PhD Thesis
Hey Everyone,

I just wanted to updated everyone on some of the current scientific work and results coming out of MilkyWay@home. These results can be found in my PhD thesis which I posted here.

The major result from this work is that we have mapped 7 stellar streams in the Milky Way halo. We believe two of these streams are likely to newly discovered streams.

These results would not have been possible without the contributions of the MilkyWay@home volunteers. Looking forward we hope to improve our mapping algorithms to find map new stellar streams and better fit those we have already found.

Thank you.

New nbody runs July 2
Hey All,

I just put up some new nbody runs. They will be the first to run off the new version (v170). I waited some time to put these up so the queue would clear out of the old workunits.

Please let me know if anyone encounters any issues with these runs.

As always, thank you for you continuing support,

Nbody 1.70 release
Hey All,

I just released a new version of Nbody, v1.70. There were very minor but necessary changes. I am hoping the transition goes smoothly.

As always, please let us know if there are any issues.

Thank you for your continuing support,

New Separation Runs 7 May
Hey Everyone,

I just put up a bunch of new runs named:

de_modfit_XX_bundle4_4s_NoContraintsWithDisk_1

where XX goes from 09 to 23.

Let me know if you see any issues with these runs here.

Thanks everyone,

Improved Database Stability
Hey Everyone,

I made some more configuration updates to improve database stability. If you notice any database errors, please post about them here.

New Runs
Hey Everyone,

I just put up 14 new runs. These are de_modfit_XX_bundle5_NoContraintsWithDisk_1 where XX runs from 09 to 23. Each of these is using a different parameter and star file so its very possible that there was some human error on my part putting them up. They were all tested beforehand but if you see any issues, please let me know with the name of the run that's giving you trouble.

Some of these runs have some extra calculations due to the run requirements so their runtimes will vary slightly. The credits should scale accordingly.

Scheduled Server Maintenance 3/27
Hey everyone,

We are going to do a quick hardware upgrade for the server. We will be down for the next hour or so. Sorry for the inconvenience.


Jake

[Edit]

This down period is concluded. We couldn't finish the upgrade due to a bad CPU slot on the motherboard. We are going to defer server upgrades for a while until we decide if it is worth it to replace the motherboard.

Thank you all for your patience,

Jake

Testing Some New Plan Classes
Hey Everyone,

I am going to try changing the GPU plan classes to reduce workunits sent to users without double precision gpus. If you notice any issues on your end, please let me know.

Thanks,

Removing Hosts With High Error Counts
Hey Everyone,

I am going to be issuing suspensions to 8 hosts with extremely high error counts (over 1000 in their recent history). If you own one of these hosts and are unhappy with the suspension, please message me and we can discuss removing the suspension.

This is a temporary solution until I can implement a more automated suspension system with occasional retesting of hosts to see if they have been fixed.

Any discussion about how to best implement an automated algorithm can go here and I will attempt to keep up.

Jake

Edit:

I added a feature to determine if one of your hosts is suspended at a quick glance. Any of your suspended hosts will show up highlighted in red on the "computers on this account" page in your account information page. These hosts will not show up as red to anyone else and only you will know if you are suspended. 7 Mar 2018, 19:55:44 UTC · Comment

Reverting Change to Remove Unreliable Hosts
Hey Everyone,

I am going to be reverting the change to use the built in BOINC use reliable hosts option. It seems to be having unintended consequences to the usability of the project for some users.

In the future, Sidd and I will look into manually removing the worst offenders who are sending back erroring workunits.

For anyone effected, I apologize if you haven't been able to crunch for us recently.
