+QTIP Architecture Design
+########################
+
+In Danube, QTIP releases its standalone mode, which is also know as ``solo``:
+
+.. figure:: _assets/standalone.png
+ :alt: QTIP standalone mode
+
+The runner could be launched from CLI (command line interpreter) or API
+(application programming interface) and drives the testing jobs. The generated
+data including raw performance data and testing environment are fed to collector.
+Performance metrics will be parsed from the raw data and used for QPI calculation.
+Then the benchmark report is rendered with the benchmarking results.
+
+The execution can be detailed in the diagram below:

+***************************
+QTIP Command Line Interface
+***************************
+
+Abstract
+########
+
+QTIP consists of different tools(metrics) to benchmark the NFVI. These metrics fall under different NFVI
+subsystems(QPI's) such as compute, storage and network. A plan consists of one or more QPI's, depending upon how
+the end user would want to measure performance. CLI is designed to help the user, execute benchmarks and
+view respective scores.
+
+Framework
+=========
+
+QTIP CLI has been created using the Python package `Click`_, Command Line Interface Creation Kit. It has been
+chosen for number of reasons. It presents the user with a very simple yet powerful API to build complex
+applications. One of the most striking features is command nesting.
+
+As explained, QTIP consists of metrics, QPI's and plans. CLI is designed to provide interface to all
+these components. It is responsible for execution, as well as provide listing and details of each individual
+element making up these components.
+
+Design
+======
+
+CLI's entry point extends Click's built in MultiCommand class object. It provides two methods, which are
+overridden to provide custom configurations.
+
+.. code-block:: python
+
+ class QtipCli(click.MultiCommand):
+
+ def list_commands(self, ctx):
+ rv = []
+ for filename in os.listdir(cmd_folder):
+ if filename.endswith('.py') and \
+ filename.startswith('cmd_'):
+ rv.append(filename[4:-3])
+ rv.sort()
+ return rv
+
+ def get_command(self, ctx, name):
+ try:
+ if sys.version_info[0] == 2:
+ name = name.encode('ascii', 'replace')
+ mod = __import__('qtip.cli.commands.cmd_' + name,
+ None, None, ['cli'])
+ except ImportError:
+ return
+ return mod.cli
+
+Commands and subcommands will then be loaded by the ``get_command`` method above.
+
+Extending the Framework
+=======================
+
+Framework can be easily extended, as per the users requirements. One such example can be to override the builtin
+configurations with user defined ones. These can be written in a file, loaded via a Click Context and passed
+through to all the commands.
+
+.. code-block:: python
+
+ class Context:
+
+ def __init__():
+
+ self.config = ConfigParser.ConfigParser()
+ self.config.read('path/to/configuration_file')
+
+ def get_paths():
+
+ paths = self.config.get('section', 'path')
+ return paths
+
+The above example loads configuration from user defined paths, which then need to be provided to the actual
+command definitions.
+
+.. code-block:: python
+
+ from qtip.cli.entry import Context
+
+ pass_context = click.make_pass_decorator(Context, ensure=False)
+
+ @cli.command('list', help='List the Plans')
+ @pass_context
+ def list(ctx):
+ plans = Plan.list_all(ctx.paths())
+ table = utils.table('Plans', plans)
+ click.echo(table)
+
+.. _Click: http://click.pocoo.org/5/

+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.
