Hi, I have tried installing a two node Linux cluster (for computational requirements, but not a high availability cluster).
Environment: 1) OS RHEL 4 release 3 2) Networking Typically TCP/IP for communication 3) Cluster software MPICH2 After completely deploying the mpich2 application I have run a simple c program to chek whether really the program is distributed across the cluster nodes for computation. But I didnot experience this. I found that the time taken is exactly double amount of time as it takes on a standalone machine. My assumptions: 1) If I run execute program on the cluster, the mpich2 application distributes the computation load across the all nodes of the cluster. If so why did my sample program take double time to run? plz correct me if i am in a wrong assumption and suggest an application that meets my requirements (like distribute my application across the cluster nodes for distributed computation) Any suggestions. Thank you Mahen
