[mpich-discuss] Not able to run HPL Benchmark...

[Albert Spade]

Hello Everybody,

I created a small cluster of 5 machines. One master and 4 compute nodes.
I am having Centos 6.2, mpich2-1.4.1p1, lapack-3.2.1-4.el6.i686,
atlas-3.8.4-1.el6.i686, atlas-devel-3.8.4-1.el6.i686,
blas-devel-3.2.1-4.el6.i686, blas-3.2.1-4.el6.i686 and hpl.

I want to run HPL Benchmark and check the performance of my cluster.
I followed the procedure for single node given on :
http://manyrootsofallevilrants.blogspot.in/2012/04/hpc-beowulf-style-cluster-using-centos.html

But after configuring I am not able to get the desired output. Can somebody
tell me whats wrong with my configuration?

Thanks.

The error I am getting is :
