similar to: P4 processor with Hyperthreading and Asterisk

>but if I disable hyperthreading (noht on the kernel line in lilo/grub) Could the same result could be obtained if hyperthreading is disabled from the BIOS ? Supermicro Motherboards (most Phoneix based) have this option Also, would we see same pops and clicks in a dual CPU box (Zeon) then ?

Are they any issues still with hyperthreading processors, I've read and been told by a few people to make sure its disabled in bios if I want to use * on a hyperthreading machine. Kind Regards, Chris Bond

Dear community, We, a team at IIT Hyderabad are developing an LLVM front end for a networking language called P4 (https://p4.org/). Our work aims to enable LLVM based optimizations for P4. As the P4 language was designed to target many different switch architectures, we feel that P4 can comfortably fit in the LLVM framework where adding targets is more structured. The existing open-source P4

My Dell 2800 Dual 64bit Proc. machine came in with hyperthreading enabled. (they call it virtual processor??) I have been intending for a month to disable it. Tonight, I rebooted, turned it off, and let the system come up. zaptel loaded and asterisk loaded, but both of my t1s were red. (it is a TE411P) /proc/interrupts looked OK, zttest gave OK numbers. I doublechecked all of the files in case

That's the problem we had with Asterisk and HT on a 2.4 Kernel: whenever Asterisk was staying in the RTP stream, and HT was enabled (on a Dell Dual Xeon system), we had choppy audio. After disabling HT, everything was fine again. Nothing measurable, indeed, but you could definitely hear it. So there *must* be something. -Manuel -----Messaggio originale----- Da: Peter Corlett

I just tried to install CentOS (x86_64 4.4 and i386 4.3, not both at once, when I found the 64bit version didn't boot, I tried the 32bit version, same result) on a dual Naconda Xeon system. I get an OOPS just after the IDE info is printed on the screen during boot (this is booting off the CD during the install phase). After mucking about with the bios settings (and many reboots later), I

Hi, I can''t get rid of an annoying domU machines hanging issue with Hyperthreading enabled in my BIOS. Hardware config: IBM x325 series 2 * CPUs Intel Xeon 3.06 Ghz Xen version: 3.0.0 Kernel version: 2.6.12.6 Linux distrib: Debian Sarge 3.1 r1 I run 1 domU machine on my dom0, here is my Xen config: . xen0: /etc/xen/xend-config.sxp : (dom0-num-cpus 0) .

Hi, I have been trying to get Hyperthreading to work in a Windows HVM on Xen 4.1.2 as described in ''xmexample.hvm''. I think I have set it up correctly, but I can''t seem to get it to work. There is not much documentation on it and most topics are from years ago. I''m curious to know to whether this functionality is still supposed to work. I''m aware that

Just gave 3.0 a spin. Had been running 2.0.7 for the past 3 months or so without problems (aside from intermittent failure during live migration). Anyway, 3.0 seems to have an issue with my machine. It starts up the 4 domains that I''ve got defined (was running 6 user domains with 2.0.7, but two of those were running 2.4 kernels which I can''t seem to build with Xen 3.0 yet, and

I have three different live-CD distributions that give me different numbers for the cpu count on this box (Dell P4 2.4GHz). -the Knoppix 3.3 (11-19-03) says 1 processor (no error); -the PHLAK 0.2 distribution say 1 processor (and 1 missing) -the Local Area Security distro says two processors (identicle P4s). Might there be somthing new in 2.0.8 that accounts for this difference. Is there a

Hi, Anyone know how to compile asterisk for a hyperthreaded processor? Thnx

Hi, All: Does the guest OS need to detect hyperthreading? One would think that the hypervisor decides what to schedule on what CPU, and the job of the guest is not to be too smart for its own good. So, my first reaction was to comment detect_ht() altogether. Fedora Core 5 has the code in detect_ht(), though I have no idea what the results of this are on HT CPUs, if they match the reality.

Hi, my video sharing website (politube.org) that I developed with rails, runs on lighttpd/fcgi (I know it is obsolete by now) and is severely under load and regularly blocks because the lighttpd process chews up 50% of RAM (1GB). So now I want to move the system to a new server with 8GB, 64bit , Quad core processor (intel i7 920) but I am not sure if hyperthreading will really do anything better.

I've to setup Asterisk on a Dell PowerEdge 1750 server. Its dual Xeon 3GHz with Hyperthreading. People on this list who have experience with this server please advise me how is the performance of Asterisk on this server, what flavour of linux is good on it etc. Is Hyperthreading going to be a problem or not. I once read somewhere that hyperthreading caused some voice quality problems in

Another question some of you may help me make decisions on. I've been doing some reading that indicates that having HT turned on in this dual xeon machine might actually slow down the computing process rather than speeding it up. I rebooted this a.m., and turned HT off, just prior to my main application run. One thing that might be of note, this application is using OMP for utilizing

To continue here with problems on this compaq v2000 laptop, I put kernel source on a USB disk and plugged it into the v2000. NOTHING IS recognized. I tried to manually mount the disk and nothing either... I thought USB was well established.... I thought trying to recompile the kernel for realtek support might get my networking going... I am stuck??? Jerry -------------- next part

Good morning, The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server. In the case of hyper-threading, should this be the number of cores or the number of threads? For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads. Would I start my worker_processes at 4 or 8? Finally, would the same apply to Nginx worker processes? Many

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, I have two boxes with 2 * Xeon 3.0 Ghz I''ve enabled Hyperthreading in the BIOS. - One box is with Xen 3.0.1 I''ve enabled SMP + SMT in my kernel Xen0 config, and SMP + SMT works perfectly. I can see 4 cpus in my VCPU list for Domain0, and I see also 4 CPUs in the /proc/cpuinfo file. - One box is with Xen 3.0.2 I''ve enabled SMP in my kernel Xen0 config, and SMT has
