+Compute QPI
+***********
+
+The compute QPI gives user an overall score for system compute performace.
+
+Summary
+=======
+
+The compute QPI are calibrated a ZTE `E9000 <http://www.zte.com.cn/global/products/cocloud/cloud_computing/cloud_infrastructure/cloud_hw/429552>`_ 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 |
++=================+==============================================================+==========================================+
+| Integer | Integer workloads measure the integer instruction performace | All app relies on integer |
+| | of host or vm by performing Dhrystone test. | performance |
++-----------------+--------------------------------------------------------------+------------------------------------------+
+| Floating point | Floating point workloads measure the floating pointperfo | Floating point performance is especially |
+| | rmance by performing Whetstone test. | important in video games,digital content |
+| | | creation applications. |
++-----------------+--------------------------------------------------------------+------------------------------------------+
+| Memory | Memory workloads measure memory bandwidth by performing | Software working with cipher large |
+| | RamSpeed test. | amounts data relies on SSL Performace. |
++-----------------+--------------------------------------------------------------+------------------------------------------+
+| DPI | DPI workloads measure deep-packet inspection speed by | Software working with network packet |
+| | performing nDPI test. | anlysis relies on DPI performance. |
++-----------------+--------------------------------------------------------------+------------------------------------------+
+| SSL | SSL Performance workloads measure cipher speeds by | Software working with cipher large |
+| | using the OpenSSL tool. | amounts data relies on SSL Performace |
++-----------------+--------------------------------------------------------------+------------------------------------------+
+
+A section score is the `geometric mean <https://en.wikipedia.org/wiki/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 <https://en.wikipedia.org/wiki/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.
