2019 Year in Review
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 be going on a 2 week vacation starting in a couple days. Internet access will be spotty, so I apologize in advance for any delays responding to the boards.

The rest of the project is fully automated and there is plenty of work in the backlog, so no worries there.

New GPU OpenCL versions available
I just deployed the windows AMD openCL version as a beta app. I will monitor results for errors, but please report any strange behavior.

I also deployed newer openCL versions for AMD linux and Nvidia windows. The openCL code had a couple minor tweaks; nothing major.

Batch plan
I know some of you like to know the batch plan, so here it is...

Batch 13x270 is nearing completion for subfield 3. After that, we will spend a week or two picking some of the low hanging fruit on subfield 7. Then it's back to subfield 3, batch 13x271. This is a very big batch, so I expect it to last until the end of December, possibly into January.

Entering Final Phase of Subfield 4
The final batch of subfield 4 is starting to rear its ugly head. This beast has 1.6M work units averaging about 2.5 hours a piece (on a 4GHz cpu).
