As a matter of fact, yes.
Andrei, at least show me the results on your i5 - on a clean CPU. I'll be happy for you.
No, not on these, but on the one I attached in the last post. Exactly on it exactly. Posting my result on this script:
2012.04.21 19:32:43 ParallelTester_00-01x (EURUSD,H1) CpuTime/GpuTime = 83.99644128113879
2012.04.21 19:32:43 ParallelTester_00-01x (EURUSD,H1) Result on Cpu МахResult==1.26619 at 856 pass
2012.04.21 19:32:43 ParallelTester_00-01x (EURUSD,H1) Соunt indicators = 16; Count history bars = 144000; Count pass = 1280
2012.04.21 19:32:43 ParallelTester_00-01x (EURUSD,H1) CPU time = 23603 ms

2012.04.21 19:32:19 ParallelTester_00-01x (EURUSD,H1) OpenCL init OK!
2012.04.21 19:32:19 ParallelTester_00-01x (EURUSD,H1) CLGetInfoInteger() returned 1
Processor:
2012.04.21 17:51:14 OpenCL CPU: Intel(R) Corporation Intel(R) Pentium(R) CPU G840 @ 2.80GHz with OpenCL 1.1 (2 units, 2800 MHz, 8040 Mb, version 1.1)
It is strange, your file name seems to be
paralleltester_00-01x.mq5, but saved as ParallelTester_00-01x__1.mq5
Strange, you have the file name as
paralleltester_00-01x.mq5 but saved as ParallelTester_00-01x__1.mq5
It is nothing strange. It is just that the file with such a name already exists and that is why it adds __1. Where is the test for ParallelTester_00-01x__1.mq5, Andrew?
I see it is very good. A bit worse than I expected (I hoped for 140-150), but still very good. In principle a variation of this ratio within 20-30% is normal (especially if the GPU time is low). By the way, if you, say, do the following:
#define CountPass 1280 * 10
then you can count on another record for CpuTime/GpuTime ratio. Your "theoretical limit" is something around 170-180. For me, at least, it was almost 90, and yours should be twice as much.
Mathemat:
#define CountPass 1280 * 10
then you can count on another record for CpuTime/GpuTime ratio. Your "theoretical limit" is something like 170-180. For me, at least, it was almost 90, and for you it should be twice as much.
This is at 1280*10:
And at 1280*128 I just got tired of waiting and forcibly shut down the script:
Well, finally, we have been waiting for you. If you are ready to experiment, install Intel OpenCL Runtime ( see link for instructions).
Run the script without changing anything in it and post the log from "Experts" tab just like your previous colleagues did. The script will take about 3 minutes to run on your gem, bear with me. At the same time we will see how OpenCL runs on the coolest barebones Sandy Bridge stone.
If you don't have the patience or if you think it's beyond your abilities, that's OK, no offence taken.
P.S. The purpose of this script is to see what a bare CPU can do without any discrete video dragons. I suspect that with Intel Runtime properly inserted, this script will have acceleration around 200 or even slightly higher.
