The table above shows the measured performance of DWF and asqtad inverters on all the Fermilab LQCD clusters. For qcd and pion, the asqtad numbers were taken on 64-node runs, 14^4 local lattice per node, and the DWF numbers were taken on 64-node runs using Ls=16, averaging the performance of 32x8x8x8 and 32x8x8x12 local lattice runs together. The DWF and asqtad performance figures for kaon use 128-process (32-node) runs, with 4 processes per node, one process per core. The DWF and asqtad performance figures for jpsi use 128-process (16-node) runs, with 8 processes per node, one process per core. The DWF and asqtad performance figures for ds and bc use 128-process (4-node) runs, with 32 processes per node, one process per core.
