The NERSC file system differs from that used on the Suns in that
home directories on the Crays have a very small quota even though they
are backed up. The Cray does provide users work disks that have no
quota, but these are every thirty days. CFS should also be used
for files on the Crays that you wish to save indefinately. The Crays
also have `/tmp' disks, which is actually where the work disks are
located (work disks just have their space already organized into user
directories). `/tmp' is used for temporary system files, and all
files in this directory are deleted without backup after about 48
hours. (The `tmp' quota is 491 Mbytes, excluding work
directories. For more information, see `work' and `/tmp' under the
document ezfiles command on the Crays.)
Since the Crays use UNIX, it is an easy matter to access files on the Suns. This comes in especially useful because Often the best way to take advantage of these computing facilities is to access your files on the Suns indirectly from the Crays. On these machines, your home directory is referred to by typing:
