No of Core mismatched with number of CPU

[Dipayan_Nayak]

Hi,

We have cluster R77.30 hosted in open server with 4 cores assigned for the compute. However, in one gateway we are seeing one CPU is functional in top.  fw ctl get int fwlic_num_of_allowed_cores out shows four core is allowed.

Then what could be the issue?

GW#fw ctl get int fwlic_num_of_allowed_cores

fwlic_num_of_allowed_cores = 4

GW# fw ctl affinity -l -r

CPU 0:

All:    eth2 eth3 eth4 eth10 eth11

        fw_0 fw_1 fw_2

        in.geod mpdaemon fwd cprid cpd

Looks like a possible "core crunch" as described on p. 240 of my book, please provide output from the following commands for analysis:

• fwaccel stat
• grep -c ^processor /proc/cpuinfo
• /sbin/cpuinfo
• fw ctl affinity -l -r
• sim affinity -l
• fw ctl multik stat
• tail $FWDIR/conf/fwaffinity.conf

Hi Timothy

[GW]# fwaccel stat
Accelerator Status : off

Accelerator Features Mask : not available
Cryptography Features Mask : not available

[GW]# grep -c ^processor /proc/cpuinfo /sbin/cpuinfo
/proc/cpuinfo:1
/sbin/cpuinfo:0
[GW]# fw ctl affinity -l -r
CPU 0:
All: eth2 eth3 eth4 eth10 eth11
fw_0 fw_1 fw_2

[Expert@MY633-KU3-FW-EXT001:0]# sim affinity -l
Cannot change affinity because only one processor exists
[GW]# fw ctl multik stat

[GW]# tail $FWDIR/conf/fwaffinity.conf
# a. For interfaces, you can also write "default", and the setting would apply to any interface not
# mentioned in the file.
# 3. The desired affinity. Either:
# a. One or more CPU numbers.
# b. "all" - all CPUs are eligible.
# c. "ignore" - do nothing for this entry.
# d. "auto" - use any free CPU. A free CPU is one that doesn't appear in any line in this file,
# and doesn't run a worker thread.
