The aim of the project was to implement software which would stress test the memory subsystem of x86 based hardware for Nokia Siemens Networks (NSN). The software was to be used in the validation process of memory components during hardware development. NSN used a number of software tools during this process. However, none met all their requirements and a custom piece of software was required.

NSN produced a detailed requirements specification which formed the basis of the project. The requirements left the implementation method open to the developer. After analysing the requirements document, a feasibility study was undertaken to determine the most fitting method of implementation. The feasibility study involved detailed discussions with senior engineers and architects within both the hardware and software fields at NSN. The study concluded that a Linux kernel module met the criteria best.

The software was successfully implemented as a kernel module and met the majority of the requirements set by NSN. The software is currently in use at NSN and is being actively updated and maintained.

Memory testing software within the Linux kernel has not been implemented previously due to a number of risk factors. However, this implementation demonstrated that it can be achieved successfully. The software has the possibility to be extended for other memory testing purposes in the future.
