Collatz: Collatz v3.15 CUDA Testers for Windows Needed

[RSS]

Version 3.15 of the Collatz CUDA application for Windows is now available in both 32 and 64 bit versions. It looks to be approximately 20% faster than v2.03. I'm looking for people to help test it on a variety of GPUs. If you would like to assist and post back your results, it can be downloaded at:Windows 32-bit: http://boinc.thesonntags.com/collatz...86__cuda42.zipWindows x64: http://boinc.thesonntags.com/collatz...64__cuda42.zipIt requires CUDA v4.2 drivers and must be installed as an anonymous application (a.k.a. using app_info.xml file). Also, optimization parameters have been moved from the command line to a config file so check the README.

Hey Slicker,

From what I was able to glean from the nVidia CUDA Toolkit 4.2 Archive (Link) only GForce driver versions 301.x and above are supported. Is this correct?

Looks like the testing has broken the feeding of ATI cards.

The ATI cards are now fixed.

The minimum nVidia driver needed for the CUDA 42 app is 301.42.

My mac was running it fine. Then the app update caused no new tasks to be available. So I just updated the CUDA driver to the latest. Now nothing but errors.
