Reasons to Join the SPECapc Benchmarking Effort

SPECapc Project Committee Rules



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.
