MACHINE: Intel Core2 Duo T9600 @ 2.80GHz
COMPILER: gcc 5.3.0 (as shipped with Slackware Linux 14.2)
The times labeled Reference are for ATLAS as installed by the authors.
NAMING ABBREVIATIONS:
kSelMM : selected matmul kernel (may be hand-tuned)
kGenMM : generated matmul kernel
kMM_NT : worst no-copy kernel
kMM_TN : best no-copy kernel
BIG_MM : large GEMM timing (usually N=1600); estimate of asymptotic peak
kMV_N : NoTranspose matvec kernel
kMV_T : Transpose matvec kernel
kGER : GER (rank-1 update) kernel
Kernel routines are not called by the user directly, and their
performance is often somewhat different than the total
algorithm (eg, dGER perf may differ from dkGER)
AFTER A PARTIAL SEARCH, ARCH IDENTIFIED AS Core232SSE3
