-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.
