Failed to start a parallel pool in matlab2015a

Hi, I have tried parpool and it ended as:

-----------------

Error using parpool (line 103)
Failed to start a parallel pool. (For information in addition to the
causing error, validate the profile 'local' in the Cluster Profile
Manager.)

Caused by:
    Error using parallel.internal.pool.InteractiveClient>iThrowWithCause
    (line 667)
    Failed to initialize the interactive session.
        Error using
        parallel.internal.pool.InteractiveClient>iThrowIfBadParallelJobStatus
        (line 768)
        The interactive communicating job failed with no message.

----------

I then tried to validate the profile 'local', and got these details:

I have searched for answered and tried to close my computer firewall but it didn't work. Does anyone know how to solve this problem? Thanks in advance!

I suggest you contact MathWorks technical support to resolve installation problems like this.

Answer 1

[Jason Fice]

I had the same error, and validation results. I contacted Mathworks for help and their suggestion was simple and worked for me. See below for an excerpt from their response to me:

"Thank you for contacting MathWorks Installation and Licensing Support. If you are experiencing issues with opening parpool with the local cluster, you may be having issues with the new local mpiexec implementation. It may not woork on all hardware and software configurations. Try the following command to disable this feature:

distcomp.feature( 'LocalUseMpiexec', false )

If this resolves the issue, add the line to your startup.m file. If you do not have a startup.m, create a new file called startup.m in your MATLAB startup directory and add the above line.

Disabling the local mpiexec will not slow down parpool operation but it may make parpool open more slowly. The decrease in efficacy is negligible"

[Martin Muller]

I just had the same problem.

distcomp.feature( 'LocalUseMpiexec', false )

didn't resolve my issue, but

distcomp.feature( 'LocalUseMpiexec', true )

did. Thanks for this hint. I add it to my startup.m script.

[LeWis RoofRack]

This solved my problem:

distcomp.feature( 'LocalUseMpiexec', false )

Thanks!

[Muahammad Younas]

hi everyone.... i have the same problem using matlab (2015a)... i am not able to solve the problem with above mentioned method... while putting "distcomp.feature( 'LocalUseMpiexec', false )" in "startup.m". Access denied answer is shown to me..... Please help me ...

[Amany Arafa]

Run Matlab as Administrator so you can start parpool

Hi Mathworks,

I have a similar issue (matlab R2018a), but the solution "distcomp.feature( 'LocalUseMpiexec', false )" does not work for me.

Here is the Cluster profile report. Any ideas?

[Star Rats]

This works for my case:

For Windows:

Go to the Start Menu and select Run.

Type in %APPDATA% and press Enter.

For Microsoft Windows Vista:

Type in %APPDATA% in the "Start Search" field above the Start menu and press Enter.

From the Application Data folder, go to MathWorks to MATLAB.

Rename or delete the folder "local_scheduler_data" (when working with MATLAB versions prior to R2012a) or "local_cluster_jobs" (when working with MATLAB R2012a and newer).

Once cleared, try restarting MATLAB.

Thanks a lot Jason Fice and Martin Muller,

This one works........

Answer 4

[shuai li]

I got some other issues. The parallel pool starts normally with small number of workers set. Commands parpool(4) and parpool(6) works well. But when the number of workers increases, command parpool(10) cannot start the pool correctly, and gives the following errors:

Error using parpool (line 113)

Parallel pool failed to start with the following error. For more detailed

information, validate the profile 'local' in the Cluster Profile Manager.

Caused by:

Error using parallel.internal.pool.InteractiveClient>iThrowWithCause

(line 678)

Failed to initialize the interactive session.

Error using

parallel.internal.pool.InteractiveClient>iThrowIfBadParallelJobStatus

(line 792)

The interactive communicating job failed with no message.

Does anyone know how to fix the problem?

Thanks!

[Jordan Makansi]

Hi shuai li, were you able to fix this? I have the same problem on matlab 2020b, and almost exact same error message;

^HError using parallel.Cluster/parpool (line 86)
Parallel pool failed to start with the following error. For more detailed information, create a profile for your cluster and validate the profile in the Cluster Profile Manager.

I tried

and also tried

Still same error.

Were you able to fix it?
