Hi Krishna

It takes some work to set it up.

**********************
General HPL help
**********************

Here is a starting point:

http://sgowtham.net/blog/

The HPL calculator:

http://hpl-calculator.sourceforge.net/

Some help from AMD:

http://developer.amd.com/documentation/articles/pages/HPCHighPerformanceLinpack.aspx

and some help from Intel:

You need MPI [say MPICH2]:

http://www.mcs.anl.gov/research/projects/mpich2/

a BLAS+LAPACK library [say GoTo or its new incarnation OpenBLAS]:

http://www.tacc.utexas.edu/resources/hpc/
https://github.com/xianyi/OpenBLAS

but you could even use something from yum/rpm/apt-get, or one that
came with your compiler, Intel MKL or AMD ACML
[which may or may not be as fast],

and HPL:

Worth reading about the HPL tuning and FAQ sections:

I hope this helps. Good luck.
