To simulate a high load situation, the stressapptest creates the maximum amount of input stress via processor and input and output channels. According to Google, the software generates threads which create memory copies and direct input/output disk reading and writing. The goal is to load up the memory of the system as much as possible in order to effectively test it.
Testing the memory controller and bus interface as opposed to the functionality of storage cells (as in the case of Memtest86). Google alleged that one-fifth of the memory module associated errors of a system can be detected with the stressapptest only, in comparison with other memory diagnosis programs.
The software is available in zipped tar archive form from Google’s project site hosting platform.
