DMC Reference without dual core processor?

[drspy00]

With DMC Refence, is it possible to turn the dual core encoding off?
I have a computer thats a few years old so doesn't have a dual core processor. When ive tried to convert from wav to flac it converts using 2 processors which i dont have, and it seems to go very slow and the conversion fails anyway so it would be great to be able to set it to just use single core cpu as thats all I have.

I would appreciate any help.

Does your processor support HyperThreading? If so, then your CPU shows up as two processors.

I think it does, its always shown up as 2 processors in the device manager in windows. Is there a way to disable dual core encoding?

Does it usually just display encoding as a single core processor if the processor doesn't support hyper threading?

[LtData]

If the processor is a single-core, non-Hyperthreaded processor, then yes, it only encodes one file at a time.

If the processor is a single-core, non-Hyperthreaded processor, then yes, it only encodes one file at a time.

Just a guess, but I think if you set the processor affinity (via file/preferences, or perhaps task manager is more likely...) of the starting application to one of the two, it will only use one of the two virtual processors. Not sure if that will prevent any executables launched from the ripper from using another processor, but it should stop threads from doing so.

I tried this and it didn't work. It still encodes two files at once, but now it just does 100% on one CPU and probably goes slower than one-at-a-time encoding.

[drspy00]

Yeah its actually slower than it has ever been in this version. I only really wanted to use the reference version because I want to be able to keep the folder structure of files that are encoded.

Encoding 2 items at once, even on a non-multi core system (ie hyperthreading) would not slow the encoding down, if you convert 100 files on a single core machine it takes the same time as 100 using 2 pretend cores.

I believe the original poster indicated that the process fails for him in it's current state. I don't think he is interested in how fast it fails.

I also would like to see the ability to limit the number of cpus (I have two real ones.) Running two at a time slows all other applications down. I tried setting lower priorities but wasn't convinced this is as effective as limiting dMC to one processor.

It does work sometimes, it just has more likelihood of failing, and makes everything else slow, i used to be able to leave it run in the background and could do loads of other things aswell but too slow for that now.

You have set the priority to 'idle' (on converting page)?, then dmc should not effect any programs.
