The computing lab is equipped with 10 terminals that can log in to Math. Use Math for any application that is not computation intensive (i.e., any application where the results appear in less than a minute or so). Use one of the other servers for more computation intensive applications. Other available servers include xmath, opt4, kharybdis, skylla and godzilla. These are available by first logging into the math server then by using ssh to connect to the desired machine. For example to connect to skylla type:
ssh skyllaTo disconnect and return to math enter:
exitYou can avoid the need for entering a password when connecting to any of these by running the script while connected to math:
ssh_passTo get detailed processor (speed) information connect to the machine and enter:
cat /proc/cpuinfoTo get detailed memory information connect to the machine and enter:
cat /proc/meminfoTo find out how busy the machine you are connected to is enter:
uptimeMath, P4, kharybdis and skylla have standard Redhat software distribution, including GNU compilers (gcc, g77) and TeX. Currently installed software on Math includes the following. Some applications (including matlab) are available also on other servers.
Start from the command line as pgcc, pgf77, pgf90, or pghpf.
General Algebraic Modeling System (GAMS) is a high-level modeling system
for mathematical programming problems. Start by typing gams [filename].
A computational discrete algebra program. Start by typing gap at the
command prompt. Can be exited with Ctrl d.
