(c) 2016 ZTE Corp. + + +Compute Suite +============= + +Introduction +------------ + +The QTIP testing suite aims to benchmark the compute components of an OPNFV platform. +Such components include, the CPU performance, the memory performance. +Additionally virtual computing performance provided by the Hypervisor (KVM) installed as part of OPNFV platforms would be benchmarked too. + +The test suite consists of both synthetic and application specific benchmarks to test compute components. + +All the compute benchmarks could be run in 2 scenarios: + +1. 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 |
