One additional observation set: while the CPU consumption, GPU consumption, and result files do not change, and one might imagine nothing going on, Process Explorer shows considerable I/O and context switches by the test Windows application:

at the 53 minutes elapsed point:

1. 8,086,142,000 I/O Read bytes
2. 5,120,204,520 I/O Write bytes
3. 4,694,559 context switches

The rate of I/O read, I/O write, and context switching seems pretty stable.

Did you check where this I/O goes? What file read/written ?

I tried to download filemon, but Microsoft no longer hosts that and advises using Process Monitor instead.

In Process Monitor, I tried launching it after your test application was already running, and used the filter function to see file operations only for the PID of your application.

The file activity shown for this application is to a continuing series of files in the location c:\Users\myuserID\AppData\Local\Temp

Files are created, read, written and closed, with names like:

OCL5CB0.tmp.cl
OCL5CB0.tmp.log


While the great majority of the file operations I see in my sample are to files in this single directory, I did see a single ReadFile simply to C:

I also saw a short burst of operations (CreateFile,QueryBasicInformationFile,CloseFile) to these two files:

c:\Program Files (x86)\ATI Stream\lib\gpu\builtins-7xx.bc
and in the same directory builtins-gpucommon.bc

Process monitor allowed me to save the file activity log for this filtered to your application file information in CSV form. I'd send it to you if you like, but it is 58 Megabytes itself, so even if you find it interesting, perhaps I'd better pull out a much shorter sample before sending it.

Here is an extremely short sample, just to show the format and flavor:

Ok, I see.
Looks like OpenCL runtime can't create needed kernels...

I have some other Problem with my low end HD 4670. Because of missing PCIe, I used the AGP-Version of this Card. For this, you'll need the Special AGP-Hotfix Drivers to run. The Card works fine with Catalyst 10.12 an SDK 2.3. But (and here's the problem), the AGP Driver does not support OpenCL, so I try to run the Astropulse Lunatics release for older Cards (ATI CPU/GPU Hybrid No Double r453). The Application runs in Boinc, but the GPU ist not used. Only CPU is crunching. Any ideas?

Regards Odi

The GPU is used with the Hybrid app, but only in small blips, since it is mostly a CPU app,
run times will be mostly dependant on CPU used, my XP3200 only got half a day speedup,

There is an AGP Hot Fix version of the 11.3 APP driver, I believe.

It's good to be back amongst friends and colleagues

Yes, there is, but the 10.12 is the last driver with works with this card on my winxp system. After 10.12, the HDMI-Audio Driver is included in catalyst and this breaks the installation with a nice bluescreen ^^

Ok. Thx for the info.

could you download the separate parts of the drivers to exclude the HDMI. Also when installing can you choose custom install and unclick the HDMI

Still tuning the rev516 AP app., unroll=20 killed some AP WU's, sorry wingmate.

GPU's now doing a few MW, probably slipped in, rig is now using 650Watt and
have to turn GPU & memory clock down.

Have a new and promising cmd line parameters, atleast on HD5870('s).

4000 series ATI RVxxx, has different achitecture, 5000(REDWOOD,CYPRESS,?) series revised architecture and more and better use of the Compute Cores,
6000 series (Cayman) have yet another build.

GPU load is now reasonably constant 55% till 85% (Unroll 15) and ffa_blocks of 6144 and Blck_fetch 3072, but you've just have to change these parameters, keep ^2, in mind and data_chunk_unroll>16 doesn't work, or freezes the system, at 20, it's over!

Ehh, b.t.w. I probably made a partly double-post , s o r r y . . . . .
Keep on Crunching...

Editted: [i]ffa_block value 6144 not 6244, my bad, but do change.
