User Room

The main image processing computers are a mix of Sun Hyper and Ultra-SPARC systems with dual 24 bit displays on switched 100Mb Ethernet. The systems have been configured to be capable of manipulating multispectral images up to 800MB in size.

All systems utilize a mixed 10mb/100mb fully switched ethernet network. The main server is a dual-processor Sun E3000 with approximately 105GB of user storage serving about 300 accounts.

Hardware updates are planned to bring total on-line capacity to 1.6TB.

Hardware available to users includes:

Sun workstations running Solaris
Pentium PCs running Linux and (urk) Microsoft Windows
Macintosh computers.
Flatbed Scanner
Ethernet cables which provide DHCP services for those with portable computers visiting PIRL.

Hardcopy output includes:

Full color high-resolution filmwriter
Legal, letter, wide B size photo-quality dye-sublimation printing.
Inkjet and full duplex high-resolution laser printing.
Large format printing capability (5 feet by n feet) is also available via resource-sharing agreements with another group at LPL.

Data archiving is accomplished via:

Exabyte 8200 and 8505 8mm tape
4mm DDS2 DAT tape
Erasable optical disks
CDROM writer
A 1/2" 9-track tape drive is also available for recovering ancient datasets (this happens more often than you might think).
A 30 tape AIT robotic library with 1.2TB of on-line storage capacity is used to provide 24-hour backup and recovery of all user data.

These resources are available 24 hours a day via a user's room, SSH (versions 1 and 2), anonymous FTP, and a small modem bank providing dial-up networking services. A web server is maintained that includes information on and documentation for available services.

A full repertoire of general software is also maintained. Packages are installed, updated, and maintained as user demand indicates. The Solaris systems are maintained with the latest C, C++, Objective-C, Fortran 77 and Fortran 90, compilers, plus various third party and publicly obtained libraries for software development.

For information on how to do just about anything at PIRL, we suggest you take a look through the PIRL User's Guide first, and if you still have unanswered questions, then e-mail sys@pirlmail.lpl.arizona.edu.
