A sample application to run on OSCAR is a large matrix solver.

The universal measure of performance for high performance computing is
the number of floating point operation per second (flops) achieved for a
real 64-bit precision matrix LU factorization and solve problem.  This
may be done on a MPI machine using the scalable linear algebra package
ScaLAPACK put together by several institutions including the University
of Knoxville, TN.  The software package can be downloaded from many
different sites, but the main site is:

http://www.netlib.org/scalapack/

Two principle routines in ScaLAPACK, PDGETRF (double precision
factorization) and PDGETRS (double precision solve), are used for this
measure on a 32-bit precision machine.  The speed of the factorization
and solve depends on different parameters used in the problem. There are
test drivers in this software package set up to allow variations for
these many parameters including the size of the matrix factored and the
number of right-hand sides to solve.

For your own comparison, a Cray X-MP in 1987 could factor and solve a
1000x1000 matrix with 1000 right-hand sides at approximately 220 Mflops
(million floating point operations per second).

Thanks,

Paul

Hi,
             I do not have a sample application to run on oscar;
however I can say that oscar is not a failover, or
high availability cluster. It's a cluster designed for
high performance computing using message passing ...
can someone suggest a sample?

thanks, Rich
