SPEC CPU2000 Benchmark Description File
Benchmark Name
254.gap
Benchmark Author
Martin Schoenert
Benchmark Program General Category
Group theory, interpreter
Benchmark Description
It implements a language and library designed mostly for computing in
groups (GAP is an acronym for Groups, Algorithms and Programming).
Input Description
It has multiple parts, one part of it is the standard gap speed-benchmark,
excercising mostly the combinatorial functions and big number library, then
some test functions for the finite field, permutation group and subgroup
lattice computations, a program comparing two different methods of finding
normalizers in solvable groups and finally a test excercising the collector
for so-called ag-groups, this is a piece where the bulk of the computation
is not done by the interpreter.
Output Description
The output consitsts of the results of these tests.
Programming Language
ANSI C
Known portability issues
The program has, in module system.c, several function prototype definitions
for common Unix system calls. In case that these functions have already
function prototypes defined by the compilation system, the program-supplied
prototypes need to be deactivated to avoid multiple function definitions.
This is done by supplying one or more of the following -D arguments as
compilation switches for the compiler invocation command line:
-DSYS_HAS_SIGNAL_PROTO
-DSYS_HAS_TIME_PROTO
-DSYS_HAS_SIGNAL_PROTO
-DSYS_HAS_ANSI
-DSYS_HAS_MALLOC_PROTO
-DSYS_HAS_CALLOC_PROTO
-DSYS_HAS_READ_PROTO
-DHAS_STDIO_PROTO
-DSYS_HAS_IOCTL_PROTO
-DSYS_HAS_STRING_PROTO
-DSYS_HAS_MEMSET_PROTO
-DSYS_HAS_MISC_PROTO
...
In addition, compilation switches of the form:
-DSYS_IS_xxx
control conditional compilaton for specific operating system dependent
parts. The standard SPEC flag:
-DSPEC_CPU2000_LP64
deals with 64-bit integers and pointers.
Please consult previous submissions and vendor config files if there are
questions with portability.
