 Product overview

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.
