Multicore processors

[rock]

Does anybody know whether RiffWorks Standard supports multicore processors? Thanks

[Charvelguy]

yes, but runs on one side or core.

yes, but runs on one side or core.

you cant be too sure of that, because the OS will assign a thread to the most availible Core, possibly bouncing it between cores.

Will it run with a dual core? Sure....any # of cores is fine.......is it optimized for more than one.....maybe sorta no

[cwight]

I have a dual core processor....it runs....

I have an AMD Quad Core whatever the bleep that means

[ShredRex]

Bill it means you have 3 more than you need.......lol

[Rotund]

I have 2 Cordis Cypher Sirolimus-Eluting and 2 Taxus Express Monorail Paclitaxel-Eluting Systems for a total of 4

No wonder you can't sit still for long !!!

i have a quad core. runs very well.

[vad1er]

I have two dual core Xeons runs great with them.

I've got a Intel Core2 Quad. The question here needs to be rephrased. Is RW designed (on a sourcecode-level) to leverage multicore systems (Quad/Dual or even up to 8 cores (two Quad Core CPU's))? That is, does RW do parallell processing?

First: XP/Vista will automatically balance and distribute the processes/threads within your system to different cores, you won't even notice it (it's called transparency).

Now, you do have an option to affect how your operating system (OS) assigns processes to these cores, lets say that you have a quad core, this means you have 4 "CPU's" to play around with, and that you are batch running some software in the background (like a backup program or burning DVD's, whatever) while playing around with RW simultaenously. Using theTask Manager you can now assign these processes to separate cores using the affinity manager. Generally you don't need to mess around with this option since the OS does a pretty damn good job for you. Usually people who runs multiple OS simultaenously (like native XP and a virtual Linux) assign the virtualization to a designated core using automatic affinity.

Some COTS software like Adobe Photoshop are designed to leverage multiple cores. This means that there has been an intentional engineering effort made to do things in parallel within the software which is quite advanced. When I run RW on my quad core system I would be able to see multiple RW threads in the Task Manager if this would be the case, which I do not.

So if you are running RW on a multicore system you are not really benefiting from it besides having the possibility to effectively run other programs simultaenously.

I assume the above text qualifices as bollocks?

You can use "SMP Seesaw Dual Core Management" free application to manage the cores not only for RW. but any other application....

good to know since i just ordered new computer with the new intel i7 monster processor. i think this one has 8 cores. its gonna run vista home premium 64 bit,i hope this won't create any problems for rw and other apps.
