Any possible remedy to run the job

[ajay]

Hi,



Here I am usingSGI Altix 450 server with following configuration:



System Model : ALTIX 450 Server with Itanium2 - 32 cores @1.6 GHz

& 64GB memory


OS : SLES 10 with PPK 5

Installed compliers: 1) Intel C++ 10 Compiler Professional

2) Intel Fortron 10 Compiler Professional



I have been trying to execute the below code on SGI Altix 450 server and getting the error Segmentation fault. Where the code is exactly crashing and the snapshot of the error is appended below. The problem occurs at the segment of the code where the first parallel statement is invoked.



Code:



ajay@aquamarine:~/temp> cat runNGRI

#!/bin/sh

export OMP_NUM_THREADS=8

export F_UFMTENDIAN=big

/home/ajay/temp/magLem37p192n08-v01b-Altx < in-test
