MATLAB: Do I receive a “could not create” error when validating the local cluster profile

Parallel Computing Toolbox

The validation for my local cluster profile fails with the following error on the Job test stage:

Description:The validation stage encountered a MATLAB exception.

Command Line Output:(none)

Error Report:

Could not create a temporary directory for the attached file archive.

This error is most likely due to a permissions problem related to the folder of the JobStorageLocation. This location varies by OS, but can be found on a given machine by running the following command:

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

Make sure that you have the appropriate permissions to the folder listed. If you do not have permissions to that folder, you can change the folder used by the scheduler via the Cluster Profile Manager:

1) Select the MATLAB 'Parallel' menu

2) Select 'Manage Cluster Profile'

3) Highlight the relevant local profile and click the "Edit" button

4) Enter a folder into the "JobStorageLocation" field

MATLAB: Do “datenum” and “datestr” not give the same date after conversion

The issue happens because "MM" is the format for 'minute' in "datenum".

You can use the lower case "mm" to get the expected output:

>> a = datenum('20101231','YYYYmmDD');
>> b = datestr(a)
b =
      '31-Dec-2010'

MATLAB: Do I receive a ‘permission denied’ error when running validation or opening a parpool using the local scheduler

MATLAB will use the value of the $TMP variable for the location of the temp folder, so you may encounter this error if $TMP isn't set to /tmp. If you do not have permission to write to the path stored in $TMP, then you will not be able to start a parpool.

To determine the folder used by MATLAB, enter the following into the MATLAB command prompt:

>> tempname

If this isn't a folder that you have permission to write to, either change the value of $TMP to a folder you _can _write to, or change the permissions of the folder $TMP is set to.

You can also try the following:

1. Launch MATLAB

2. Go to ‘Manage Cluster Profile’ located in the 'Parallel' drop down options.

3. Select the appropriate Cluster Profile

4. Click ‘Edit’ and the bottom right-hand corner

5. Edit the field for JobStorageLocation to a directory that you have permissions to
