Parallel Computing for LQCD
Parallel Computing for LQCD
- Two dedicated machines (APE/Quadrics) for 5 international projects
- QH2 with 256 nodes, 12.5 Gflop/s peak, 4GB main memory
- QH4 with 512 nodes, 25 Gflop/s, 2GB
(upgraded last month from a 256 nodes machine)
- Availability during last year: 98 percent, usage: 93 percent
- Applications typically running with 30..70 percent of peak speed
