This thread is specifically for Collatz Conjecture project support.
Collatz Conjecture Website

Project info:
Collatz Conjecture is based in Wood Dale, Illinois, USA and continues the work of the previous 3x+1@home BOINC project which ended in 2008. It can run on an nVidia GPU, ATI GPU, Intel GPU, or Intel or AMD CPU.
Collatz Conjecture is a research project that uses Internet-connected computers to do research in mathematics, specifically testing the Collatz Conjecture also known as 3x+1 or HOTPO (half or triple plus one). You can participate by downloading and running a free program on your computer.

Information for new accounts at Collatz: Due to some relentless spammers, Collatz Conjecture now requires an invitation code to register new accounts. Invitation Code thread on Collatz website: https://boinc.thesonntags.com/collatz/forum_thread.php?id=1470

Contact the project admin Slicker to get an invitation code to register a new account.

Optimizing Collatz:
When you download the Collatz app you will have some empty gpu.config files in your Collatz folder. These files can be populated with values to optimize how Collatz Conjecture runs on your GPU.

These configs are generally configs that will maximize the output of your GPU. With increased GPU usage you may see a rise in GPU core and VRM temps, so it is a good idea to monitor temps for a few tasks.

More info on Optimizing Collatz can be found on the Collatz forum: Optimizing Collatz

Below is an example gpu.config from @fragamemnon.

gpu.config settings:

gpu.config for R9-290(x) This gpu.config also increased production on an NVIDIA GTX 980

Code:

Code:
verbose=1
kernels_per_reduction=48
threads=8
lut_size=17
sieve_size=30
cache_sieve=1
sleep=1
reduce_cpu=0
**This will be updated by the BOINC Editors from time-to-time.

might leave 2 threads free. 1 for the background system processes, and 1 whole core free for gpu. use one of the config files above too.
if its still not loading and you have done all the above. download process tamer from my site Process Tamer and set it to always make the collatz process a high priority. i use that on all my machines to give the gpu app a higher cpu process. tends to load the gpus better, been using it for years.

is the config file required to run solo_collatz tasks? I cannot seem to download anything but mini_collatz tasks, regardless of settings...

I cannot get solo_collatz tasks. The only reason I had mini units was because I checked all three at one point to see If the project would send me any WUs at all.

I have not tried a newer BOINC client. I will upgrade when I get around to it. Not really at the top of my list rt now. Thanks guys

Update: After upgrading the Boinc client on both rigs I have no issue getting gpu tasks for collatz. Now I can help with the PotM Yay!
