Parallelization Error

Hi,

I'm running a piece of code in the matlapool local configuration, and I get the following error:

The client lost connection to lab 5. This might be due to network problems, or the interactive matlabpool job might have errored. This is causing: java.io.EOFException: EOF while reading from PlainConnection{fSocketChannel=java.nio.channels.SocketChannel[closed], fRemoteInstance=[Process: lab 5]}

The code does not create any issues when a parfor loop is replaced with a for loop. Also, the error is reported midway through execution (so many iterations are computed successfully).

I'd appreciate your help with this.

Thanks! Nikhil

Sounds like a resource is being exhausted during the run.

• Check to see if you are running out of memory (including swap) while the code is being run.
• Check if you are filling up a partition (e.g. /tmp if you are on UNIX), or wherever your TEMP environment variable is on Windows.

Beyond that, do you know if: * This happens only on this machine (have you tried others?) * Are there any interesting entries in the machine's event/system logs around this time?

If that doesn't bear any fruit, you could try posting the code here or putting in a call to support.
