The xmesh utility displays the CPU mesh, which is the interconnection
of CPUs on the next generation hp AlphaServer systems based
on the Alpha EV7 processor. For each CPU, xmesh reports
the utilization for its associated hardware components,
such as the CPU, the ZBox (the memory controller), the
RBox I/O Port, IO7 (ports 0, 1, 2, and 3), the Up and Down
Hoses, and the North, South, East and West interprocessor
ports.
A spectrum of 10 colors indicates levels of utilization
for each hardware component. The colors range from
purple, which indicates low utilization, to red, which
indicates high utilization.
The information obtained from xmesh can be used to
- monitor data flow between CPUs
- determine resource bottlenecks and watch for non-optimal
performance
- identify applications that are memory, I/O, or
CPU intensive
Xmesh can only be run on the new hp AlphaServer systems
running Tru64 UNIX V5.1B.
Note: xmesh does not change system
parameters or configuration.
