potential problems with dual processor systems?

[protoculture]

Just wondering. I had some glitchy problems back when I had the dual xeon server. Seemed like I did try to do everything to get rid of it... anyway my point was... are dual processor systems more likely to cause problems than single processor systems?

I imagine when UA tests they probably just test for single CPU systems primarily.

So the question for my next computer build will be : single CPU / double CPU system?

No problem here with 4 cards in magma and dual AMD opteron, see system specs below.

 

[Macc]

No probs with 3 cards and err.. Dual core AMD X2 4200 (as I recall, haha - not had to think about it in ages ).

 

[markusone]

No problems here 1 card on a athlon 4400

 

[elram]

but there was a big topic about how multiprocessing and UAD-1 doesnt work together....

no?!

 

[imdrecordings]

Yes... there is still a problem with multi-core processing and UADs. It's not that big of a deal, but still sucks. Mostly Quads.
I say get a multi core CPU.
They're cheap.

Well, if you want to use all 4 of the cores of a quadcore in Reaper, you get CPU spikes and major annoyances with UAD plugins. Same for Sonar from what I can tell. In Reaper you can disable multicore support and UAD plugs work flawlessly. This is a major problem!

I believe the only happy UAD multicore users are either on AMD platforms (slower than Intel) or use Steinberg software (which is not as efficient as other software--i.e. Reaper-- and also has bugs on dual quads).

I just want to use 4 cores of a quadcore and UAD plugs in Reaper without problems but this will not happen until UA updates their drivers. Check the Reaper forum for more info. Help, UA--Please!!!

Hi Scott
What did you mean that "It's not that big of a deal..."?
My next step is a PC upgrade to a Quad core (after having Magnamized my 4 UAD-1 cards in my P4) - do the cards completely not work under a 4Core or is there a workaround (that still benefits from the 4Core environment)?

 

[imdrecordings]

Sorry for being so vague.
Quads are so new, most of the DAW host software out there, is not fully compitable. Programs that can use the resources of a QUAD CPU, have problems with UADs. Like Reaper and SAmplitude. Those are the only 2 programs that have beeen optomized for quad pc's. Steinberg, Sonar, Protools, etc only use 1 or 2 of the cores.

Anywho

I mainly use Steinberg apps and haven't seen a huge problem. C4 or any other Steiny app, doesn't take full advantage of the quad.
Samplitude only takes advantage of the QUAD, when using \"Object based effects\". I don't use \"object based effects\".UADs can't be used as object based effects and O.B.E.'s interfere with my work load.) I think?
Reaper has a special switch for UAD users.
IMO Things haven't quite caught up to the quad yet.

The demo king over at Cakewalk, Brandon Ryan - has a Sonar demo video where he is using an Intel based Octo-core machine (dual quads) - he stated it uses a Tyan Tempest i5000 motherboard (system built by PCAudioLabs).

In the video you can see the meters for each of the 8 cores.

Anyway, I would have to guess based on this that the Quadcore issue is, at the very least, some how UAD/daw-software related.

 

[elram]

so... dual cores-with UAD-1s works fine on Nuendo or not?

and i understand that quad and octo still dont...

am i correct?

I just upgraded my system to an Intel Core2 Quad Q6600 with Asus P5KE MB, Magma4 PCI with 4 UAD-1's using Cubase 4 and so far everything is perfect. It's only been a day so far so I haven't tried pushing it too far but all my previous projects are playing with great stability and incredible processor load decreasing.

Please hurry back...

You'll see a performance increase with the QUAD, but there isn't any software out there that will take full advantage of the QUAD. Go ahead and upgrade. Check the Windows performance meter, when running a session and you'll see what I mean.

HI
that is not correct.

Reaper is fully Multicore (yes issues with UADs)
Samplitude can only use 4 cores and only in performance mode
i dont know of any issues with Samp and UADs
Sonar uses all 8 cores of a dual quad (minor issues with uad)
Cubendo can use 4 fairly well but with 8 it falls on its face.

Xeons can be funky with uads , Single quads no issues.
i have run 4UADs and numerous audio interfaces with Cubendo without ANY issues.
i have also switched out one of the UADS and tossed in a Poco for the fun of it. again no issues

I have clicks an pops using UAD plugs in Sonar. I'm running Vista Ultimate 64 with Sonar 64 and if I take out the UAD plugs, the problem goes away. This with Intel Core2 dual processors. The only thing that makes it tolerable is that exported tracks do not have a problem, it's only during playback that the problem reveals itself.

Not good for clients to hear pops and clicks however.

Please post your setup so that Akis can insert it into the "working setups" thread.

I believe you have been given some bad information. Sonar kicks with 4 and even more processors. I can confirm 4 as I just built a Quad and it purrs along where it used to struggle on my X2-4400. Samplitude does seem to run better if you are using ASIO. quite smooth! And, I have had zero trouble with UADs too. I got the quad because it and my X2 were not getting along and it was locking the computer up constantly. So far, not a single one with the Intel Quad (Q6600)

Just wanted to set the record straight.

I don't agree with you.
Besides, I'm speaking of taking "full" advantage of the QUAD, by spreading the load evenly, not issues. Reaper is the only program I have come accross that ccomes close. Not SAM not C4...Sonar's a muncher.
You can see this by simply opening the task manager, upon playback.
It's that simple.

I'm having a problem stacking UAD plug-ins in Sonar PE 6. In Sonar 5, I could stack multiple plug-ins.... (Pultec Pro, LA-2A, Plate 140 for example). In SPE 6, I can't get beyond stacking two plug-ins, even if I add the third plug-in into a bus and insert a send on the channel with two UAD plug-ins. I can add the third plug, but when I hit play, the audio engine stops immediately. I have tried the \"disable cur, hit play, enable all\" trick, but it won't work.

I've tried adding UAD plug-ins to other tracks that don't already have UAD plug-ins on them, and that works fine until, of course, the UAD limit has been reached. I've also tried playing with adding buffers to my Q10.

Has anyone experienced this and if so, how can I work around this without having to freeze or bounce tracks?

I am adding this post to this thread because someone on the Cakewalk/Sonar forum suggested that I turn the Multiprocessor option off to eliminate the problem.

My configuration:
P5B-E, e6600, corsair xms2, Aardvark Q10, Sonar PE 6.2, 2 UAD-1 cards on 4.7, EVGA 256-P2-N429-LR GeForce 7200GS


Your help or advice would be greatly appreciated!
