PURPOSE of /tools/numatop/Sanity/smoke-test

Description: It generates some NUMA load and checks whether numatop sees it.
|
||||
Author: Michael Petlan <mpetlan@redhat.com>
|
||||
|
||||
The mgen tool has been taken from numatop source package. It should
|
||||
generate some NUMA load, which should be captured by numatop then.
|
||||
|
||||
The test needs at least two NUMA nodes in order to be able to check
|
||||
the RMAs and LMAs (Local and Remote Memory Accesses).
|
||||

|
|||
On some larger systems, memory has non-uniform access times. It is organized
|
||||
in so-called NUMA-nodes. A NUMA node is a part of memory which is accessible
|
||||
faster for some particular subset of processors.

|
||||
|
||||
This machine has two NUMA nodes and 24 processors (they are called CPUs, but
|
||||
that is not very precise). Half of them belongs to NUMA node0 and the second
|
||||
half to node1.
|
||||
|
||||
When a processor accesses data that lies in its NUMA node, it is faster than
|
||||
accessing data from some other node. The local access is called LMA and the
|
||||
remote one is called RMA.
|
||||
|
||||
The NUMATOP tool watches what happens around the NUMA nodes and it sees both
|
||||
LMAs and RMAs. If the machine has only one NUMA node, only LMAs can be seen.
|
||||
|
||||
The test tries to trigger LMAs and check whether NUMATOP registers it. If we
|
||||
have more than one NUMA node, we test RMAs as well.
