SPECfp95 SPEC component-level benchmark that measures
floating point performance. Result is the geometric
mean of ten tests that comprise the CFP95
benchmark suite. All of these are written in
FORTRAN.
SPECfp_base95 Result of the same tests in CFP95 with a
maximum of four compiler flags that must be used
in all ten tests.
SPECfp_rate95 Geometric average of the ten SPEC rates from
SPEC floating point tests (CFP95).
SPECfp_base_rate95 Geometric average of the ten SPEC rates from the
SPEC floating-point tests (CFP95) with the
restrictive compiler options.
SPECweb96 Maximum number of Hypertext Transfer Protocol
(HTTP) operations per second achieved on the
SPECweb96 benchmark without significant
degradation of response time. The Web server
software is ZEUS v1.1 from Zeus Technology Ltd.
LINPACK SP Single precision, n=100 results with AIX XL
FORTRAN compiler with optimization. Units are
megaflops (MFLOPS).
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). ESSL Version
3.1.1 was used in this test.
Relative on-line transaction processing (ROLTP) is an estimate of commercial
processing performance derived from an IBM analytical model. The model
simulates some of the system’s operations such as CPU, cache, and
memory. However, the model does not simulate disk or network I/O
operations. Although general database and operating systems parameters
are used, the model does not reflect specific databases or AIX version or
releases. Unless otherwise indicated for a system, the model assumes the
use of 32-bit applications. ROLTP is estimated only at the time the system is
introduced, unless otherwise indicated for a system. An IBM RS/6000 Model
250 is the baseline reference system and has a value of 1.0.
