Computer Cluster for Turbomachinery
 
Dear All,

I want to simulate the 10 stages of compressor using fluent 6.2 (is there any advantage of using fluent 6.3). for this i have estimated the no of nodes for one components would be around the 0.4 million, therefore in 10 stages this would be 10*2*0.4 = 8 million or so. For this in my estimate i need atleast 40GB RAM (Correct me if i am wrong) and compatable procesor power.

Please some one guide me on how to make cluster which is capable of handling such a huge turbomachinery problem.

Shoud i go for branded available computer cluster or i should use simple computer (due core or AMD) and make cluster my self. in this case what should be network confugration.

can any body tell me the expanses incured for both options.

thanks in advance

You will need about 6 GB of ram. GigE is all you need as a cluster interconnect. As regards cluster choice this depends 100% on your budget. What is your budget?

Best-bang-for-buck option is stringing together commodity desktop machines with a commodity gige switch e.g.

motherboard with decent onboard nic e.g. intel xbx2
Intel q6600 quad core cpu
1-2 gb ddr2-800 ram
power supply
tiny 20 gb hard drive
case
no graphics card

Proper 64 bit OS e.g. centos.

I recommened rocksclusters.org as it gives the cluster a nice front end and is based on centos/rhel i.e. Fluent fully supported.
