[mpich-discuss] Clustering

[Svancara, Randall]

I would say at a minimum, you need a dedicated gigabit Ethernet between the two machines, and an operating system that can support MPICH and Gromacs.  Also you will need a compiler to build all the software as well.  Lastly, your cluster will need to support SSH or some way to launch all the MPI daemons on both systems.

I would start by learning how to use MPI Software to run on one node and then work on expanding to a multinode setup.   Also, you might be better served by starting out with one of the many MPI Hello World implementations and starting there as a learning platform and working your way up to more complex programs like Gromacs.  Once you have a fundamental understanding of all the working pieces, you will have a much better user experience.

Thanks,

Randall

Hi,

I have two servers - one is HP Proliant DL580G5 with 32 cores and other is Hp server with 24 cores. I want to cluster these two with 32 nodes one as the master. Finally I need to use the computational powers of both in gromacs (MD simulation software) using mpi. So, what I want to know is how can I cluster them. If any could be help me out in this, it will be of great help...

Regards
