Explain how to explain the data on the official website of spec cpu2006
http://www.spec.org/cpu2006/results/cpu2006.html #SPECfp_rate There are various models of cpu test results on this link, I want
to know the top
| CINT2006 | CFP2006 | CINT2006 Rates | CFP2006 Rates |
that CINT2006 and Is there any difference between CINT2006 Rates?
参考技术AQ15. What is the difference between a "rate" and a "speed" metric?
There are several different ways to measure computer performance. One way is to measure how fast the computer completes a single task; this is a speed measure. Another way is to measure how many tasks a computer can accomplish in a certain amount of time; this is called a throughput, capacity or rate measure.
The SPECspeed metrics (e.g., SPECint2006) are used for comparing the ability of a computer to complete single tasks.
The SPECrate metrics (e.g., SPECint_rate2006) measure the throughput or rate of a machine carrying out a number of tasks.
For the SPECrate metrics, multiple copies of the benchmarks are run simultaneously. Typically, the number of copies is the same as the number of CPUs on the machine, but this is not a requirement. For example, it would be perfectly acceptable to run 63 copies of the benchmarks on a 64-CPU machine (thereby leaving one CPU free to handle system overhead).
Note: a speed run which uses a parallelizing compiler to distribute one copy of a benchmark over multiple CPUs is still a speed run, and uses the SPECspeed metrics. You can identify such runs by the field "Auto Parallel". Refer to technology BQ15. What Is the difference between a "rate" and a "speed" metric? There are several different ways to measure computer performance. Reference technology C SPEC is the abbreviation of Standard Performance Evaluation Corporation (Standard Performance Evaluation Corporation). SPEC is a non-profit organization composed of computer manufacturers, system integrators, universities, research institutions, consulting and other companies. The goal of this organization is to establish and maintain a set of standards for evaluating computer systems.
SPEC CPU 2006 is the latest version of the CPU subsystem evaluation software launched by the SPEC organization. In the early years, the industry used its previous version, SPEC CPU 2000. Like SPEC CPU 2000, SPEC CPU 2006 includes two sub-items, CINT2006 and C FP2006. The former is used to measure and compare integer performance, while the latter is used to measure and compare floating-point performance. Some tests were updated and some tests were dropped/added, so the test scores of the two versions are not comparable.
