Subject Running UIMA on a cluster
Date Fri, 27 Apr 2012 19:35:35 GMT
Hello,

Is there any best practice documentation out there for running
UIMA/UIMA-AS on a cluster? I have only run single machine instances of
UIMA (mostly through Eclipse) and have not investigated the ability to
perform multiple simultaneous analyses in order to process large document
collections.

It's not clear to me how UIMA would operate in a cluster environment, do
people really do message passing using JMI? I'm guessing this is the case
as I seeing references to MPICH, SGE or other things I am more used to.
I've looked through some of the documentation (including all the Overview
& SDK setup) but am not finding anything helpful. I've also tried googling
but I am not getting much except this:
http://comments.gmane.org/gmane.comp.apache.uima.general/2131 which makes
me think it is possible.

Currently with my level of confusion I think it may be best to have
multiple instances of UIMA on a cluster and just submit jobs processing
discrete document sets to our SGE cluster and ignore whatever scaling
features are actually present in UIMA since the document processing I plan
to do is data parallel.
