When selecting a new machine, what type of cpu-architecture really makes sense when running win xp + vvvv?
Are multicore processors being supported at all?
And what about compatibility with 64-Bit Systems?
Personnaly we use quad core which is really flexible and powerful.
In vvvv it is usefull for HD video streaming for ex.
The possibility of managing the 4 differents core is usefull too, to attribute diffrents instances of vvvv.
So I would recommend a Core™ 2 Quad Q9550 or better the new i7 Core™ i7 920.
We often use machine with old quad Core™ 2 Quad Q6600 which are really nice .
About 64 bits , no infos !
And what about compatibility with 64-Bit Systems?
We often use 64bit XP, no problems so far.
If you apply a patch to the vvvv.exe you can use up to 4GB of Ram on 64-Bit systems. Just get yourself a copy of Microsofts imagecfg.exe, place it into the vvvv directory, open up the commandline and run the following: “Imagecfg -l vvvv.exe”
Ok, thanks.
But Björn, does 64-Bit XP have any positive impact on vvvv’s performance at all?
I mean, does just run or does it run better/faster?
it just runs. Except for the additional memory I don´t know of any advantages.
added valuable info to System Recommendations
Video is decompressed across multiple cores as are freeframes, s theres another reason…
hmmmm
i wonder if it’s still usefull to patch vvvv.exe on win7 x64?
i try that cmd:
Imagecfg -l vvvv.exe
but return an invalid switch (-l is not in the list)
the -a 0x1 switch works but hmmm
no need to assign vvvv.exe to a specific processor permenantly
since it’s done by design?
There are at least two different versions of imagecfg one that supports the l-switch and one that doesn´t. I googled a little but couldn´t find a valid download source for the exe that supports -l.
But there seems to be another way. (The first step isn´t necessary)
I haven’t tried this yet but catweasel posted about running 2 vvvv instances in separate cores to offload the interface onto its own core… http://vvvv.org/users/catweasel
thanks bjoern & gilbi
added the alternative method to the System Recommendations
64bit wont make a difference, as the application needs to be compiled with a different instruction set (x86-64).
Since every value in VVVV is a 64bit value, there’s a chance there might be some speed increase.
But the real slowdowns aren’t in the arithmetic, so i wouldn’t expect it to make a useful difference.
thanks for your light elliot
i even don’t know how to make a performance/benchmark test in vvvv
to evaluate the difference…
