similar to: Using multiple CPUs?

An app I run has a feature to allow the user to choose how many CPU's to use to run an optimisation procedure. My system has 8 cores. It can dual boot to Windows 7 and Ubuntu 10.10 64bits. Running the app under Windows 7 and choosing 8 CPU's for optimisation, the speed is greatly improved over using just 1 CPU. But when I use Wine (1.3.23) on Ubuntu and choose 8 CPU's, it seems

I've a dual core system (see /proc/cpuinfo at the end) running CentOS 4.4 (fully up-to-date) and I'm running a PHP script that's parsing files and dumping the results into a database.

I have found a site that list the following (no date in the post, so it may be old): "since all transcoding and calls still go through one core in asterisk, it doesn't make sense to buy a multi-core or hyperthreaded system that will only slow you down" Does that still applies in asterisk 1.2.14/1.4.x ? Or do we have to tweak source code to balance loads (transcoding,etc) between

What is the maximum number of AMD64 cores supported by CentOS 4? The RedHat page https://www.redhat.com/software/rhel/configuration/ suggests that RHEL 4 AS supports up to 8 AMD64/EM64T logical cpus. Is that accurate and does it apply to CentOS 4? I see a few vendors offering boxes with 8 (dual core) CPU sockets. IWILL for one. Thanks, Tony Schreiner Boston College

I've installed CentOS 6.3 on a quad-four box. The model only indicated dual core but CentOS is telling me there are four. This is the first multi-core Linux installation I've had. What is the best way to utilize the multi-core CPUs? I'd like to distribute the load but I'm unsure how to do that. mw -- -- "Lose not thy airspeed, lest the ground rises up and smites

List users, Using Asterisk in an inbound call center environment has led us to pushing the limits of vertical scaling. In order to treat each caller fairly and to utilize our agents as efficiently as possible, it is desirable to configure each client as a single queue. As far as I know, Asterisk's queues cannot be distributed across servers, so the size of the largest queue we service

I've been running tincd on several machines without a problem. I'm now setting up a new intel-type dual-processor machine, with a custom compiled 2.4.9 linux kernel. When I start the daemon: tincd -n vpn -dddddddddd I get the following debug information in in /var/log/messages Aug 27 17:26:49 q tinc.vpn[971]: Process 972 (tinc-up) exited with non-zero status 255 Aug 27 17:26:49 q

I use 3 Ubuntu server 14.04 as KVM guest. Now I run 5 tinc vpns in switch mode. I use the same key for every vpn. Every kvm has connect to the two other servers. I need 5 vpns to have 5 networks connected but seperated. 1 vpn was running fine, but now that I run 5 vpns, my kvm crashes sometimes. Especially when I stop tinc. I used tinc 1.0.26 from repo. Now I tried tinc 1.1 pre, same problem but

Hi All, I have a quick question about the Sieve in Dovecot. I know that this is a plugin so probably it depends on the Dovecot itself but: is it able to use multiple cores/CPUs when doing the filtering? does the filtering for each mail user run on a separate core? Thanks, Pawel

Let’s say, tinc A node server LAN-1(single internet circuit), tinc B node and tinc C node are both serve LAN-2.(two internet circuits) Normally, we can only set tinc A to connect to either B or C, and then the other set as backup. But in some circumstances, we would like to combine the internet pipe of both two circuits, so that the tunnel traffic can have a better bandwidth. If that’s the

Hi there, we're using tinc to mesh together hosts in a public datacenter (instead of using a private VLAN, sort of). So all hosts are reasonably modern; connections are low latency with an available bandwith of around 500Mbit/s or 1Gbit/s (depending on how close they are to each other). Iperf between two nodes directly reports around 940Mbit/s. The CPUs are Intel(R) Core(TM) i7-4770 CPU @

Hi, You mean use the vpn link as active active? What service run for the vpn? If pure tcp load balance, iptables can do these needs.

If you are running Lollipop / Android 5.x on your Nexus 5, then you are probably seeing the same issue I was with it. lollipop seems to change networking quite a bit in that it's using iptables / and `ip rule list` extensively for per-user settings. I think http://www.linux.org/threads/debugging-nat-prerouting-issues-iptables.7136/ is relevant if you see running in to the same issue, it's

I think it's more of a routing issue than anything explicitly blocking it, they use a new 'ip rule list' and per user settings that aren't well documented yet either, but where exactly to point I don't know. I haven't messed with android 5 much yet, it seems not ready enough yet for daily use, there isn't a single snapshot in the cyanogenmod repos, for example. So maybe

Guus: Ok, I accept your challenge. But I am clueless in terms of getting the routing table correct. So each server has a dual identity, both a LAN private identity with a PRIVATE IP address and a WAN public identify with a PUBLIC ip address. And how to have 2 different tun devices show up in the ifconfig -a so that LAN IP address can be assigned to the tun0 and a WAN IP address can be assigned

I've posted this earlier and have not heard much so far. I'd really appreciate any guidance on this as we are about to order new hardware. We are buying Dell workstations with Red Hat Linux and 64-bit Xeon CPUs to run R. We could add a second processor to each system, or buy slightly faster single CPU systems. Is it possible to make a generalized statement as to what kind of performance
