“Pascal.valpo.edu”

In 2017 NVIDIA’s Educator GPU Grant program made specialized hardware available to several groups at the University.  Two cards, one directly given by NVIDIA to CIS and one provided by the same program and generously transferred from Electrical and Computer Engineering, were combined with assets provided by centralized IT and Steve Vittitoe, a local University benefactor. This collection allowed students and staff to build a new specialized server named pascal.valpo.edu.

It provides MST/CIS faculty and other collaborators with a locally administered asset for complex numerical work.

Particular thanks to Charles Morris, the first principal student sysadmin, who helped build the system.

 

“The Mathematicians”

A quartet of additional machines was brought online in stages beginning in Spring 2019, all running GNU/Linux Ubuntu 18.04.

These are:

  • euler.valpo.edu (AMD Ryzen 5 1600X @ 3.60 GHz / 32 GB RAM; GEFORCE GTX 1060)
  • fermat.valpo.edu (Intel Core i3-6100 2-Core @ 3.70GHz /  24 GB RAM; GEFORCE GTX 1060)
  • noether.valpo.edu (Intel Celeron G3930 2-Core @ 2.90GHz / 16 GB RAM; GEFORCE GTX 1060)
  • mandelbrot.valpo.edu (Intel Core i5-4570 4-Core @ 3.20GHz / 32 GB RAM; GEFORCE GTX 660)

A private network links the systems via secondary ethernet cards.  An NFS mount (/mnt/sharedFiles) is provided by noether to the other systems over that private network.
