So another year has come and gone. It has been a very productive year. Here are the highlights:
1. The results for the septic search, which were completed in 2018, were accepted and published in The Journal of Number Theory.
2. A GPU app was developed for the decic search. Versions were eventually introduced for both Nvidia and AMD cards, and for both the Linux and Windows Platforms. During development, I discovered an opportunity for optimizing the CPU version which was subsequently implemented.
3. The decic app completed the search over ℚ(√-5) (subfield 5).
4. The decic app completed the search over ℚ(√-2) (subfield 4).
5. Searches were completed over the lower discriminant bounds for subfields 6 and 7.
6. The search over ℚ(√2) (subfield 3) progressed further into the higher tiers. We now only have 3 more tiers to go in that search.

Thanks everyone and have a wonderful New Year!

I will refer you to this thread:
https://numberfields.asu.edu/NumberFields/forum_thread.php?id=416

In summary, AMD changed something in their latest drivers which broke the app on windows (and potentially just on some cards).
The openCL code is stable on Nvidia and older AMD drivers. I adhered to the openCL standard to the best of my knowledge, so I am pretty sure the problem is with AMDs openCL implementation in their newer drivers.
