Support of dual core CPUs.... (1 Viewer)

[ReyF]

Hi,

can somebody tell me if MediaPortal supports dual core CPUs? Especially Core Duo T2400?

Thanks,

if you ask if it uses multiple threads, no it doesn't (AFAIK)

but works fine on a DC CPU

I was asking if it is capable to use both cores. It is clear that it is working with dual core CPU.
That is pitty! I think that when e.g. you will record some movie from TV card and will be doing something else it will be worth it to be MediaPortal capable of using both cores.

Of course multi threading has many advantages, but damn it's more complicated to develop and doing very bad things is very easy ! I think we could make some dual core operation for E.G. Compress to Xvid but I think this is already available if you're using an external app.

I know it is not easy. I was just asking because the HW requirements according what is written on MP webpage are pretty big. Now I am bit unsure if I should buy Core Duo or Core Solo. May be the best will be to buy Core2?! ;-)

It is clear that when I use external app. for video encoding both cores will be used.

Stick with the Core Duo platform only because other software packages will allow for multi-threading. Most people have several other pieces of software on their HTPC's - MP just isnt at the point yet where it can be the only program running on a machine to acheve everyones goals.

I think that when e.g. you will record some movie from TV card and will be doing something else it will be worth it to be MediaPortal capable of using both cores.

Considering that recording with an analog hardware capture card utilizes about 5% cpu usage, and that alone is from driver overhead and I/O utilization, I would say that requring multi-threading for capturing TV is not required at all. You can capture TV with an analog hardware capture card on a Pentium III if you really wanted to. :lol:

I can understand your point about xvid encodng TV shows, but in reality, the trick here isn't more power - it's stratgic use of time. have the HPTC re-encode content at night when you're asleep or when the system is not in use. I have my HTPC schduled to wake up every monday at midnight and perform disk utilities (scandisk, defrag, disk cleanup) and then MP will encode all my recorded shows to xvid and delete the originals. When done, the system will turn itself off.

Personally I would recommend just buying a cheap single core processor if the computer is mostly dedicated to MediaPortal, as most of the work is done by the video card as long as you have a compatible one. CPU utilisation should not be high anyway, and a slower, single core processor will probably put off less heat as well, which is always a good thing.

I have a DC cpu and quite often use it as 2 seperate CPU's. Using the afinity setting in task manager I assign MP and internet to core 0 and have Ulead DVD Movie Factory 5.0 assigned to core 1.

MP and internet are quite hapy using core 0 and the max load on this core is about 30%.

Ulead is crunching numbers on core 1 with a cpu load af 98%

In the past when I did this on a single core cpu with hyper threading it always lead to problems with the data recorded with MP or crashing of MP.

Now with the dual core cpu it works perfect. Still trying to do more at the same time, have not reached the boundry of capabilities yet.

Probably with the announce TVEngine 3.0, the UI will be decoupled from the recording engine. This will imply that they will have there own thread (and thus use the separate core).

Hopefully if you have multiple tuners, when they record they also have there own thread (or process), then you can even have advantage of a quad core 8) .Although they each core will be under-used.

Does the single thread nature of MP mean that even "external" stuff such as codec dlls, movieplayers, etc can not be mt/dual core?
