Unix operating system. Polygraph has been tested (to various degrees) on FreeBSD, Linux, Solaris, Digital Unix, HPUX, and IRIX.

A C++ compiler. Polygraph uses C++ features that are widely supported. Polygraph does not use STL library. A recent version of g++ should suffice.

Processor, memory, disk, network, and other resource requirements depend on the workload to be used. For most production tests, at least two machines are required (to run Poly-client and Poly-server).

You may not need more than 1024 filedescriptors, but you probably will need more than 256. Be sure your OS can support the limit you need.
