The SPECapc® for Unigraphics V15 benchmark 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 was released on April 27, 2000.
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).
The benchmark includes thirty-four subtests. 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.
