I've just spent the last month running various benchmarks on IBM's GPFS (General Parallel File System), looking for the optimal way to access it, so these geophysical applications can slurp up their data as fast as possible. Mind you, IBM have changed GPFS a bit after we found some oddities. But where people want the last ounce (milligram?) of performance, they will rewrite their apps to suit the FS/hardware. But, that's not typical I guess. Stephen -- The views expressed above are not those of PGS Tensor.
