4) -m socket:socket_id:mem::size speciﬁes that the SLM from socket socket_id in the target

vPar be set to size MB. This operation may result in assignment or deletion of SLM. The

-m

option is internally mapped to either a -a

or -d option. The difference in the current memory

size and the speciﬁed memory size is rounded up before the addition or deletion. This may some-

times result in the new memory to be more than the speciﬁed value if

-m is internally mapped to

-a or less than the speciﬁed value if

-m is internally mapped to -d. Refer to the examples above.

Command Examples

If more than one task is speciﬁed in a command, they are processed in the order (left-to-right) in which

they are encountered on the command line. Some tasks will affect the outcome of others. Here is an

example of correct usage, as well as counterexamples within the description.

vparcreate -p my_vp -a cpu::2 -a cpu:::2:4 -a cpu:1/1/0/0 \

-a cpu:1/1/0/1 -a mem::1280 -a io:5/1/0/0/0 -a ioslot:5/1/1

At creation time, before any options are processed, min is equal to

0,asisnum. Assume that the default

max is sufﬁciently high, and that the speciﬁed resources are available for allocation.

-a cpu::2 succeeds because num(2) is within the range of the min and the max.

-a cpu:::2:4 then succeeds because num(2) is still within the required range. Note that if

the two options were reversed the command will return an error due to left-to-right option pro-

cessing, and the desired min would exceed the default num.

Finally, the speciﬁcation of the two CPU-cores at explicit paths

1/1/0/0 and 1/1/0/1 also

succeeds because total CPU-core num is still not greater than max(4).

Table III. Detailed Resource Speciﬁcations

Table III.a. Tasks: -a cpu::num

-a core::num

Explanation Adds num non-SLPs to the vPar’s conﬁguration.

The CPU-cores are drawn from a system wide pool of

available CPU-cores.

Value num: A positive integer

Usage o Total number of CPU-cores <= max

Restrictions o num CPU-cores must exist in the nPartition

o num CPU-cores must be available (not assigned to

any vPar)
