You are now using a different library for communications. How much this affects the timing of your program depends on how your program uses the network, and whether it's on the critical path.
This is a new communication library, so if you end up re-running benchmarks
and find it makes a difference in performance, I would be interested to
know if those differences are positive or negative.

Hello again
Well this method works... There is no more ERRNo=104 problem.
But I wish to know how much affect to the timing of the program shall occur
now.
I had previously collected few results without using this option and my
further results using this option could differ upto what extent.
Thanx

You won't see an OutOfMemoryError if the memory problem is reached in the
native portion of the code, not the java portion.
Try adding the argument "-DX10RT_IMPL=JavaSockets" after the x10 command,
and let me know if it makes any difference.

Hello again
Well my code works well with 32 and 64 instances and I am running on a
cluster where the nodes have upto 64Gb memory for utilization.
Also I am not receiving an Out of memory error (which I generally
received when some of my programs used to run out of memory).
This code of mine does not require large memory.
Also I am working with Managed X10.
if some of my programs used to run short of memory

The ERRNO 104 suggests that one or more of your processes is
exiting unexpectedly. The exit might not be due to the number of
threads or network links, but instead due to something else, such
as running out of memory. Have you checked that you have enough
memory to run 128 instances of your program on your machine? Does
it run ok with 32, or 64 instances, and if it does, how much memory
is free? Are you running native or managed X10?

Subject: [X10-users] Regarding ERRNO=104
Hello All
I am trying to execute an X10 program by setting X10_NPLACES=128
while the number of hardware threads I have are 32.
I know best performance can be achieved only when number of
hardware threads and X10_NPLACES are set equal but just for some
analysis I need such an arrangement.
My program is getting crashed by ERRNO=104 problem.
Is there some way to avoid it or some patch file to use.
Thanx
