AIX Version 4 was used with each of these benchmarks. IBM C Set++ for AIX
Version 3.1.2 and AIX XL FORTRAN Version 3.2.2 are the compilers used in these
tests. The preprocessors used in the tests include KAP 2.5. for FORTRAN and
KAP/C 1.4.2 from Kuck & Associates, VAST-2X.03h28 from Pacific Sierra
Research. The preprocessors were purchased separately from these vendors.
SPECint95
: Result is the geometric mean of eight tests that comprise the
CINT95 benchmark suite. All of these are written in C language.
SPECint_base95
: It is the result of the same tests in CINT95 with a maximum of
four compilers flags that must be used in all eight tests.
SPECint_base_rate95
: Geometric average of the eight SPEC rates from the
SPEC integer tests (CINT95) with the restrictive compiler options.
SPECfp95
: Result is the geometric mean of ten tests that comprise the CFP95
benchmark suite. All of these are written in FORTRAN language.
SPECfp_base95
: It is the result of the same tests in CFP95 with a maximum of
four compilers flags that must be used in all ten tests.
SPECfp_base_rate95
: Geometric average of the eight SPEC rates from the
SPEC floating-point tests (CFP95) with the restrictive compiler options.
LINPACK DP
: Double precision, n=100 results with AIX XL FORTRAN compiler
with optimization. Units are megaflops (MFLOPS)
LINPACK TPP
: Toward Peak Performance, n=1000 results with AIX XL
FORTRAN compiler with optimization. Units are megaflops (MFLOPS)
tpm
reflects IBM's estimate of complex commercial transactions per minute.
