PRESENTER: Dr. Joseph G. Kolibal

Dr. Kolibal presented an overview of three different computer systems that are available for Scientific Computing graduate student use that he is the administrator of. These three computer systems are: PAX, EOS and IRIS. (All of these systems and their resources are described in the WEB pages "pax/kolibal/cs" and "pax/cmi", which Dr. Kolibal referred to.)

Also briefly mentioned was another system that is available for SC graduate student use, i.e., the USM Beowulf Cluster – WIGLAF located in the Polymer Science building and administered by Dr. Ray Seyfarth. The USM Beowulf Cluster – WIGLAF is described in the WEB pages "orca/~seyfarth/wiglaf".

Both PAX and EOS are located in room 114 of the Bobby L. Chain Technology Building. IRIS is located in room 205 of Southern Hall. PAX and IRIS are INTEL Pentium chip, 32 bit architecture machines, while EOS is a DEC Alpha chip, 64 bit architecture machine. In the WEB page "pax/kolibal/cs", the megabytes of memory, the gigabytes of hard disk, the specific printer used, etc. are listed

All three of these systems are Unix based systems. For example, PAX and IRIS are using the Red Hat LINUX Version 5.2 operating system, while EOS is using the Red Hat LINUX Version 5.1 operating system.

All three systems have the C, C++ and FORTRAN 77 compilers. They also have postscript and Tex, LaTex and AMSTex document processing support. See the WEB page "pax/cmi" for a description of how to use Tex, LaTex and AMSTex.

The services across the three systems differ somewhat however. PAX has WWW services, as well as those available on the TEC 114 Server. EOS has computational backend use services, as well as the egcs compiler, but it has incomplete package support services. IRIS has complete package support and the plotting package, Tecplot. Other plotting packages used on the other two systems are: gnuplot and plotmtv. The symbolic algebra system MAPLE is also available on both PAX and IRIS.

The USM Beowulf Cluster – WIGLAF located in the Polymer Science building and administered by Dr. Ray Seyfarth was briefly mentioned as another system for SC graduate student use. As described in "orca/~seyfarth/wiglaf", the USM Beowulf Cluster - Wiglaf system is a parallel cluster of 32 INTEL Pentium II CPUs using the Fast Ethernet LAN protocol for inter-processor communication.

The USM Beowulf Cluster – WIGLAF is thoroughly described in Dr. Ray Seyfarth’s WEB pages "orca/~seyfarth/wiglaf". See Dr. Seyfarth’s WEB page for more details.
