iogen is an I/O generator. It forks child processes that each run a mix of reads and writes. The idea is to generate heavily fragmented files to make the hardware suffer as much as possible. This tool has been used to test filesystems, drivers, firmware, and hardware devices. It is by no means meant as a performance measuring tool since it tries to recreate the worst case scenario I/O.
RFDUMP is a GUI to edit the "User Data Fields" on RFID tags and to test if a tag is protected against reading or writing. It implements a real life cookie on RFID tags. The tags that are supported for reading, writing, and editing are ISO 15693, ISO 14443 A, ISO 14443 B, SR176(1,2), Tag-it®, and I-Code®.
Rugg is a hard drive and filesystem harness tool that allows you to test and benchmark drives and filesystems by writing simple to complex scenarios that can mimic the behaviour of real-world applications. Test scenarios can be implemented using Rugg's compact and versatile domain specific language.
The MPI-IO Test is built on top of MPI's I/O calls and is used to gather timing information for reading from and writing to file(s) using a variety of I/O profiles. A data aggregation capability is available and the user can pass down MPI-IO, ROMIO, and file system specific hints. The MPI-IO Test can be used for performance benchmarking and, in some cases, to diagnose problems with file systems or I/O networks.
pretrace is a preload library that allows specified (dynamically linked) applications to always be executed under a debugging environment. pretrace allows you to specify the percentage of invocations which will be traced, to help you "keep an eye" on applications without bringing the machine to its knees.
