Star-P support

[Wingerden, E.J.M. van]

Dear developers,

Buried in the code for freqanalysis_mtmconvol.m	I found a comment about
a possible implementation of parallel data processing using star-P (line
466).
Is this a feature that is under development at the moment? I have some
experience with star-P myself and found that using FieldTrip in
combination with a star-P computing cluster is quite hampered by the
fact that structures cannot be passed as broadcast arguments when the
computations are distributed. 

Have you found ways to circumvent this problem? In my opinion, the
FieldTrip code could greatly benefit from parallel computing when
splitting across channels, or trials even. However, since usually
datasets are split at a high level function while the actual computation
takes place within a low level function, the fact that structs
containing the parameters that are necessary for the computation need to
be passed as arguments between these functions makes it pretty hard to
make them star-P compatible. 

Are you in contact with the star-P developers? I would imagine that they
are very interested in the programming needs of a large user
community/potential customers as we have here.

best regards,

marijn van wingerden
