Memory Exerciser

The memory exercisers are labeledx, wherxmemis a number for the exerciser. Multiple exercisers can be active.

The memory exerciser requests as many memory buffers as possible from AIX. 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 correctly, there are no comparison errors. If a nonrecoverable memory error occurs, the system crashes. Recoverable memory errors are logged by the AIX operating system.
