Senthil-
There are a couple ways to make this work; both methods are used widely:
1) Copy the GROMACS cd to somewhere in /home where the nodes can see it, and use cexec to issue the installation commands to the nodes.
2) Export /usr/local from your head node and mount /usr/local across your cluster. You would have to make sure that everything in the current /usr/local on the nodes exists on the server though. On a fresh installation, I think the nodes only contain files from the pbs and pbs_mom rpms, which are already present on the server's /usr/local. (I'm 90% sure of that, you would want to verify) So once you have a single /usr/local set up, it may make installing software across your cluster much easier- the only concern left is performance implications. It just depends on how concerned you are with your jobs accessing the software over the network.

I just installed an oscar cluster with a master and two slave nodes. The installation was successful, I think. Now I have some questions regarding job submissions and software installation. I am used to working with diskless nodes using scyld So any software installation is done only ont the master nodes in that configuration.The particular software I need to use is GROMACS. I installed gromacs in the master node. The binary was installed in /usr/local/bin/ and the file name is mdrun. Now, I created a pbs script file with the command /usr/local/bin/mdrun -options and submitted it to one of the nodes. It comes backs with a file not found. Does this mean that I will have to intall GROMACS on all the server nodes also? I do not have cdroms on the server nodes. If I need to install gromacs ont he server node, how would I do it? Thanks in advance . Any help is appreciated.
