Hi,

I used spmd to parallize my script. Unfortunately, I let the parallel pool worker shutdown and lost all the composite variables. If I try to open the those composite variables, I get the following error.

Error using Composite/subsref (line 22)

The Composite is invalid; it may have been saved and loaded, which is not allowed, or the parallel pool has been shut down.

I was wondering if there is any way to access those variables now? I'll make sure to disable IdleTimeout next time.

Unfortunately there is not. The contents of Composite (and distributed arrays) are always left on the workers until you explicitly request them to be brought back to the client.
