- At CMU we are using 12 boxes, each with 4 8-core AMD Opteron Processors (32 cores per box). Each box has 64GB of physical memory. Data are being written to a local RAID disk. Jobs are manage by PBS (torque and maui).
- All 384 cores are reserved for the data challenge for three weeks.
- Start-up Problems
- Large-cluster configuration problems slowed our start. Resolved by tuning PBS parameters to control the rate at which pbs_mom talked to the head node.
- Still battling a scheduler issue. Work-around has been found.
- Running smoothly since ~Tuesday.
- As of 10:30am, 1087 jobs have completed.
