I would say that GPFS and Lustre is more usable than NFS in an HPC environment. You need a parallell file system when the data rates gets higher. But much depends on the I/O-profile of the jobs. /jens -- Jens Larsson, NSC, Linköpings universitet, SE-58183 LINKÖPING, SWEDEN Phone: +46-13-281432, Mobile: +46-709-521432, E-mail: jens at nsc.liu.se GPG/PGP Key: 1024D/C21BB2C7 2001-02-27 Jens Larsson <jens at nsc.liu.se> Key Fingerprint: BAEF 85CF BF1D 7A69 C965 2EE6 C541 D57F C21B B2C7
