I have been attempting to enable a parallel pool with multiple workers on my local machine. The parallel pool launches normally with 12 workers, but I encounter an error when I try to increase the number to 32. Here are some reference details: Local hardware configuration: CPU(s) = 336, available memory = 694GB MATLAB version: matlab2023b The error message for the 32 workers Parallel pool test is as follows:
Error Report: Failed to initialize the interactive session.
Caused by: Error using parallel.internal.pool.AbstractInteractiveClient>iThrowIfBadParallelJobStatus The interactive communicating job failed with no message.
Interactive client bound to URL: tcp://tcpnodelay=localhost:27370/protocol/catapult and port 27370 Session failed to start when creating InteractiveClient. Error: Error using parallel.internal.pool.AbstractInteractiveClient>iThrowWithCause Failed to initialize the interactive session.
Has anyone encountered a similar issue? I believe that local hardware resources should not be a limiting factor for utilizing more workers, but why am I unable to use more than 12 workers?I have been attempting to enable a parallel pool with multiple workers on my local machine.
