Finally recovering from hard drive crash.
The crash was so bad that the database could not be repaired. The first non-corrupted backup was 2 days old. Restoring from there seems to have worked but there are probably issues since it will be out of sync from results that get returned.

I pushed the deadline back another 4 days for any outstanding WUs to give people time to return them, but anything issued 2 days prior to the crash will not be in the database so I am not sure how that will play out.

Sorry for the inconvenience!

2020 Year in Review
The 2020 shit show has come to an end. Here are the NumberFields highlights for the year:
1. The miscellaneous tables were completed. Except for the {2,5} case, this gives the fields for all
imprimitive decics ramified at {p}, {q}, or {p,q} for all primes p < q < 13.
2. Finished many of the lower tiers for the search over ℚ(√-10) (subfield 7).
3. Completed a few more batches for the search over ℚ(√2) (subfield 3), essentially leaving the final monster batch. At our current rate, this batch will take approximately the first half of 2021 to complete.
4. The CPU apps (for 64bit machines) were improved to give an average speed increase of about 35%. Improved GPU apps will be rolled out in the near term.

Thanks everyone for your contributions and have a wonderful New Year!

Server problems this past weekend
We had what we thought was a hard drive crash - the drive went into a read-only state and the server crashed. It would not even allow a remote reboot. We finally got someone in there this morning to do a hard shutdown.

The system came back and appears to be working now. But we will continue to keep an eye on it.

If you are like me, you will have a bunch of WUs that need uploading. Please have patience as everyone will be uploading at the same time, so there might be delays.

New and improved apps coming soon
I have made some improvements to the cpu code. I am seeing somewhere between 30% and 40% speedup, depending on the case.

I have deployed the new executable for 64bit linux. I am currently trying to get it to build for 64bit windows. I hope to have that ready by tomorrow sometime.

The next step is to use these same tricks on the GPU versions. GPUs can be very finicky, so this might take several weeks before I have something worthwhile.

Should the fixed credits be higher?
I have had a couple people mention that the fixed credits should be higher. I tried to set the credits to be in line with the cobblestone definition, but it's possible I missed the mark.

I will wait for feedback before making any changes. Please share your credit opinions.
