+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.
