Overview
SPECapc for Unigraphics V15 was developed by a user with 20 years
of experience with the application. It is written as a series of UG Macros
that run on Windows NT and UNIX platforms.
The benchmark is based on an aircraft model and covers a wide spectrum
of Unigraphics functionality, including assembly (aircraft in-flight,
cockpit and canopy in shaded and wireframe modes), drafting (cockpit),
NC machining (5-axis toolpath generation), feature options/analysis (mass
properties of a baseplate), solid model creation (baseplate), and mechanisms
(linkage animation of a strut assembly).
Thirty-four (34) subtests are included within SPECapc for Unigraphics
V15. Individual scores are reported for each subtest, both as elapsed
time and as a normalized ratio. The reference system for computing the
normalized ratio is a 500-MHz Pentium III processor with a 440BX chipset,
256-MB PC100 SDRAM, 4-GB 7200-RPM SCSI-II disk, and Diamond FireGL 1 graphics
card. The subtests are categorized into five major groups:
- Graphics 1 -- assembly and mechanisms, eight subtests, 25-percent
weighting
- Graphics 2 -- drafting, four subtests, 25-percent weighting
- CPU-intensive -- 11 subtests, 25-percent weighting
- I/O intensive -- six subtests, 20-percent weighting
- Other operations -- five subtests, five-percent weighting
Each major group is assigned a score derived from the unweighted geometric
mean of the normalized scores of each subtest in the group. An overall
composite is derived from the weighted geometric means of the five major
groups.
