Hi All,
I have a colleague who wants to parallelize a genetic algorithm written in
Java. I told him that I would evaluate X10 for parallelization for him.
So, the first thing I did was work on updating my tutorial examples from X10
2.1.1 to X10 2.1.2. The only issue I had for most of the codes was to drop the
Void declaration on main, but when I ran my more complicated example
(attached), I got the following errors:
dhudak@opt0003 573%> x10c++ -x10rt mpi -STATIC_CALLS -O -o Driver
DistPrefixSum.x10 Driver.x10
/nfs/07/dhudak/devel/x10/20110525r2/osc-x10/tutorial/DistArrayExamples/DistPrefixSum/DistPrefixSum.x10:81:

onstruction.
5 errors.
This example worked in X10 2.1.1, so I figured that there must have been some
more substantial changes. I have to turn my attention to the GA code, but
figured I would pass this on to the mailing list to see if anyone has seen
something like this before. Let me know.
Thanks,
Dave
