coNCePTuaL 0.8.1

coNCePTuaL software is a tool designed to facilitate rapidly generating programs that measure the performance and/or test the correctness of networks and network protocol layers. coNCePTuaL centers around a simple, domain-specific progamming-language; a few lines of coNCePTuaL code can produce programs that would take significantly more effort to write in a conventional programming language. One of coNCePTuaLs goals is to raise network benchmarking from an art to a science. To that end, coNCePTuaL programs log not only measurement data but also a wealth of information about the experimental setup, making it easy for someone else to reproduce your performance tests. Exemple numreps is "Number of repetitions" and comes from "--reps" or "-r" with default 100. For numreps repetitions plus 2 warmup repetitions { task 0 resets its counters then task 0 sends a 1 megabyte message to task 1 then task 1 sends a 1 megabyte message to task 0 then task 0 logs elapsed_usecs/2 as "One-way latency (us)" and the median of (total_bytes/elapsed_usecs)*1E6/1M as "Bandwidth (MB/s)" } The data is stored in an easy-to-parse comma-separated value (CSV) format with the first row of column headers taken right from the program. The second row of headers indicates how the data in each column were aggregated. Whats important, however, is all of the other information in the log file. coNCePTuaL log files are intended to function as a laboratory notebook, including not only the results of an experiment but also a precise description of the setup that led to those results. How many processors are in my system? How fast are they? What compiler and compiler options were used to compile simple? What command-line parameters were passed to the program? Its all in the log file. The log files also lists the complete program source code so theres no ambiguity about what was measured. You can look at a coNCePTuaL log file a year in the future and still know exactly what the measurements represent�a lot more useful than a performance test which spits out only 397.2 and requires you to recall what that refers to. Whats New in This Release: - pciutils is used (if available) to automatically log the make and model of every network interface that resides on the PCI bus. - Debian users can now run "make dpkg" from the coNCePTuaL build directory to generate a custom Debian package for their system..
