Unless otherwise indicated for a system, the performance benchmarks were 
conducted using AIX Version 4.2 or Version 4.3. IBM C for AIX Version 
4.1.0.1 and XL Fortran Version 5.1.1.1 were the compilers used in the 
benchmark tests. The preprocessors used in the benchmark tests include 
KAP 3.2 for Fortran and KAP/C 1.4.2 from Kuck & Associates and VAST-2 
Version 4.01X8 from Pacific-Sierra Research. The preprocessors were 
purchased separately from these vendors.

SPEC95 is the forward step in the performance measurement of the core of 
the system. It covers the CPU, caches, memory, and compiler. The programs 
and data sets that make up the suite cannot load entirely into cache, making 
the benchmark more representative of real workloads. SPEC has also 
standardized the compiler settings so that the results for 

 measurements 

are more comparable between suppliers.

SPEC95 is a software benchmark produced by the Standard Performance 
Evaluation Corp. (SPEC), a non-profit group of computer vendors, systems 
integrators, universities, research organizations, publishers, and consultants 
throughout the world. It was designed to provide measures of performance 
for comparing computational-intensive workloads on different computers 
systems.

SPEC95 contains two suites of benchmarks:

Measures and compares computational-intensive integer 

performance

CFP95 

Measures and compares computational-intensive floating point 

performance

The two groups of programs are referred to as component-level benchmark 
suites because they test the core of the system, CPU, caches, memory, and 
compiler, but not the I/O sub-system.

One of the goals of SPEC95 is increased portability; the current offering from 
SPEC is for UNIX only, although the member companies have indicated that 
the benchmark programs are portable to various flavors of UNIX, Windows 
NT, and Open VMS.
