Folks, I am having major performance issue with my Erlang application running on openstack KVM hypervisor and after so many test i found something wrong with my KVM guest CPU Topology This is KVM host - http://paste.openstack.org/show/790120/ This is KVM guest - http://paste.openstack.org/show/790121/ If you carefully observe output of both host and guest you can see guest machine threads has

I've a HP 8000 Elite SFF machine with Intel Core 2 Duo Quad and 16 GB RAM. I wanted to create a LAB environment to try new things (like CentOS 7). I installed CentOS 6.10 64-bit with no problems and everything is running fine. I then went to Server World and followed the instructions to install Desktop and Virtualization. The install went fine but I had errors when I attempted to build

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'

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...

Hi Apologies in advance if I've missed something obvious. I have read the Sweave manual, the first article in R News, looked at the Help pages, googled Sweave and words like loop, output, files, multiple, done much the same on R site search (in case I missed something on Google) and I couldn't find exactly what I'm after. What I'm trying to do ?---------------------- Make

Hi, my doubt is very simple. I'm sure I've seen someone using something like this before, but unfortunatelly my searches in the archives were useless. Well, I have some objects called after a name that has a number attached to it, varying. Let's say I have: > ls poly1 poly2 poly3 poly4 poly5 poly6 ... I would like to access these objects using a for(), in which I could do

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

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
