similar to: Is Dual CPU machine solution for using Asterisk with other general apps (like home automation, web server, ...) in home environment ?

In Xen''s 3.0 documentation is stated: "f you are running IO intensive tasks, its typically better to dedicate either a hyperthread or whole core to running domain 0, and hence pin other domains so that they can''t use CPU 0." http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03400000000000000000 I am mostly running web servers, so it''s IO

I have some beefy dual-Xeon servers that I will be using for Asterisk VoIP applications (i.e. no Zaptel cards). Using 2.6.11-1.14_FC3smp as the kernel (Fedora Core 3), and currently with Asterisk STABLE. My question is concerning the CPU setup, as I've seen conflicting or out-of-date suggestions: given the above config, should I have hyper-threading turned on or off? Turned on appears like 4

Hi all (and Mr. Dunlap in particular), I have a question about the credit (and ultimately credit2) scheduler that I hope you can help me with. I have read the white paper "Scheduler development update" and as much material on the credit scheduler as I can find, but I am still not completely clear on how I should think about the cap. Example scenario: Server hardware: 2

Changing the vapply() behavior makes sense in principle. I analyzed the CRAN code base using the R parser and found 143 instances of calling vapply with USE.NAMES=FALSE. These would need to be inspected to understand the consequences of the change. For reference: /AzureML/R/datasets.R:226 /BBmisc/R/toRangeStr.R:33 /DBI/R/DBDriver.R:205 /Kmisc/R/str_rev.R:37 /Matrix/R/diagMatrix.R:98

Hi there, I'm currently using CentOS 4.3 (Server edition) in a HP DC 5100 with the IntelR 915GV chipset, powered by a PIV 3.0GHZ. Now I'm facing a problem, with memory. I got myself 4GB of memory, the system bios detects it correctly, but in Linux can only see around 3.5gb memory. With the default kernel-smp (I use hyperthread) or with kernel-hugemem , I have the same results.

Hi, Both vapply() and sapply() support the 'USE.NAMES' argument. According to the man page: USE.NAMES: logical; if ?TRUE? and if ?X? is character, use ?X? as ?names? for the result unless it had names already. But if 'X' has names already and 'USE.NAMES' is FALSE, it's not clear what will happen to the names. Are they going to propagate to the result

Hi, I am trying to figure out why a new machine is running my R script so slowly. The script was developed on a Linux , dual 2.8 xeon processor machine with 4GB ram. On this machine, the script runs in about an hour (it creates lots of multilevel simulations). While running, 100% of a single processor (50% of dual processor) is used consistently during the entire run, about 800 MB of ram is

Hi. I've recently borrowed a SuperMicro 6013P-8 from a vendor for the purposes of testing it to see if FreeBSD and these machines will make a good replacements for our current flock of 11 Netra T1s running solaris. Things are going very well with the tests, with the glaring exception of the following crash: While doing some significant disk operations: du, deleting a different part of the

I just got a spam from telephonydepot (which I invited to spam me, so I guess I have to call it legit marketing :) ), and they have some new device that is meant to be a surveillance camera with audio, but the interface is POE and SIP! A cool idea. Anyone playing with this toy yet? I am trying to wrap my head around how asterisk might fit with the model of this camera being

Hello, My testing machine has 2 quad-core CPU (It supports hyperthreading, but i disable it in BIOS). I uses Xen 4.0.1 as the hypervisor. When I use 8 VMs to conduct a test, CPU affinity of the VMs is very strange. Like this: vm_name vcpu_num cpu_affinity Domain-0 8 any VM1 4 1,3,5,7 VM2 4 1,3,5,7 VM3 4 1,3,5,7 VM4 4

I have an "embarrassingly parallel" routine that I need to run 24000^2/2 times (based on some microarray data). All I really need to do is parallelize a nested for-loop. But I haven't found a clear list of what packages/commands I'd need to do this. I've got a dual quad core xeon system running RHEL5, so if I could use hyperthreading to increase the number of (virtual)

I have some scripts and tools that i have packages up with some documentation that i would like to contribute to the project. They are based on the ntuser_import-1.0.1.tar.gz package in the contributed directory on your FTP server. Basicly its a workaround for syncing unix user id's with an NT domain controller with a samba domain member server that is running on an OS that does not support

Hi All, If you have any interest in home control tied in to your Asterisk installation, things like opening a door for UPS within the 500 ?sec window between when they buzz with your order of 10 TDM400P cards and assorted modules and when they drive away, join us today for a wide-ranging (some might say unfocused) discussion of all things VoIP, home automation, networking both on wires, wireless

Is anyone running any open-source home automation software on CentOS and willing to share experiences?

I've just got bunch of RHEL4 erratas (looks like U2 is out). Looking at the kernel errata (kernel-2.6.9-22.EL), one of the things in list of new features is "Intel dual core support". What does this exactly means? Does it mean if I have dual core pentium processor and use older kernel that it will use only one core, and I need newer kernel to use both cores? Or is it only
