Research UNIX Host Upgraded

By Dr. Philip Baczewski, Associate Director of Academic Computing

Sol.acs.unt.edu is a multi-user UNIX host reserved for faculty and graduate student research.  The original Sol was a Solbourne Sun-compatible server which was the first large-scale UNIX system supported on the UNT campus.

That Solbourne hardware was replaced in 1997 with a Sun E5000 server.  Sol is now in its third incarnation after its operation was transferred to a new server platform at the beginning of the SPRING semester.

Sol has been upgraded from version 2.6 to version 8 (2.8) of the Solaris operating system and is now running on a Sun E3500 server.  The E3500 runs at the same processor speed as the "old" Sol, but has a faster internal disk I/O subsystem.  You should notice little or no changes other than those listed here:

• pico is no longer available, however, the pico command still works and invokes the "joe" editor with pico emulation and most control-key commands will work as they did in pico;
  

• those using IMSL will need to replace the source line in their .cshrc file (if any) to read, "source /usr/local/vni/CTT4.0/ctt/bin/cttsetup.csh";
  

• those using IMSL should remove any "setenv LM_LICENSE_FILE" command from their .cshrc (this is now set in the cttsetup file);
  

• those accessing CRSP via FORTRAN programs will need to use the new version of the crspfort script: "/export/data/CRSP/CRSPAccess2.5.1/unt/crspfort".

Getting an account on Sol

Faculty and graduate students may request Sol access by logging into the UNT Account Management page (http://people.unt.edu/manage) and selecting "Request a Sol Account" under "Misc Functions."  Students will need to designate a faculty sponsor who can endorse their access.
