Normalize all section headers
- folder with `index.rst` for parts, using # with overline for heading
- `*.rst` file for chapter, using * with overline for heading
In each *.rst file, use the following token for heading
- =, for sections
- -, for subsections
- ^, for subsubsections
- ", for paragraphs

The suite would be updated for better benchmarks such as Linbench for -the OPNFV E release. - -Getting start with compute QPI ------------------------------- - -Notice: All descriptions are based on QTIP container. - -Inventory File -^^^^^^^^^^^^^^ - -QTIP uses Ansible to trigger benchmark test. Ansible uses an inventory file to -determine what hosts to work against. QTIP can automatically generate a inventory -file via OPNFV installer. Users also can write their own inventory infomation into -``/home/opnfv/qtip/hosts``. This file is just a text file containing a list of host -IP addresses. For example: -:: - - [hosts] - 10.20.0.11 - 10.20.0.12 - -QTIP key Pair -^^^^^^^^^^^^^ - -QTIP use a SSH key pair to connect to remote hosts. When users execute compute QPI, -QTIP will generate a key pair named *QtipKey* under ``/home/opnfv/qtip/`` and pass -public key to remote hosts. - -If environment variable *CI_DEBUG* is set to *true*, users should delete it by -manual. If *CI_DEBUG* is not set or set to *false*, QTIP will delete the key from -remote hosts before the execution ends. Please make sure the key deleted from remote -hosts or it can introduce a security flaw. - -Commands to run compute QPI -^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -In a QTIP container, you can run compute QPI by using QTIP CLI: -:: - - mkdir result - qtip plan run <plan_name> -p $PWD/result - -QTIP generates results in the ``$PWD/result`` directory are listed down under the -timestamp name. - -you can get more details from *userguide/cli.rst*. - -Benchmarks ----------- - -The benchmarks include: - -Dhrystone 2.1 -^^^^^^^^^^^^^ - -Dhrystone is a synthetic benchmark for measuring CPU performance. It uses integer -calculations to evaluate CPU capabilities. Both Single CPU performance is measured -along multi-cpu performance. - - -Dhrystone, however, is a dated benchmark and has some short comings. -Written in C, it is a small program that doesn't test the CPU memory subsystem. -Additionally, dhrystone results could be modified by optimizing the compiler and -insome cases hardware configuration. - -References: http://www.eembc.org/techlit/datasheets/dhrystone_wp.pdf - -Whetstone -^^^^^^^^^ - -Whetstone is a synthetic benchmark to measure CPU floating point operation performance. -Both Single CPU performance is measured along multi-cpu performance. - -Like Dhrystone, Whetstone is a dated benchmark and has short comings. - -References: - -http://www.netlib.org/benchmark/whetstone.c - -OpenSSL Speed -^^^^^^^^^^^^^ - -OpenSSL Speed can be used to benchmark compute performance of a machine. In QTIP, -two OpenSSL Speed benchmarks are incorporated: - -1. RSA signatunes/sec signed by a machine -2. AES 128-bit encryption throughput for a machine for cipher block sizes - -References: - -https://www.openssl.org/docs/manmaster/apps/speed.html - -RAMSpeed -^^^^^^^^ - -RAMSpeed is used to measure a machine's memory perfomace. The problem(array)size is -large enough to ensure Cache Misses so that the main machine memory is used. - -INTmem and FLOATmem benchmarks are executed in 4 different scenarios: - -a. Copy: a(i)=b(i) -b. Add: a(i)=b(i)+c(i) -c. Scale: a(i)=b(i)*d -d. Tniad: a(i)=b(i)+c(i)*d - -INTmem uses integers in these four benchmarks whereas FLOATmem uses floating points -for these benchmarks. - -References: - -http://alasir.com/software/ramspeed/ - -https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W51a7ffcf4dfd_4b40_9d82_446ebc23c550/page/Untangling+memory+access+measurements - -DPI -^^^ - -nDPI is a modified variant of OpenDPI, Open source Deep packet Inspection, that -is maintained by ntop. An example application called *pcapreader* has been developed -and is available for use along nDPI. - -A sample .pcap file is passed to the *pcapreader* application. nDPI classifies traffic -in the pcap file into different categories based on string matching. The *pcapreader* -application provides a throughput number for the rate at which traffic was classified, -indicating a machine's computational performance. The results are run 10 times and an -average is taken for the obtained number. - -*nDPI may provide non consistent results and was added to Brahmaputra for experimental -purposes* - -References: - -http://www.ntop.org/products/deep-packet-inspection/ndpi/ - -http://www.ntop.org/wp-content/uploads/2013/12/nDPI_QuickStartGuide.pdf |
