You have 0 - video card?! Amazing.
Actually, 1, 0 is a proc. But I learned about it only through scientific experimentation.
mql5:
The OpenCL functionality of the language is going to be extended (supplemented) soon. So it will be possible to find out who is who.
Thanks.
Try using this structure, it didn't work for me (I suspect the second dimension has to be a fixed size, that's why it didn't work for me):
And, for convenience, a function like this to resize both dimensions:
It didn't work for me either... I'll have to think about it.
Please Help!!! Can't figure out what I'm doing wrong!
In short, I can't set a structure with quotes as an OpenCL buffer... I can't understand what's wrong with it, but it's transferred, but the values are messy.
Please Help!!! I don't know what I'm doing wrong!
In short, I can't set a structure with quotes as an OpenCL buffer... It's passing, but the values are messy, I can't understand what's wrong.
Try it this way:
Thank you! Everything works! Forgot about the alignment in the structure...
On the subject of OpenCL, an "acceleration" came up ))

............. We should get MetaDriver there - then maybe we can take the inverted commas off, too.
What's the purpose? To test it on my card?
News from the field:
Support Team has confirmed my nubian suspicions that CLContextCreate( 0 ) is not performing calculations on IGP, but on x86 cores. Here are the results on an i7-920 CPU which has stupidly no IGP:
On intel's OpenCL it runs faster ~160ms
Here are the logs from AMD
2012.04.18 11:20:28 ParallelTester_00-01x (EURUSD,H1) Result on Cpu МахResult==0.62834 at 742 pass
2012.04.18 11:20:28 ParallelTester_00-01x (EURUSD,H1) Соunt indicators = 16; Count history bars = 144000; Count pass = 1280
2012.04.18 11:20:28 ParallelTester_00-01x (EURUSD,H1) CPU time = 31528 ms
2012.04.18 11:19:56 ParallelTester_00-01x (EURUSD,H1) Result on Gpu МахResult==0.62834 at 742 pass
2012.04.18 11:19:56 ParallelTester_00-01x (EURUSD,H1) Соunt indicators = 16; Count history bars = 144000; Count pass = 1280
2012.04.18 11:19:56 ParallelTester_00-01x (EURUSD,H1) GPU time = 483 ms
2012.04.18 11:19:56 ParallelTester_00-01x (EURUSD,H1) OpenCL init OK!
So on Intel OpenCL Runtime on the same stone will be CpuTime/GpuTime ~200. And why would I need a discrete card - with that kind of acceleration!
Graff: I don't have integrated card (neither in my CPU nor in my motherboard).
And it should work on your i5-750 too, try it! Intel says that OpenCL is supported not only on Sandy Bridge but also on previous generation and even on latest Core 2 stones.
P.S. Unfortunately, it looks like it's not all that simple: Sandy Bridge has turned out to be a tough nut to crack. So far, only one stone - Pentium G840 (mine) - has guaranteed real acceleration.
