Recently someone at university gave me a task to create a network for parallel computing. For now i've got two intel chassis, two quad-core processors each, but it will expand with time for sure. I don't have IT degree, I'm only computer enthusiast, and I'm standing in front of following problems:
- What would be the best OS?
- What is the best way to secure such network?
- What would be the better - ldap or nfs - if data will be storaged in separate disk array?
That network will be used by employees of my division for science computations (speed is a very important factor :)). The person who gave me the task advise me to look for CentOS, Beowulf, Kerberos and ldap but i want to know if a better solution exists (maybe more modern one - previous network was build on beowulf).
It needs to be simple and effective (no way?! ;)) and must be easy to expand.
So, should i stick to what was told or should i search for something better? What do you think?
