-- [ Picked text/plain from multipart/alternative ] Thanks for the stats, handy to know someone else got about that. I don't have any none used HT setups atm to try it on without people screaming :).

I did try it on a single cpu none ht though out of interest just to see the behaviour (as only one we have spare to load cpu atm), and I couldn't get it to switch out of 50/50 either, and it didn't seem to take notice of nice (in top it even said same nice which is weird). So basically wondering if that problem is a problem with prime rather than HT? Is it possible for you to try it on a single cpu/virtual cpu setup and see if its the same? Just then isolates the behaviour out of a ht system.

Re: [hlds_linux] Hyperthreading to do or not

Re: [hlds_linux] Hyperthreading to do or not
-- [ Picked text/plain from multipart/alternative ] There's a couple of different top versions/outputs depending on dist/version so be a bit wary. I've seen a couple where the max was 50% or 100% depending on which one. First thing I tend to do is run something like prime95 or something else that will max a virtual cpu and see what it shows. That will give a base 100% virtual cpu usage line for you to play around and check what makes sense thereafter. Be also wary about dividing cpu usage / 2, as whichever way you look at it, it doesn't really work like that. If its a later version of top and you hit 1 it will show separate cpu states which you may find more useful, and is per virtual cpu. I'm thinking that chances are it will still show 14% (as said there's a couple of different tops, so I don't want to say which for sure), and in reality you are using 14% of a real cpu, but you have some spare processing time depending on what else is running. Typically you won't get much past an extra 10/15%, probably be even less with gameservers. Main thing is not to think of each virtual processor as a full cpu, even though either one can run at 100% in a sense, but not both at the same time, other things are happening.

Re: [hlds_linux] Hyperthreading to do or not
-- [ Picked text/plain from multipart/alternative ] It isn't 50% of a cpu, its 50% of 2 virtual cpu's (per cpu, extend to multiple cpu setups), just some think its 50% as it can look like that, you can't count one virtual cpu as one normal cpu. This is where the whole thing gets messy and you hear wildly varying stories. Most people tend to turn it off with valve games, if you want to play safe or do it as a one off, I'd suggest turning it off. We have ht turned on and have no problems, but if we had more large slot high tick cs/css we'd probably turn it off. Best bet if possible is to try both and see, or play safe with it off.

RE: [hlds_linux] Hyperthreading and DoD:Source
HT is a hardware function = hyperthreading, and your proccessor needs to support it. You can only properly turn it on and off via the BIOS. It is also possible to enable/disable HT in linux but it is advised to do it via the BIOS and seeing as both methods require a restart I would go for the BIOS method. Check your motherboard's manual to see how to access the BIOS and to enable/disable HT if yor system supports it Nic From: Vapok [EMAIL PROTECTED] Reply-To: hlds_linux@list.valvesoftware.com To: hlds_linux@list.valvesoftware.com Subject: RE: [hlds_linux] Hyperthreading and DoD:Source Date: Wed, 12 Oct 2005 09:10:12 -0500 Noob question: How do you turn HT on in DoD: Source?

[hlds_linux] Hyperthreading and DoD:Source
Hi I have had a DoD:S server running on Linux Fedora 3 64 on a dual xeon box (dell poweredge sc1425) since shortly after the game was released. While running a default server with 32 slots the server lags out with one of the virtual cpu's maxing out. It seems to run fine with 24 slots. I read somewhere that this is caused by the hyperthreading on the box and the only way to solve this is to turn hyperthreading off. My question is - is this true? Will I gain a 32 slot (hopefully many more slots) without the cpu maxing by turning hyperthreading off? Or is there a way to make the OS do this? Or is there a fix on its way? I dont live close to the box (amsterdam--london) so a quick bus journey to play with the BIOS is not really possible. Any and all help will be highly appreciated! This mailinglist has already helped me out a lot and I hope it will continue!!

Re: [hlds_linux] Hyperthreading and DoD:Source
From what I've seen, and other can probably comment in more detail, hyperthreading can lag a server and we've seen many posts to the list asking about this. I would recommend searching the list archieve. That being said, your lag can also be caused by the server config itself. We have serveral servers that support and are running hyperthreading, but most are AMD processors so I might be way off, but here's what I've seen. I have several machines that run 18-24 players w/o lag. If I take the same config and change the maxplayer value to 26-32 people complain of lag, choke, etc. So, I would recommend tweaking your config for 32 players (sv_maxrate, updaterate, tic_rate/tickrate, pingboost, etc.) prior to disabling hyperthreading support. Feel free to email me at [EMAIL PROTECTED] for info on DOD:S and DOD server configs or just reply here. Also, check for our DOD:S threads from about a week ago. A few of us posted our DOD:S configs and startup options.

Re: [hlds_linux] Hyperthreading and DoD:Source
I'm assuming that you haven't set the tickrate to 33 and your leaving it to its own devices (which will churn away at 66) if that's the case you have 2 choices. 1.) Set -tickrate 33 in the start line OR 2.) Turn off hyperthreading. Is it not possible for you to get your ISP / Datacentre staff to do the work on your behalf?

Re: [hlds_linux] Hyperthreading and DoD:Source
Sorry I should have said! we have a dual xeon 2.8 (2 x cpu's) with 2 gig ram also we do run multiple servers and total cpu usage is around 50%. The 32 dods maxes out 1/2 of 2.8 so by turning off HT i could gain full usage of 2.8 for the 32 player server (possibly 40 slots) and leave the other games in place. At least that is what I hope to achieve!

Now it could well be there is a specific valve issue with some setups where ht causes problems for their servers which by the sounds of it some seem to get (in which case valve should look into it), but I haven't experienced it so its possible they may not do also, and as I said on a none ht server, a 32 slot dod:s server eats up cpu like I eat pies. If the poster has a 2.4G dual xeon for example I would expect them to be maxed out whatever and would say 24 slots is the way to go, if a 3.8 then I would say yes something is amiss.
