hi
i ran blacs lapack scalapack successfully.
i also executed xspblas1tst
i gave me some out put like this

but my purpose was to find power of my cluster( 3 node cluster)
how can i find that this 3 node cluster power = X flops or Y flops

any routine which can give me flops value of cluster
please help

[kurzak]

One suggestion would be to run the LINPACK Benchmark,
the same used to rank supercomputers on the TOP500 list:
