ScaLAPACK in ASCI Application Amounts To Saving of $1.1M - $5.4M
MP-Quest is a simulation code for materials modeling
- Surface structures at SNL. (Pb-Zn-Ti)
MP-Quest will account for 10% of all cycles on ASCI-Red (presently at 20-30%)
- Symmetric Eigensolver accounts for 25% of cycles in MP-Quest
- Hence 2.5% of Asci Red cycles in MP-Quest's symmetric eigensolver.
ScaLAPACK’s Sym Eig solver is 10x faster than MP-Quest's
- 90% savings in cycles by using ScaLAPACK
ASCI Red cost roughly $50 million
- $50M x 2.5% x 90% = $1.125M today.(may be closer to $5 million)
Right now large problems are too slow because of the eigensolver.
