Any idea why the new units keep failing?

Using a R9 Fury card, latest drivers.

try taking every thing out of the .config file and then restart boinc

Assuming Windows, the Collatz home page points out the new version of Collatz Sieve requires installation of the latest C++ runtime (and provides a link). But it neglects to point out that after that install, Windows must be rebooted. Those two steps ended my "computation error" failures.

Ok I have updated to the latest version of the runtime, rebooted and removed my collatz_sieve_1.21_windows_x86_64__opencl_amd_gpu.config and collatz_sieve_1.21_windows_intelx86__opencl_amd_gpu.config files but still no go, any thoughts?

Message 21429 - Posted: 6 Oct 2015, 0:14:28 UTC

Ok got the units working, if I put in my old config file it causes it to fail again.

So is there any optimizations I can do for these units? the file I was using for large units got my times down from 16 hours per unit to 4 hours, so wondering if I can do similar with these or are they already very optimized?

This is what I was using before :

verbose=1
items_per_kernel=22
kernels_per_reduction=12
threads=12
lut_size=16
sleep=1

Your run time for each unit is @140 seconds now.

I believe for collatz_sieve_1.21 we no longer have items_per_kernel, instead we have sieve_size

Ok so what should I be running instead?

This?

verbose=1
sieve_size=22
kernels_per_reduction=12
threads=12
lut_size=16
sleep=1

Bump, can someone confirm the config? also what are you guys using?
Are configs like this just used for collatz or could I use something similar for other projects to increase output?

Some other projects have config files for some apps but the settings are specific to the project and app.

Those should be pretty safe settings for the current sieve app.

threads=12 seems a little high but the app _should_ reduce it if it is. You may actually get faster results with a lower number (e.g. 7 or 8) though.

kernels_per_reduction=12 could be low but will give good video response. If the machine is a dedicated cruncher, you can probably increase it to 32 or even 48.

sieve_size=22 is very safe. Chances are you can use 25 or 26. If those work OK, try 27 or 28. Higher numbers will use more GPU and system RAM. Too high and the driver will crash and the WU will literally never finish. Too low and the GPU won't run at top speed. Use GPU-Z or a similar tool
to monitor the GPU load and temps. My laptop actually runs faster with smaller settings because the higher ones cause it to overheat and the driver then throttles back the speed. By using slightly lower settings, that doesn't happen. Each GPU is different so the settings for one model may not be the best settings for another. They should be pretty close though if in the same same family.

you could try this:

verbose=1
kernels_per_reduction=48
threads=7
lut_size=16
sleep=1
reduce_cpu=0
sieve_size=30

I did try some settings for my setup and the speedup was considerable but there was a jump in heat and running stock was already hot enough for my liking so I'm staying with stock for now.

The last 7 of the GPU sieve workunits on one of my computers crashed with computation errors - one after running about 60 times as long as the initial estimated runtime, and the rest within the first 10 seconds. Could you check if there's something wrong with an input files shared by at least the last 6?

All ran with the stock setup.

The last 7 GPU sieve workunits on one of my computers all gave the same unknown error number.

Exit status -1073741515 (0xffffffffc0000135) Unknown error number

Nothing in the log file saying why the error occurred.

For thoughts who are getting error on their WU's do what I've done and remove project and reinstall It. This seams to correct the error which seams to be in the project file.
