Hello, ok, I found that cpu pinning was wrong, so I corrected it to be 1:1. The issue with iozone remains the same. The spec is running, however, it runs slower than 1-NUMA case. The corrected XML looks like follows: <cpu mode='host-passthrough'><topology sockets='8' cores='4' threads='1'/><numa><cell cpus='0-3'

LKP framework can guarantee that all the software environment are same on AMD and INTEL platform. INTEL platform always work well, after revert this patch, AMD works well. we tried below commit on AMD. 1) 25de7691a0e27c29c8d783a22373cc265571f5e9: bad 2) a82235843b102202766115e10003c9465a8b83ae: good the error logs(build/CMakeFiles/CMakeError.log) has no difference b/w 1) and 2) on AMD platform

Hello everybody, Thank you Fufu Fang for your quick reply: With tinc version 1.0.35 and the bellow options at 100% CPu load i get about 10 MB/s... PMTU = 1400 PMTUDiscovery = yes #Cipher = none Cipher = chacha20-poly1305 Digest = blake2b512 Tried Cipher = none as well and also got 10MB/s with 100% CPU on one thread the other three available threads are idle. With inc_1.1~pre17-1.1_amd64.deb

hello, i rsynced a kvm vm from one host to another. i start virt-manager and tell virt-manager to use an existing disk. i set cpu to haswell that is on the host. configure before start is set, and i start "begin installation".

Hello everybody, First a big thanks for tinc-vpn I am still using it next to wireguard and openvpn. I am having a setup where the tinc debian appliance is at 100% cpu load doing about 7.5MB/s. Compression = 9 PMTU = 1400 PMTUDiscovery = yes Cipher = aes-128-cbc How can I pick a cipher that is the fasted for my CPU and don't create a CPU bottleneck at 100%. Kind regards, Jelle de Jong

Hi Everyone, I am trying to setup xen3.4.1 FC12(xendom0) on top of FC12 freshly installed. I am using DQ965GF intel mother board having intel VT-x enabled. I have installed everything properly, but xen boot gets stuck at this point, xenbus_probe_init ok ACPI: bus type pci registered PCI: MCFG configuration 0: base e0000000 segment 0 buses 0 - 255 PCI: Not using MMCONFIG. I did few googlings

The first problem is as below: One issue is the files copied to the device but it can't be list on node2, using ls -al the mounted directory. But using debug.ocfs2 on node2, it is ok to list the files copied. After remount of the device on node2, the file can be list. The second is that: Node1 is in the ocfs2 cluster, but using debug.ocfs2, and mounted.ocfs2 -f command, can not list the node1
