[Eeglablist] About running ica on several machines

[Matthew Ma]

Dear all,

I have been using eeglab for a while for preprocessing stuff, it is very
useful so far. I have been noticing the processing speed of ica was quite
low (I have already used binica and done downsampling of my data). I am
thinking if I can make use of several machines which can be used to do the
preprocessing.

As I noticed, the binica will generate the sphere and weight matrix as a
file, also with the bias file. However, the bias file is always produced
with the same file name, this gives rise to my question. As my work
directory is located in another shared server(I access it using sshfs), I
am wondering if the ica to produce wrong results if I run ica in several
machines simutaneously (due to the same name of bias file...). I know the
easiest solution is to duplicate the work directory to every local
machine...but that seems a little bit stupid to do so.

Looking forward to your reply! Thank you very much.

Best regards,
Matthew
