2nd decic search almost complete
The last of the WUs have been sent out and we are just waiting for them to be returned. We will post the consolidated results in the next few weeks. In the meantime, we have started issuing WUs for the next decic search, the one over Q(√2). Thanks!

Number Fields@Home at SpaceVision Conference
Come join Eric and me for a panel discussion on supercomputing at SpaceVision 2013 http://spacevision.seds.org/ on Friday Nov. 8th. We are looking forward to meeting with folks from SETI@home, MilkyWay@home and Asteroids@home to discuss distributed computing. This is your opportunity to meet with representatives of Number Fields@home and other Boinc projects. 5 Nov 2013, 19:53:45 UTC · Comment


Subfield #14 Complete
With only a handful of WUs left, I will declare subfield 14 complete. The bounded search has progressed to subfield 15 of 49, the one with discriminant 113. Thank you!

Search Status
The message boards have been quiet for some time now, so I thought I should give a quick status report. The 2nd search over Q(sqrt(5)) is about to enter the final stage. Since run times go up geometrically with discriminant, this final stage will take some time (~6 months). At the same time we will be picking off some of the low hanging fruit for the next search over Q(sqrt(2)), which will allow us to compute timing info for the later stages of that search.
Thank you for all your contributions!

First decic search complete
With only a handful of WUs left to go, we are declaring victory on the first search. This is a major achievement! In a nutshell, this search has obtained all degree 5 extensions of Q(i) (the Gaussian rationals) which are ramified at 2 and/or 5. The final tabulated results will be posted within the next couple of weeks. Thank you!

Thank you to all challenge participants!
This was a very successful challenge. A large chunk of the decic search was completed. In particular, the search over Q(i) was essentially finished, and inroads were made into the next 2 subfields. Thanks again for all your contributions!

Welcome Challenge Participants!
The team at NumberFields@Home would like to thank everyone participating in the latest challenge, and extend an extra special thanks to SETI.USA for organizing the event. With the first subfield nearing completion, the search over the 2nd and 3rd subfields has been opened up. Go get 'em!

For users who have been away for a while...
It was brought to my attention that some returning users were unable to connect to the project, probably because they are still using the old url.

So if you haven't visited in over a month, you may be unaware that we upgraded the project servers and have a different url now. If you are having problems connecting, then try reattaching to the project.

Thanks!

Problem with login page
It was brought to my attention that the login page was broken. I hadn't noticed since I was already logged in. If anyone has had problems logging in, it should work for you now. If you were already logged in like me and unaware of the issue, then you can ignore this message.

Server Outage on Friday May 3rd
We will be taking the project server down this Friday to perform the previously mentioned upgrade. We plan to take it down at approx 11am and hope to be back up by 3pm (AZ time). During this time, all project functionality will be disabled, including the main website and the forums.

Server Upgrade
We will be upgrading the server hardware in the next 2 to 3 weeks. This should be a smooth transition; however, any user still using the old url (stat.la.asu.edu) needs to change this to the new alias (numberfields.asu.edu/NumberFields). This can easily be done by removing/adding the project. The alias is in place now, so this can be done anytime before the upgrade. Thanks!

Decic search over Q(i) is making good progress.
The final level of the decic search over Q(i) has surpassed the 1/3 point. As mentioned previously, this is an extremely large search, so this is a worthy achievement. Only 2 more thirds to go. Congrats everyone!

Subfield #10 is now complete
Congratulations everyone! The bounded app has now crunched through subfield 10 of 49. We are moving on to subfield 11, the one with discriminant 133.

Another milestone reached
Good job everyone! Another level of the decic search over Q(i) has completed. We now move to the final leg of the search over Q(i). The final batch of WUs is targetting those fields with discriminant (2^29)*(5^18). This will be the biggest and baddest search so far, with a whopping 819200 WUs.

SPAM Attacks
We started getting an abundance of spam on the message boards this week. We have now configured the boards so that you need to have at least 100 RAC and Total Credit in order to post. This should have little effect on the legitimate users.

Another milestone reached
Another level of the search has been completed. We are now 1 step closer to finishing the Decics search over Q(i). The next batch of WUs is targetting those fields with discriminant (2^29)*(5^17). After that, we hit the (2^29)*(5^18) discriminants, which is the pinacle of the search over Q(i).

In addition to Q(i) there are 6 other subfields we need to do. I am starting to sprinkle some of those WUs in with the Q(i) work. These other subfields are expected to be much smaller searches, so the idea here is to pick off some of the easier targets while waiting for Q(i) to finish.

Planned Power Outage
They are making some electrical upgrades to the building housing our server. So there will be a power outage tonight, Aug 6th, starting around 5 pm (AZ time). Power should be restored by the next morning.

Sorry for the inconvenience.

Another subfield completed!
The bounded decics app has now completed subfield 7 of 49. Thanks for all your hard work!

Another milestone reached
The Decics search over Q(i) has now progressed to the highest discriminant level. It is now targetting those fields with discriminant having 2^29 as a factor. This final portion of the search will be the most challenging yet.

We couldn't have reached this milestone without our volunteers. Thanks to all of you!

And for those who are interested, the intermediate results have been uploaded. The link is on the main page.

Planned Power Outage
There was a planned power outage last night in the building housing our server in order to upgrade the network. This happened before I could post a news item, so I apologize for that.

There will be another planned outage tonight starting at 5pm AZ time. The server should be back up by Thursday morning. I am told all upgrades should be complete at that time.

Badges coming soon
We have decided to implement a badge system similar to other projects. I estimate it will take a couple weeks before it's fully working. It will be based on total credits, so it will include all credits earned since project inception.

To all Mac Users:
The Mac version is finally available! But think of this as a beta version. My wife just got a new Mac for work (the first Mac in this household), so I finally had access to a Mac on which to build the executables. It runs great for me, but I am not a Mac person, so I just hope it works for others (my biggest fear is the dependency on dynamic libs). It was built on the latest Mac OS X Lion (64bit).

Problem with client version 7.0.24 on ubuntu.
Word on the street is that this is happening on multiple projects, not just NumberFields. According to this link, version 7.0.26 may resolve the issue.

Extra Credit for GetDecics
In case you hadn't noticed, the latest batch of GetDecic WUs have much longer run times than usual (2 days on a fast host). Because of this, some users turned off this app in their preferences, in favor of the much faster GetBoundedDecics.

In the short term, we are more interested in the GetDecics results. So as an extra incentive to get users to run the GetDecics app, we are granting 50% more credits to all successful GetDecics results. This will be for a short time, until the current batch (14x121) is complete. For those who don't know how to select the app, goto your account and click "NumberFields@home preferences"; the rest should be easy.

Subfield 6 out of 49 is now complete
To recap, we have finished the subfields with discriminant 161, 157, 156, 152, 149, and 145. The next search is over the subfield with discriminant 141. Thanks for all your contributions!

A link for "Batch Status" was added to the main page (just under server status). I still need to add some more information to the table, but at least it should give you an idea of progress on the current data set.

The 5th subfield is now finished.
Once again, thank you to all our volunteers. We couldn't do this without you guys. I should also mention that the 2nd application has reached a new milestone, and has progressed to the next level of that search. For those who are interested, a list of the newest fields can be found via the link on the main page (the new fields are under the heading "decics with a quadratic subfield", near the bottom).

4th subfield out of 49 is now complete.
Actually there are a handful of work units that are slowly trickling in, but it's close enough to declare victory. The 5th subfield is close behind, about 80% complete. Thank you to all of our volunteers!

New application added to the project
The goal of this new application is to find all the imprimitive fields unramified outside of a given set of primes. We start with the set {2,5}.

During testing I noticed that this app had more consistent run times, around 20 hours per WU on my 2.6 GHz core i7. You will also notice quick jumps in the progress meter followed by slow periods. This is normal behavior.

Last of the complex subfields almost complete -- Good job everyone!
The search will now focus on the real subfields. For our chosen bound, there are 49 such subfields. The search starts with the one having discriminant 161.

New and Improved executable now available.
I fixed a rare bug that was causing about 1 out of every 1000 WUs to crash. Not a big deal, unless you were one of the unlucky ones to get such a WU.
The app also checkpoints more often now and gives finer resolution with the progress meter.

Thank you to all the new participants.
I was surprised to come home from vacation and see so many new participants. I only told a handful of people, but apparently the word got around. But this is good! Several issues have surfaced, but nothing too serious. Just a few general comments:
1. There can be large variations in run times between different work units. Each work unit represents a single instance of an outer loop variable, and it is hard to determine a priori how long the inner code will take for a given value of this variable. I have seen run times as long as 12 hours.
2. The windows version reports memory leakage whenever the executable is stopped. I believe this message is wrong, but it is annoying and I will try to find the cause of it.
3. The progress bar is not being implemented correctly. This causes the progress to appear stuck at 0% for the entire duration of the workunit.
