Finding the amount of execution time spent on each processor in a Beowulf cluster
 

Hello Guys, i have downloaded an LU Decomposition program from the following link http://www.cs.nyu.edu/wanghua/course...el/h3/mpi_lu.c and the programming is running very well...The reason for me writing this thread is that can any one help me with getting the time of execution spent on the processors of the nodes connected in the cluster so that it aid me in getting the statistical value from my cluster.
Kindly, help me as i don't know much about MPI Programming, all i want is the amount of time spent on each processor of nodes in the cluster for the above program.

Thank You in Advance :)

I'm not familar with accounting in a cluster, but you will need the usual system accounting installed on all the nodes.

The part I'm not familar with is collating all of the accounting reports from multiple nodes to get the resulting time spent. Using the base tools you would get a process accounting with the information, but each report would be for a node. This works if you don't have too many nodes... but once you pass about 10 it gets to be a real problem...

The reference in http://marc.info/?l=beowulf&m=99248650613978&w=2 is a bit dated, but it is the kind of thing you are looking for.
