Priority in XP.

It took me a while to figure out...
Here's the commandlines to start Logic in "AboveNormal" or "High" priority in XP:

D:WINDOWSsystem32cmd.exe /C "Start /AboveNormal /B /DD:progra~1emagiclogic5~1 D:progra~1emagiclogic5~1logicp~1.exe"

D:WINDOWSsystem32cmd.exe /C "Start /High /B /DD:progra~1emagiclogic5~1 D:progra~1emagiclogic5~1logicp~1.exe"

(Feel free to modify for your own use

)

I prefer "AboveNormal" for Logic and "Normal" for SFP, but in some "cpu-heavy" situations it might be better to run Logic in "High" and SFP in "AboveNormal".
Any of you guys & gals have experiences ?

Kim.

This is something I was unfamiliar with enough when I first wrote the 2000/XP guide that I left it out. It is very important, so thanks for posting this, I hope to get more comfortable with this and add it to the 2000/XP guide shortly. Thanks kimgr, always a great source of information, and definitely smarter than myself!

Coming from you, that's a compliment, even with the :vink:

Additional tip:
To see short versions of filenames, use "dir /x" in the command prompt.

wow I understand nothing of what you guys just said

And that's sort of why I was waiting for something more like this:

<a href=http://www.gameroffice.com/>WinLauncherXP</a> - utility to set CPU Affinity (for dual processors), and Application Priority. FREE.

<a href=http://www.orionsoftlab.com/tm/tm.htm>Active Task Manager</a> - Also has CPU affinity settings, can automate starting executables, and costs $15.

I haven't tried either of these yet, but will shortly. The first one seems the the most promising as it's free, and you can set affinity and priority for your programs...

Is this just a Logic thing? Will this give the sequencer more resources than the usual maximum or just a greater share when the CPU is heavily loaded?

I think that Steinbug's programs handles priority them selves, or you can tweak it in audio-system-settings-advanced-something...

Yes, Steinberg's products and Cakewalk's are both properly SMP aware, which means that they're properly threaded to coexist with other threads and their priority level.

Windows NT/2k/xp threading is actually really simple compared to *nix. Afaik, in *nix you have 127(8?) levels of priority that can be assigned to different tasks or groups of tasks. If I remember correctly, with NT you have 4 levels (0,1,2 and 3) which are Realtime, High, Normal, and Low. Win2000 and Xp add Abovenormal and Belownormal settings as well.

It's not necessarily simple at first for programmers who are used to multitasking, but separate threads normally are programmed to be aware if threads they are reliant on are available/finished etc. so being aware of timings is more critical. It's my understanding though, that once you've learned to thread your code it's really easy to see the benefits.

Btw, I thought I'd mention that a friend and I tested his logic on my dual system with the Pulsar and it's actually a lot more stable than Nuendo, even when multiprocessing support is turned off in Nuendo. I can tell the difference in the amount of processing i can do in software though, and the pulsar's still buggy especially with reverbs and delays.
