Thanks to everyone who replied -- the Phoronix benchmarks listed by Musaul Karim were quite interesting. I think I'll go with XFS. To answer other questions: it will be quite a "heavy" machine-- dual-socket Nehalems, 24GB RAM, used for a combination of * development (environmental modeling -- large Fortran codes), * GRASS GIS (which uses lots of out-of-core (disk sensitive!) algorithms to deal with the size of problems I have), and * the modeling itself (a typical run may be 100 CPU-hours, generating 70+GB of output). -- Carlie

I'm drooling! what cpu are you going to use? What ram speed? Is this an Intel board? Thanks Cat22

I do land-surface modeling, with typical 5000x8000x8 grid resolution; one run can easily generate 70GB of output (and take 200+ CPU-hours on my current quad-Opteron)... -- Carlie |
