Collatz Sieve 1.10 Released for Windows
While trying to port the new sieve app to OS X, I discovered a couple bugs, one of which was causing the 64-bit apps to fail. That has lead to releasing v1.10 for both 32 and 64 bit Windows. 19 Aug 2015, 16:03:27 UTC · Comment

SSL Certificate is Expired
Startcom won't renew the SSL certificate until Google deems the site safe for 90 days. Unfortunately, there are 30 more days to go since I removed the apps that several anti-virus applications incorrectly identified as a trojan. 14 Aug 2015, 23:58:32 UTC · Comment

Collatz Sieve 1.08 Released for Windows
The 1.07 added variable sieve sizes but introduced a bug in the kernel that was causing it to returning results outside the bounds of the numbers being checked which results in them being invalid. Version 1.08 should fix that problem. Please let me know if you run into any difficulties. 14 Aug 2015, 23:55:30 UTC · Comment

Collartz Sieve v1.07 released for Windows
A new version of the Collatz Sieve application has been released for Windows. The Collatz Sieve app is still listed as a beta/test application so you will need to check that in your preferences in order to get work.

I added a sieve_size parameter to the config file in version 1.07 which controls not only the sieve size used but also affects the items per kernel. I also modified the default values to those found to work on all of my various nVidia and AMD gpus with 99% GPU utilization and reasonable video response. Macintosh and Linux versions should be available sometime next week.

New Linux 64-bit CUDA App
I built a new Linux 64-bit app (version 6.07) which uses CUDA 5.5 and __should__ be statically linked. Hopefully, this will eliminate the glibc errors some have seen. This version also includes the bug fix for CPU validation not matching the GPU results. Once I see valid results for this version, I will build and add the 32-bit CUDA for Linux versions. 8 Jul 2015, 16:30:49 UTC · Comment
