Memory Exerciser

The memory exercisers arememxlabeled,where x is a number for the exerciser. Multiple exercisers can be active.

The memory exerciser requests as many memory buffers as possible from the AIX operating system. The exerciser then fills the memory buffers with specified bit patterns, then reads and compares the memory buffers to the specified bit patterns.

On systems with multiple processors

a process is started for each processor. The

free

memory space is split evenly

between

the available processors thus reducing

the

time required to exercise all

of the

memory.

If the system is working properly, there are no compare errors. If a non-recoverable memory error occurs, the system crashes. Recoverable memory errors are logged

by the AIX operating system.
