Chrissy, How about AMD Dual Core CPU Compatibily.

[ViRuS2k]

When useing SVCD2DVD the program is only useing %50 of both my cores
or when i set affinity to 1 core that 1 core uses 100% but the other core is 0% usage.

if you want me to test beta for you let me know...

btw makeing the program multithreaded wouldnt be a bad idea either.
there are lots of people now with dual amd cpu`s....

and also thankyou if it wasnt for you i would be stuck
this simple program is a very helpfull program
thankyou again.

[ViRuS2k]

nice, not even one single reply lol....
i guess implamenting dualcore,multithreading is to hard.

[ChrissyBoy]

Well i have looked at this previously, but was only able to test on a P4 HT box. Is dual core essentially the same as HT?

[TBoneit]

AS I understand it on WinXp a dual core will show as two CPUs, same a 1 CPU with HT does.

OTOH if they are running the extreme version of the dual core P4, That would be 2 Cores with HT it should show as 4 CPUs and may or may not need a 4 cpu version of XP. I haven't tested as the extreme is way to pricey for my wallet. Logic says that two cores with or without should be fine on the standard Xp, OTOH since Xp handles a HT P4 as if it were 2 cpus who knows. If anyb ody has this pricey bit of hardware and installed XP and can see it as 4 cpus on the 2 cpu version, chip in.

Thanks

i think its basicly the same yes.

i can beta test if you want as i have the cpu to test..

AMD64 X2 Toledo 4400+ Dual Core.
when installing winxp os the cpu is just like any AMD cpu with only 1 core activated thats Core 0
when you install the AMD drivers and reboot winxp then see`s both cores

Core 0 aswell as Core 1

SVCD2DVD see`s both cores but only balances them at 50% speed on each core.
if i set affinity to 1 core then svcd2dvd will use 100% of say core 0 but core 1 will me idleing

if you wish i can test beta for you let me know as im willing to go though anything you ask to get this feature implamented
it would theoreticly cut the encode times in half lol

regards.

[ChrissyBoy]

ok. My initial tests saw an improvment of around 10% only.... When i get some more time i will send you some builds to test. Thanks.

thanks mate my email is : auih77@dsl.pipex.com

ok. Can you post what is says in the logs files for your processor?:

e.g:

there is 2 instances in there, whats also weird is my cpu`s L2 cache`s
there listed as 2x1.00kb when it should be 2x1024kb hehe
and also speed is off im currently running at 2.7ghz with a 170fsb

anything else you want to know let me know asap m8

[ChrissyBoy]

CPU FSB is small too... i assume that is bollocks?

[ViRuS2k]

yeah the speed and fsb might be off becuse havent used it in about 2 days and + i was overclocking and testing stuff so ignore those readings for the time being

but the L2 cache`s wouldnt have changed no matter what hehe
so those probably need looking in to as for anything else you need to get started ect let me know ill be here all night to help as much as i can

[ChrissyBoy]

Well what i suggest (as I'll be downing tools soon for the night) is that you do a benchmark run with the current build. (bog standard AVI->DVD or HDTV->DVD) and take note of the timings... I will send you a build to test shortly to compare against.

ok mate i will record the time of say a svcd file and xvid file
and also record the cpu usage aswell with a stopwatch with pictures to follow.

then i will post those up and do the exact same on the build you send
so we can compaire....

then we can do more tests to get the full dual/multithreading enabled

[ChrissyBoy]

ok. the svcd test will not show much (if any improvement), as it is pure IO... Check your inbox for the test build...

[ChrissyBoy]

Let us know how you get on....

[ViRuS2k]

Let us know how you get on....

here is test i just did with the original build i will do the same test with the new build and post pic later.

this is a EPS of LOST in .AVI xvid format.



as before only 50% of both cores where used no suprize there
hehe ok testing the new build now to see if the timeing and cpu usage has changed.

[ViRuS2k]

update mate
this is a pic from the updated version

there is improvments

cpu usage goes up to 60%-75% on both cores
just need to up that to 100% on both.

next svcd2dvd when installed and started up is useing a LOW cpu priority
if you check taskmanager under svcd2dvd.exe and check its priority it seems lower than a normal app....

also the module AVI2MPG used when converting XVID or ACI Xvid is higher on cpu usage 60%-75% needs to be 100% though on both cores to be fully effective

the other modules within svcd2dvd dont seem to use as much cpu usage as the AVI2MPG module so those need upped aswell

but things are looking great time have indeed improved as you can see from the pics from the start times to the ending times.

just need to do some fine tuneing.
let me know when you got another build for me to test mate....

im likeing what im seeing so far very much and AMD64 duel core users will love it aswell

[ViRuS2k]

chrissy any news m8 im waiting lol

[harrisonford]

Chrissy,

I might help if your looking for true dual core intel machine, I have a dual pentium 4 xeon and HT,if need help, sorry not much of a programmer, but might help a little in some way if you need testing, oh 2 gigs of ddr 400 Ram, I can use any tools to test cpu or mem test, this is rather simple.

[ChrissyBoy]

harrisonford: Will do. I will send you a build to test when my ADSL sorts itself out.

virus2k: Thanks for the testing... interesting results. My take is as follows:

            OLD         NEW
AVI2MPG     26:39       17:51
Total       37:30       28:36

The AVI2MPG process is quicker by 49% and the total processing is 31% quicker.

It is as expected. The avi2mpg process is the only one which will use both processors effectively: the other processes are more IO intensive.

But nearly a 50% speed increase in encoding is certainly going to be welcome.

np mate im glad to help.
is there anything else i can test

how about upping the AVI2MPG even further so that it uses 100%/100% on both cpu`s, your nearly there.
and any other modules you can get working with faster processor use is welcome aswell.

you should also add in the programs settings a dual cpu box that you need to tick if your useing dual core cpu`s that way its easy for people with amd`s to use that method and that way it doesnt interfear with normal cpu users.

also avi2mpg is used for .AVI and XVID right
how about upping the module thats used for SVCD and VCD ect....

im here to test all night matey..
