Failed to create and submit a parallel job.
This is caused by:
A job submitted to a local scheduler can only
use up to 4 labs

The server has two xenon with 4 core each
How can I open all 8 core?

Which version do you use?
The max number of local workers was increased from 4 to 8 in 2009a.

I use 2008,
Is there anything I can do? upgrade the toolbox or something?

The toolbox version has to match the Matlab version, so you would have
to upgrade both in order to get the change to support 8 local workers.

You could upgrade MATLAB and Parallel Computing Toolbox together, as Walter
suggested, or you could use MATLAB Distributed Computing Server to start a
scheduler other than the local scheduler and start 4 labs on your worker
using that scheduler.
