On Baremetal Machines provisioned by an OPNFV installer (Host machines) -2. On Virtual Machines brought up through OpenStack on an OPNFV platform - -Note: The Compute benchmank suite constains relatively old benchmarks such as dhrystone and whetstone. The suite would be updated for better benchmarks such as Linbench for the OPNFV C release. - -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 |
