Native Compilation example
On compute020, copy openmp_sample.c from /shared/apps/intel/composerxe/Samples/en_US/C++/openmp_samples/ to your home directory
Build the application with the -mmicflag:
> icc -mmic -vec-report3 -openmp openmp_sample.c
Upload the binary to the coprocessor:
> scp a.out mic0:~/a.out
Copy over any shared libraries required by your application, in this case the OpenMP* runtime library:
> scp /shared/apps/intel/composerxe/lib/mic/libiomp5.so mic0:~/libiomp5.so
Connect to the coprocessor with ssh and export the local directory so that the application can find any shared libraries it uses (in this case the OpenMP* runtime library):
> ssh mic0 > export LD_LIBRARY_PATH=/home/roshan
This application may generate a segmentation fault if the stacksize is not set correctly. To modify the stacksize use:
> ulimit -s unlimited
Go to /home/roshan and run a.out:
