool local 12;

Error in run_vtln_all (line 2) feaExtract_parallel( '../list/transform.list', 12);

Caused by: Error using distcomp.interactiveclient/start (line 61) Failed to locate and destroy old interactive jobs. This is caused by: The storage metadata file does not exist or is corrupt

You might need to clear out the "Storage Location" directory on disk - you can find this by executing:

c = parcluster('local')
d = c.JobStorageLocation

I would suggest deleting or renaming that directory - it should be re-created automatically for you.

Hi, I'm running a script in multiple jobs simultaneously in a SLURM cluster. If I delete that directory, would I lose the workers of different jobs? Thanks

I deleted the latest folder and files created in the ../appdata/Roaming/Mathworks/Matlab/local_cluster_jobs/R2017b/ folder. Then ran validate on cluster profile. It ran fine. Now parpool is working

THANK YOU! There were posts all over that I saw and this was the only one that had a solution that worked for me. When I emptied the contents of the ~/.matlab/local_cluster_jogs/r2019b/, I was then able to run parpool without issues.

Thanks! I just had the same issue and this solved it.

Hi Edric, Thanks you very much. It worked.
