## 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.
