Compute QPI

The compute QPI gives user an overall score for system compute performace.

Summary

The compute QPI are calibrated a ZTE E9000 server as a baseline with score of 2500 points. Higher scores are better, with double the score indicating double the performance. The compute QPI provides three different kinds of scores:

• Workload Scores
• Section Scores
• Compute QPI Scores

Baseline

ZTE E9000 server with an 2 Deca core Intel Xeon CPU processor,128560.0MB Memory.

Workload Scores

Each time a workload is executed QTIP calculates a score based on the computer’s performance compared to the baseline performance.

Section Scores

QTIP uses a number of different tests, or workloads, to measure performance. The workloads are divided into five different sections:

Section	Detail	Indication
Arithmetic	Arithmetic workloads measure integer operations floating point operations and mathematical functions with whetstone and dhrystone instructions.	Software with heavy calculation tasks.
Memory	Memory workloads measure memory transfer performance with RamSpeed test.	Software working with large scale data operation.
DPI	DPI workloads measure deep-packet inspection speed by performing nDPI test.	Software working with network packet analysis relies on DPI performance.
SSL	SSL Performance workloads measure cipher speeds by using the OpenSSL tool.	Software working with cipher large amounts data relies on SSL Performance.

A section score is the geometric mean of all the workload scores for workloads that are part of the section. These scores are useful for determining the performance of the computer in a particular area.

Compute QPI Scores

The compute QPI score is the weighted arithmetic mean of the five section scores. The compute QPI score provides a way to quickly compare performance across different computers and different platforms without getting bogged down in details.
