1. HPCC Mid-Morning Break
New Node Image

2. Why? (shaw / amd05)
AMD nodes are running SuSE Linux Enterprise Server 9
Unsupported for modern Infiniband, Lustre, commercial software
Old GNU compilers, old libraries, old software
Not 100% compatible for SLES9 -> SLES 10

3. Why? (brody / intel07) Infiniband Update
Faster Infiniband-native Lustre
Faster MPI programs
New Intel Compilers and Libraries
System Update
Stability Fixes

4. Queue / node changes
Single software image everywhere. Compile once, run anywhere*
Route based on node attributes, e.g.
Fat nodes
temp space avail
hardware types

5. What do I need to do? ssh to dev-amd05 or dev-intel07 Recompile
recommended for serial
required for MPI
Run locally on the front-end nodes
Try submitting to the new queue, main
-q main –l nodes=X:ppn=Y:nodetype

6. Node Types amd05 – shaw (amd-xxx) intel07 – brody (scw-xxx)
intel08 – fat nodes (sfn-xxx)
intel09 – Nehalem node
amd09 – fat nodes (afn-xxx)
