Short answer, YES.whatupuppy wrote:Will the IBM slow down the cluster?
Explanation you can measure yourself: Your workers will NEVER achieve 100% utilitzation on HPC problems and large workloads. Your Master will bottleneck in high workload environments.
Why not still use the IBM, but make it a worker. His SCSI drives should be a benefit to certain types of workloads. Its a Win-Win!whatupuppy wrote:Also, what can I do to help?
2 Questions:
- I'm a big IBM fan, but for this requirement, why do you want to make the IBM your master?
- What kinds of work will you have your cluster doing?
This means you are already looking at a very good solution. The faster those cards, the better your cluster can move work and talk to each other.whatupuppy wrote: My friend said he can lend me 6 - 1 gigabit network cards and a 1 - 24 ports 10gb router. I think that should help with communications between the computers.
Also, in your future, consider a SAN with 6 cables to your Cluster heads using 10GB cards to each cluster and you now would be entering the realm of "SuperHuman" HPCs. Couple with Parallel I/O filesystem, and you should be able to fly ... so to speak.
Hope this helps.
P.S. Don't forget my 2 questions, please. I have a personal application I'd like to run in your cluster once you're all set up. It should take about 1 cluster minute.
