Coral is a heterogeneous cluster built in three phases.
Our high performance network is a full bandwidth Giganet cLAN connecting these 32 dual CPU nodes. 1.5b7-2tv and Giganet cLAN drivers version 1.3.0 during initial tests, then added TCP tests over Fast Ethernet. Although a VIA device for LAM is under development , it is currently limited to 3-4 processes and lacks SMP support. We also applied our Linux TCP patches to improve TCP performance of our Red Hat 6.2 Linux kernel 2.2.16-3. We also tested local communication between two processes on a dual CPU phase 3 node.
