SDSC’s Teraflops Machine
SDSC will acquire a new IBM SP with:
- 144 Nighthawk 8-way SMP nodes
- 1152 Power3 processors running at 222MHz
- 1.023 teraflops peak speed!
The architecture combines SMP technology with MPP technology, enabling scaling to thousands of processors
The programming model will be challenging
- shared memory programming on the nodes (OpenMP)
- message passing programming between the nodes (MPI)
The effort will be worth it; the migration might be slow.
