RHBA-2009:1626 - Bug Fix Advisory

Topic

Updated numactl packages that resolve several issues are now available.

Description

numactl is Simple NUMA policy support. It consists of a numactl program to
run other programs with a specific NUMA policy, and the libnuma library,
which performs allocations with NUMA policy in applications.

These updated numactl packages provide fixes for the following bugs:

• systems with NUMA nodes which were not ordered contiguously caused

numactl to return incorrect and therefore invalid NUMA data. With this
update, numactl shows correct and valid data for systems with NUMA nodes
which are discontiguous in addition to those which are contiguous.
(BZ#491689)

• the "numactl" command possesses an '-H' short option that corresponds to

the long option, '--hardware', which is used to show the inventory of
available nodes on the system. However, numactl did not recognize the short
'-H' option. With this update, numactl now recognizes the '-H' option,
which once again has the same affect as '--hardware'. (BZ#502241)

All users of numactl are advised to upgrade to these updated packages,
which resolve these issues.
