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).

It's a cluster designed for high performance computing using message passing ... can someone suggest a sample? thanks, Rich --- ramprasads <[EMAIL PROTECTED]> wrote: > dear all > > I have implemented OSCAR on my Redhat linux > box,initailly with on node > attached to it > Installation was successful with Network boot , all > the tests > (PBS,MPI,LAM) were > successful asper the documentation, > > /home File system has been mounted on my client > node,thats there on my > server. > can anybody explain me how to use the cluster. > Is there any sample application that I can run to > see the work nature > of Oscar cluster. > Is Oscar a Failover Cluster,How to implement > Failover Cluster using > Oscar > > I am very new to Oscar and to Cluster > Environment,please don't discard > my Query > > reply back > thankx in advance > > ramprasads > > > > ------------------------------------------------------- > This sf.net email is sponsored by: OSDN - Tired of > that same old > cell phone?
