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
- identify applications that are memory, I/O, or CPU
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.
