Thank you for the reply. Well I tried what you said and understood some aspects. But I observed another peculiar thing which I believe might cause be the reason for throwing ERRNO=104 error. While running I created a simple program, where inside the main function there was nothing just a print statement and return. I again set the number of places to 128 and ran the code. It was interesting to see that even this code threw the error. I actually observed that X10 took a lot of time to set the places and start executing the code when number of places were large, while when the number of places were less say 32 or 64 it loaded up quickly. I believe if X10 is able to start execution then it is not throwing ERRNO=104 error but before that, during the setup phase it throws this error...
