Information on Unix, the Williams CSLab, and More

• The public FreeBSD systems are in TCL 312. You can log into the consoles or remotely using secure shell (ssh). The machine names are pester, zebu, toto, faeroes, baggerbont, dulong, epirus, basuto, bearnaise, hinterwald, pineywoods, and watusi.
• FreeBSD information
• Telnet is bad! Get and use a secure shell client. A couple free ones for windows can be found here and here.
• Our accounts at NCSA are ready. Take a look at the web page about the Origin 2000 at NCSA. To connect to your account, use ssh to host modi4.ncsa.uiuc.edu. To compile a program which uses pthreads, compile with gcc, and add -lpthread to your link line. Run normally. To compile an MPI program, again compile with gcc, but instead add -lmpi to your link line. To run an MPI program interactively, use mpirun much as you do on the FreeBSD systems here.

• High Performance Computing and Communications Glossary from Syracuse University.
