Bad Runs Put Up Over The Weekend
Hey Everyone,

You can expect to see invalid results and erros from any runs starting with ps_modfit* as they were a bad batch of runs. No more of these runs should be sent out as I have cancelled all workunits associated with these runs. I apologize for not catching this sooner.

Scheduled Server Maintenance Today
Hey Everyone,

Just doing a quick update to our optimization algorithms on the server. You should notice the site go down for a couple minutes and then come back up. This update is nothing that should effect the way you interact with MilkyWay@home.

nbody 1.64 release for Mac
Hey All,

I just released the newest version of nbody, version 1.64, for Mac single and multi-threaded. Please let me know if there are any issues.

PLEASE NOTE: We only have one mac machine for building and testing, meaning I had to test the binaries on the same machine that I built them on. So please let me know if anything strange crashing is seen.

Thank you all for your continued support,

Bad Batch of Runs
Hey Everyone,

Looks like I put up a bad batch of runs yesterday. Sorry about that. I took them down so they should be clearing out of the queue soon.

Expect errors from runs named:

Sorry again,

Hey Everyone,

I just released a Mac OS X version of Separation that should run on CPUs and GPUs (with double precision support). Please let me know if you have any issues with the Mac Separation application here.

New Release 1.64
Hey All,

I am about to release a new version of nbody. This version has a number of updates that expands functionality. I will make a blog post describing these updates soon.

We do not have mac binaries this time around. We are working on getting those. We also do not have 32bit support on either linux or windows.

The system I built the linux binaries on was Ubuntu 14.04 so there is the distinct possibility that they may not run on systems older than this.

I will put up some runs after releasing. Please let me know if there are any problems.

Scheduled Server Maintenance May 2nd
Hello Crunchers,

We have some scheduled maintenance for tomorrow, May 2nd. This maintenance will include the release of MilkyWay@home Separation version 1.46 as well as an update to our server code to support this new application version. If everything goes well we expect everything to be up and running within a half hour. If there are issues, I will be troubleshooting them until they are fixed.

I will make a new post tomorrow at the conclusion of the update and maintenance where you should post any issues you see.

Jake W.


Took down old runs to prepare for the new update. This should prevent seeing a bunch of errors when the new application comes out. Waiting on the work queue to clear out a bit before the new release.

Server Update
Hey Everyone,

I pushed a quick server update overnight tonight. This will probably result in the remaining:


results being crunched to return invalid results.

The new runs I put up:


should run and validate correctly.

As a status update for the Mac client and Linux client, I am still working on them, they are just slow going. I am working on finishing up some class work before the semester ends while also working on those applications so I will keep everyone posted on their progress.

Scheduled Maintenance Concluded
Hello Everyone,

Thank you all for your patience while the server was updated to allow for work unit bundling.

This update involved a new client and server code. Since our Mac we use for builds died, we do not have a Mac version of the client built. I plan to build one this weekend when I get access to a different Mac computer.

If you notice anything weird with validation, work unit generation, database stability, or client issues, etc. please report it here. I will work over the weekend to get them fixed if they show up.

Happy Crunching,
