The construction of the Geronimo cluster was started in 1998. Originally it had two PC clones, a Pentium II 350 Mhz, and a Pentium III 450 Mhz. Later we added five P III 500 Mhz.
Simultaneously, we started to code a FEM program written in C++ based on PETSc. This is called PETSc-FEM and can be found in http://venus.ceride.edu.ar/petscfem
In 1999, we added 7 Pentium III 733 Mhz, and retired the first two processors.
In 2000, we doubled the RAM on the cluster from 64 Mb on the nodes to 128 Mb. The server has always the double of RAM of the nodes.
The cluster is disk-less and the installation followed very closely the Jacek Radajewski and Douglas Eadline
Beowulf Installation and Administration HOWTO
As the cluster was based on the remote NFS root filesystem (via RARP), the GNU/Linux installed was not upgraded until August 2001, when we upgraded to Red-Hat GNU/Linux 7.1. The upgrading required to slightly modify the
script written by Jacek. Details of the upgrading can be found in UpgradingRedHatHowto
