What version of X10 are you running? JavaSockets is available only in the most recent release (v2.3).

I tried running again and found actually that this issue was coming:
"Unable to load JavaSockets. Forcing single place execution"
Is there any solution for this issue.
Thanx

Hello again
Well I tried using the option, but something strange is occurring..
When I am running on the cluster --- Cluster configuration : Each node of
the cluster has two Intel E5-2670 2.6GHz processors, each processor has
eight cores and each core can make use of (up to) two hardware threads
--- instead of one output I am getting several outputs.
I somehow believe that instead of a single copy of the code, multiple
copies of the program are getting executed. Such a scenario was never
encountered by me earlier.
Thanx

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?

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
