DACCT-dynamic ACCess testing of IBM large systems

A description is given of DACCT, a pseudorandom test program generator that tests implicit and explicit storage accesses, and its testing philosophy and programming techniques are discussed. DACCT produces a stressful test environment for a computer system and, by focusing on both explicit and implicit data accesses, finds design problems in several of the testing focus areas. DACCT´s testing methods, error reports, and recreation abilities offered improved detection design problems as compared with the use of an operating system
