SPECapc Releases New Unigraphics
WARRENTON, Va., April 27, 2000 - SPEC/GPC's Application
Performance Characterization (SPECapc) project group has released
a new benchmark for Unigraphics V15, a leading CAD/CAM/CAE application.
Initial performance results and free downloads of the benchmark
are available on this site.
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 new 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).
"This is a comprehensive benchmark that allows Unigraphics users to
evaluate system performance based on common application functions,"
says George Chaltas of Intel, SPECapc project group chair. "It furthers
our goal of offering a full suite of benchmarking tools addressing major
applications. We encourage cooperation from ISVs, user groups and individuals
in helping us meet this goal."
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
- 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
