[Eeglablist] Amica13 only using 2 (of 6) Xeon cores on 64 bit Linux (CentOS 6.5)

Hi Ole,

The parameter "maxthreads" limits it to 2 by default. Try setting this to 6, either as matlab keyword, or in a .param file.

this appears to hold on true when running one Matlab session or two in
parallel: 4 of 6 cores are always idle. Unfortunately, Matlab is R2013b.

Does somebody have an idea, why that is?
