Overview of Aon

Processors:

Our 128 processor Apple cluster is composed of dual 2.0 Ghz G5 processors.

Login node:

eliza.engin.umich.edu.

System Memory:

Each SMP node has main memory of 2GB.

Each CPU has 64K of L1 instruction cache and 32K of data cache. Each CPU's L2 cache has 512K for both data and instructions.

Network:

Full line rate gigabit through our Force10 switch (each node can sustain gigabit speeds regardless of what the other machines are doing).

Myrinet: Currently, we are testing the high-speed low latency myrinet switch on some of the eliza compute nodes.

Storage:

We have 2 Xserve raids, each w/ 1.4 TB capacity. The directory /home is a shared NFS mounted on /home (1.4 TB) .

/tmp is temporary storage local to each machine - use this for bettery performance, rather than working out of /home.

You can also archive your files on our 70TB storage system w/ TSM's archive function.
