Release Notes
System monitor displays less processor cores when
Hyperthreading is enabled
Description: After booting to SUSE Linux Enterprise Server 12 Service Pack 2 (SLES 12 SP2), the system monitor displays less
number of processors than what is listed in /cat/proc/cpuinfo
Cause:
Libgtop which is part of system monitor has a code that counts the number of processors by copying the content
of /proc/cpuinfo into a 64 k buer and then reads through it, which is inadequate for some hardware (platform
with higher number of processor cores).
Workaround: This issue is xed in the newer version of the libgtop 2_0-10-2.34.0-11.1.x86_64 through the
patchCpu buffer .patch. This patch uses a large buer to read /proc/cpuinfo when required.
