>problem with execution of ./ashru.ex
Are you sure that you entered correct name? Might be it should be ./ashru.exe?

Next time, please, provide full command line - analyzing will be much easier.

Yes I got it.

It was the problem with nfs mounting direcotry.

bcos users home folders shared using nfs.

Thanks

I need one question.We are going to purchase intel cluster toolkit .

Before purchasing I need to know wether this support openmp.If it yes ,how can compile and run the program parallel using openmp.

Thanks your help.

Hi Ashraf,

There are 2 different versions of the Intel Cluster Toolkit: Cluster Toolkit and Cluster Toolkit Compiler Edition.

OpenMP and MPI are two absolutely independent techniques. Having Cluster Toolkit you can compile your programs by GNU compilers even if code contains OpenMP directives. Intel Cluster Toolkit Compiler Edition includes Intel compilers and they also supports OpenMP.

Applications which contains both MPI functions and OpenMP directives are called Hybrid applications.
To compile a hybrid application you need to add '-openmp' option to the compiler wrapper ('mpicc -openmp', 'mpiicc -openmp')

To run a hybrid application you need to use either 'mpirun' or 'mpiexec' command. To run OpenMP application you don't need MPI at all - just start your application as any other program.

Regards!
