Introduction
Two new computing nodes are now available for use by the
general CS population. They are csa2.bu.edu and csa3.bu.edu.
Both systems are IBM xSeries 365 server with four 2.5GHz
Intel Xeon CPUs and 16GB of RAM. They are running BU
Linux 4.0 (aka Fedora Core 2).
Users
are encouraged to switch over to using csa2.bu.edu and csa3.bu.edu
instead of csa.bu.edu. Support for csa.bu.edu has been reduced
and the machine will soon be retired.
Some
important things to note:
- Since
the hardware archetecture and operating system are changing,
programs that were compiled to run on the Sun Solaris
based csa.bu.edu will need to be recompiled to run on
an Intel based Linux.
- Paths
to programs have changed. Please read the section below
to fix your .cshrc and .login files.
The
new csa has most of the standard software packages that
are available with BU Linux/RedHat. These packages include,
but are not limited to:
- GCC
compilers (gcc, g++, etc.)
- Emacs
and XEmacs
- Sun
Java compilers
- teTeX
(a Linux laTeX implementation)
- Perl
- Python
- OpenOffice
(an open sourced MS Office like program)
-
PostgreSQL client
- X-windows
and various managers (Gnome, KDE, etc.)
- Gimp
(an image manipulation program, similar to Adobe Photoshop)
Along
with BU Linux/RedHat software, the following software packages
are available:
- Matlab
- Mathematica
- Adobe
Acrobat Reader
SSH
Keys
Below are the public SSH keys for the two systems:
Older
CS accounts
Users whose accounts were created before September 1999
may have some problems logging into csa2 or csa3 due to
old configuration files. Their .cshrc and .login files may
be specifically configured for a Solaris operating system
environment. These files may not make allowances for other
OSes.
If your
.cshrc or your .login file doesn't have a line similar to:
.cshrc:
| source
/usr/local/dot-files/.cshrc |
.login:
| source
/usr/local/dot-files/.login |
Then
chances are that you are using an older configuration file
and may have problems logging into csa2.bu.edu or csa3.bu.edu.
You can remedy this problem by taking the following steps:
- Login
into csa.bu.edu
- Run
the program:
| /usr/local/bin/convert-conf.sh |
This
program will check to see if a .cshrc.solaris and .login.solaris
file exist in your home directory. If they don't, the program
will rename your existing .cshrc and .login files to .cshrc.solaris
and .login.solaris (respectively). It will then copy over
the generic .cshrc, .cshrc.linux, .login, and .login.linux
files into your home directory.
Your
new .cshrc will run either .cshrc.linux or .cshrc.solaris
depending on which operating system you are using. The same
for the .login file.
