Update:

It was the new GPU drivers that made a mess of things, the "Crimson ReLive Edition 17.5.2 Optional" update.
Reinstalling the "Crimson ReLive Edition 17.4.4" made everything work again, and I had to remove the modded cc_config.xml again to allow BOINC to use the RX 480.

Tom:

Not Windows update but close! :)
The XP box is an old computer that has been reborn as a cruncher after I transplanted 14 new caps on the motherboard - the old caps were bulging and leaking.
It's running Windows XP 64Bit with SP2 - the latest made.
I might try an upgrade to a more recent Windows but AGP and multiCPU's don't mix so it will not join the GPU crunchers.
For those interested: Iwill DK8N motherboard with 2 Opteron 265 CPU's and 4 GB RAM. Empty AGP slot, but I don't know if any of the old AGP Gfx cards will crunch for Seti.

The reason I tried to get rid of 1 virtual GPU was that it reported an estimated time of completion around 147 days when I last saw it...

Temporary fix discovered:

Made a cc_config.xml file and added this:
-----------
<cc_config>
<log_flags>
</log_flags>
<options>
<ignore_ati_dev>0</ignore_ati_dev>
</options>
</cc_config>
-------------

Now I get this message at startup, and 1 GPU task running:

26.05.2017 13.55.53 | | OpenCL: AMD/ATI GPU 0 (ignored by config): Radeon (TM) RX 480 Graphics (driver version 2348.3, device version OpenCL 2.0 AMD-APP (2348.3), 8192MB, 8192MB available, 5834 GFLOPS peak)

Thanks for the reply!
No, I have not moved the RX 480 around - it has always been seated in the uppermost slot and I just checked - it is still there! :)

Trying to remember anything unusual the last days, I had to restart my computer after updating to the latest drivers for the RX 480, Radeon 17.5.2, but it seemed like a normal restart.
All other programs shows just 1 RX 480 in my system.

When I checked how the crunching was progressing I noticed this in the eventlog:

Just to clarify - I got only one RX 480.

How can I get BOINC / Seti to do a new detection of hardware to get rid of GPU 1?
Any ideas are welcome!

Hi!

I'm waiting for the new server to show up as everybody else, as my computers are beginning to run out of work - but I'll live through this.

Would it be possible to make a backup of the database distributable as well as the WU's?
I wouldn't mind setting aside a few gigabytes to store a part of the database, if it could help the project.

More info:

SeeSawPro seems to loose the settings everytime a WU are finished and a new WU are started, so it's not very useful in the long run.

I'm now testing Trux's calibrating BOINC with Crunch3r's client and the <cpu_affinity/> command.
So far I have succeded to isolate the process on CPU 1 - both cores.

Now I will have to wait to se if it's working.

I have the same problem with my new Opteron's.

Time before upgrading the machine, with 2 x Opteron 242's at 1,6GHz each: 53 minutes on each CPU.

After: about 140 minutes on each of the 4 cores on my new 265's at 1,8GHz.

I'm currently running SeeSawPro, and at least each core uses about the same time and are not fluctating wildly.

The computer: http://setiathome.berkeley.edu/show_host_detail.php?hostid=2316167

Running benchmark using crunch3r's 2,09 version:
2x242's ( two cores ) = around 5700
2x265's ( four cores ) = around 3500 ...

Any tips on how to fix this are welcome!


Edit: Editing the prefs and reducing the available CPU's to 2 made the benchmark look better - 7447. But I really would like to be able run all 4!

Edit2: Weird things seems to be happening - check out this result:

( std_err.txt seems to be repeating itself 6 times?! )

Hi,

the new client is ready for download (got the licenses today).

You can get it here.




oh no, here we go


Yes - here we go! :D
I just hope I can use the Athlon64 SSE2 client on my Opteron rig?!
