SET NODE

This statement defines a logical set of resources to be used by either requester (client)

processes or server processes. Attributes set by this statement for a given NODE object

are used as default settings for all SERVER and TCP processes associated with that

NODE object. Use this statement before using the ADD NODE

statement.

CPUS (cpu[:weight] [ , cpu[:weight] ]...)

specifies how the Pathway/XM environment is to balance the load of processes

among CPUs when creating processes. You must specify a minimum of two CPUs.

cpu

is the number of a CPU to be used by this NODE object for executing client or

server processes. Valid values are from 0 through 15.

weight

is the percentage of processes that can be executed in this CPU relative to other

CPUs defined for the NODE object. Valid values are 0 through 100.

The sum of the CPU weights for all CPUs defined for this NODE object must

add up to 100.

If you omit this attribute, PXMCFG evenly distributes processes across all

specified CPUs.

Processes are assigned in numeric CPU order (of the CPUs specified) according to

the relative weights assigned to each CPU. Two or more NODE objects can specify

the same set of CPUs.

SET NODE node-attribute [ , node-attribute ] ...

node-attribute is:
