'Reverse HT' for Dual cores?

[neonblingbling]

I was curious if there was some something out there that would be the 'reverse' of the Intel HyperThreading. Basically, I would like something that would allow both of my 2.0GHZ cores to run as one 4.0GHZ core in Windows XP.

Yea, it is against the mainstream 'multi task = teh win', but using Winrar to compress 20GB of raw video isn't fun...

On that note, is there some software out that is a multithreaded Winrar?

as of v.3.60, Winrar is supposed to be multithreaded:

Version 3.60
Multithreaded version of RAR compression algorithm improves
the compression speed on computers with several CPU,
dual core CPU and processors with hyperthreading technology.
Multithreading is enabled by default, but you can disable it
in "General" part of "Settings" dialog.

In the command line mode you can control multithreading with
-mt switch.

There is an option like this hidden on some intel boards, but the option was left out by intel in the bios for some unknown reason. It is called core multiplexing.

We will just have to wait upon word of a release in the bios before we can begin taking advantage of this call little gizmo.

Rawr. Curses for not keeping up to date software.

Interesting. Core multiplexing, Matrix Raid, C2D... Why are all the cool stuffs with Intel?

Thanks.

What? I've heard of the Reverse HT but first time hearin this Core Multiplexing. Definatly come in handy.

"Reverse HT" doesn't really exist like this. It's not possible to combine the execution units of two seperate cores (joined at the L2 in the case of Conroe or at the SRQ in the case of the K8). The only way to do "reverse HT" would be to have the cores completely combined - in which case you just have a (significantly execution-unit heavy) single core that can run two threads. So just normal hyperthreading.

I'm personally a big fan of this approach (the "load up the core with lots of threads and keep the execution units at 100%" approach, essentially hyperthreading but more so), though this is probably because most of the computationally intense stuff I do scales well for multiple cores/threads. Take a Conroe, double the number of SSE execution units, allow 4 or 8 threads per core, and that's a CPU I'd buy in a flash even at twice the cost of a regular Conroe.

Core multiplexing (aka speculative threading) is something quite different, but also very interesting.

listen to emboss, reverse HT is a myth.

 

[deathman20]

Well its a myth but its a nice one

Just like that uber PCI graphics card hehe, or was it agp forgot, either way its a monster.

 

[hUMANbEATbOX]

don't think i know what you are referring to. are you talking about the dual/quad/octo gpu 9700's that were apparently made but never sold by ATI?

Or that awesome network card that could reduce your ping on the internet and make your 14.4 modem act like DSL ... uhh, hang on ...

Na its called something like the 5500. Im sure there is a more then a few threads on this in the video card section.

Oh a new one haven't seen that one yet.

here you go, a $250 nic.
