SSSC User's Guide
Any SOI team member may obtain a personal account on the SSSC. Logins are
permitted on any of the machines listed below. There are no individual quotas
on disk space usage nor on processing time, but users should respect both the
system pipeline processing requirements and the needs of the users at the SSSC
itself. Disk working space allocations are described below.
All hosts listed are in the domain stanford.edu.
There are also a number of NCD X-terminals scattered around the SSSC. There
are a few special-purpose machines which should not be used for computing or
logins (general logins may even be disabled on them):
- tarax - a Silicon Graphics (SGI) Power Challenge system
containing 12 R8000 75 MHz MIPS processors and 3 GB of RAM, running
IRIX 6.1, the SGI unix operating system. This is the
pipeline processing system. Public use may be subject to restrictions at times.
- fault - SGI system containing 4 R4400 150 MHz MIPS
processors and 768 MB memory, running IRIX 5.3. This system is the designated
- SGI Workstations - all 200 MHz R4400's with 128 MB memory running
IRIX 5.3 except as noted.
- corona - 250 MHz, running IRIX 6.2
- khors - 256 MB
- rick - 192 MB
- shaman - 250 MHz
- shock - 256 MB
- soieof - 150 MHz, 64 MB
- yeti - 100 MHz R4000, 112 MB
- Sun Workstations - all running SunOS in version noted.
- quiver - SPARC-20, 5.5
- shiver - SPARC-10, 4.1.3
- skaelv - SPARC-10, 4.1.3
- quake - a Digital Equipment (DEC) RISC system 5500 running
- DEC Workstations - all running Ultrix 4.3 except as noted.
- soi - DEC 3100, Ultrix 4.2 : the World Wide Web server
- soidb - SGI R4400, IRIX 5.3
Files on user home directories are backed up daily. There is insufficient
space on the files systems containing these directories to permit the storage
of large working data sets of more than 10's of MB (a few MDI images), and
working space is provided on separate file systems that are not backed up.
Working space is provided in two flavors: scratch space, which is
specifically designated for individual users or groups of users and whose
maintenance is wholly their responsibility; and temporary space, which
is open to all and is subject to automatic purge when usage exceeds certain
Scratch directories are designated /scrX, where X is
a one- or two-digit number. The number of the scratch directory indicates
the machine on which the corresponding file system is mounted. Temporary
directories are designated /tmpX, with the same convention.
Although most of the file systems are cross mounted via nfs, it is
generally preferable to run I/O intensive jobs on the machine on which the
files being accessed are mounted locally, if possible.
Scratch Space Assignments

Working Space Mounts
- 0,1: flytrap
- 40-59: tarax
Requests for system accounts should be directed to Rick Bogart. Scratch disk
space allocations are established and periodically reviewed by a committee
consisting of Jim Aloise, Rick Bogart, Brian Roberts, and Jesper Schou.
