I need a serious workhorse computer for complex simulations
I am running simulations that involve around 6-10 million calculations. My files (10 of them) are each over 500 MBs large (all data and formulas), if that's any indication of the size of the project i'm dealing with. I am currently bogging down a Dell PC with 2.2 Core Duo processor and 2 gigs of RAM. It literally won't run the program in less than one hour.
I have about $6000 in my lab budget for a computer to run this simulation, but i want to make sure i get the most bang for the buck. I priced the following Mac Pro setup at around $6000 (education price). Mac Pro Both Bluetooth 2.0+EDR and AirPort Extreme One 16x SuperDrive Apple Keyboard and Mighty Mouse - U.S. English Accessory kit Two 3.0GHz Quad-Core Intel Xeon Mac OS X - U.S. English 8GB (4 x 2GB) 750GB 7200-rpm Serial ATA 3Gb/s ATI Radeon X1900 XT 512MB (2 x dual-link DVI) Can i beat that system elsewhere for the same price? Please keep in mind that i don't want to use it for daily work... just these, and future, simulations. TIA |

Possibly, but a MacPro 8 core is indeed a beast [img]/images/graemlins/smile.gif[/img]
Your simulations are CPU limited, right? EDIT: And your simulations can run multi-process/multi-threaded, right? |

Re: I need a serious workhorse computer for complex simulations
is there much disk IO once the projects are loaded?

Re: I need a serious workhorse computer for complex simulations
We just bought a new Dell Precision 690 in my lab for CFD simulations. It's essentially the same as that, except we also got a dual 750GB Raid 1 HD array and a 24" LCD monitor for about $6000 (education price).

Try to get 10K RPM drives if you can.

Do 10K RPM 750 GB hird drives even exist?

It's something to look into. If you can get a hard drive big enough for your needs at 10k RPM and if that's faster/more cost-effective than a Raid 1 array at 7200 RPM. Of course, if your problem is CPU limited that won't matter at all anyway.
