| a The Pentium 4 CPU is socket 478 ( with "Willamette" core) and operating at 400MHz FSB. |
| b All the memory banks of the Pentium 4 and Alpha systems are filled to accomplish maximum bandwidth due to the dual-channel and switched buses. |
| c PGI: Portland Group Inc. FORTRAN Compiler v3.2-4 for Linux ; IFC: Intel FORTRAN Compiler v5.0.1, Build 010730D for Linux. |
| d SpecFP2000 base/peak values published on the SPEC website (http://www.spec.org). |
| e The marks should be lower than the Compaq DS20E/667MHz system with 8MB of L2 cache. |
