This page stores various results obtained from running the Whetstone benchmark included in this package. Bold text indicates the best result from a given compiler.

Desktops/Personal Computers

Lenovo 3000 J115 (7387-26U)

Released in late 2006 as one of Lenovo's first entries into the United States market under their own name; a fairly average entry-level PC built around AMD's dual-core Athlon 64 X2 microprocessor with 64+64 KiB shared instruction and data caches, 512 KiB per-core second level cache and a 2 GHz clock frequency (model 3800+). All tests are performed under CentOS 7.5.1804 on a system not specifically configured for benchmarking.

All results reflect single-threaded execution. This version of Whetstone does not take any advantage of multi-core processors.
