New Version of MW@home for Mac (1.37)
Hey Mac Users,

I just released a new version of MilkyWay@home Separation that will run much faster on Macs. (Expect about a factor of 7-8 speed up). If you guys see any issues with the new application post them here.

I only released this new application under the official project and not the Modfit project since we are slowly phasing out the Modfit project.

Enjoy the weekend,

Running Modfit on MilkyWay@home
Hello Crunchers,

Now that MilkyWay@home Separation Modfit has been running for a year as a stable application, we are going to be releasing it as the official MilkyWay@home application under our main project. This means we will slowly (over the next month) be phasing out the dedicated Modfit project as it will be redundant. Additionally, this means some extremely old systems may no longer be supported on the MilkyWay@home project. These include Windows 32-bit systems, and very old (CAL) GPUs. If you are noticing compatibility issues with your system after we begin the change next week please post them here.

Thank you all for your continued support.


Modfit is now up and running on the main application. If you are seeing any issues please let me know here.

Server Maintenance Concluded
Hey Everyone,

Thank you all for your patience over the last week. I can say server maintenance is now concluded. The BOINC libraries on the server are up to date, and we have the newest available version of Ubuntu running on the server. We added HTTPS to the website so we recommend using that while you browse to best protect your personal information. Finally, maybe with the updated BOINC server libraries, the server will recognize some of the newer GPUs that support double precision (Not entirely sure about this point though).

Thank you everyone for your patience and happy crunching,

Server Maintanence
Hey Everyone,

We will be doing some server maintenance over the next day or two. This should not effect work unit generation, but the website may run slow or be down for short periods of time. Feel free to report any issues you notice by replying to this post.

We plan on rolling out HTTPS support for the site (I know we are a bit behind the times on this) and updating all of the BOINC libraries on the server (so maybe expanded GPU support) over the next couple days.

As usual with updates, we expect things to be a bit bumpy for the next couple days, please bear with us while we work through everything.

Thanks for your continued support.

Nbody Release 1.60
Hey All,

I just released a new version of Nbody, 1.60. In this version we completely changed the cost function. This is a function that is used in the histogram comparison algorithm. We discovered that the old cost function, which was supposed to allow us to retain the mass data in the normalized histograms, did not account properly for the amount of mass.

This was not a bug, but rather a change in the science behind the algorithm. We would not have rethought the algorithm without the results from MW@H.

As always, if there is any problem, let me know.

Thank you all,

Nbody Release 1.58
Hey All,

I just released a new version of nbody. This one fixes a bug that was found only after instituting the CM correction in the previous release. Let me know if there are any issues.

Nbody Release 1.56
Hey All,

I just released a new version of Nbody. This updates fixes some library issues we were having. Also, it adds a center of mass and center of momentum correction to the initialization (the added computation time is very negligible). We did this because we found that different seeds would produce a small random initial center of mass position and velocity. While it was not a large difference, we wanted it to be nonexistent.

I will be putting up some runs shortly.

As always, thank you all!

Nbody Release 1.54
Hey All,

I just released a new version of nbody, version 1.54. There are no major changes, just some minor bug fixes. There was a sampling bug in the velocity assignment which caused it to throw away more possible vels than it should. So the initialization is much faster than before. However, the results should be the same. But faster is always better!

Let me know if there is any issues with the new version/binaries.

Thank you!
