The program +unpacks source code for two loads: hackbench and a Linux kernel +compile, then loops running hackbench and a parallel build of the +Linux kernel. While the loads are running, the cyclictest program is +run to measure realtime performance under load. When the specified run +duration is met, the loads are stopped and cyclictest outputs measured +timer latency values in histogram format, which is analyzed by +rteval. Rteval then writes an XML file to disk with information about +the system (gotten through DMI tables), the raw histogram data +collected during the run and the statistical analysis of the run. + +The rteval source may be pulled from it's git tree on kernel.org: + git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rteval.git + +Rteval requires the following packages to run: + +Python >= 2.4 (and < 3.0) + http://www.python.org/download/ + +python-schedtils + git://git.kernel.org/pub/scm/linux/kernel/git/acme/python-schedutils.git + +python-ethtools + git://git.kernel.org/pub/scm/linux/kernel/git/acme/python-ethtool.git + +libxslt-python + http://xmlsoft.org/XSLT/python.html + +python-dmidecode + http://www.ohloh.net/p/python-dmidecode + +rt-tests + git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git + + +Clark Williams <williams@redhat.com> wrote rteval +David Sommerseth <davids@redhat.com> wrote the XML-RPC and database + logic for handling rteval results. + + + |
