Server Maintenance
Hey All,

For some reason I am not getting any return results from the Nbody app. The validator went down over the weekend and caused a huge backlog in the queue. I think this may be the issue as we have had something similar before. I am going to cancel the workunits in the queue and let it refill. If you see anything strange in the next 24 hrs with nbody workunits this is the reason.

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,
Sidd

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:
de_modfit_19_3s_146_bundle5_ModfitConstraintsWithDisk_1
de_modfit_19_3s_146_bundle5_ModfitConstraintsWithDisk_2
de_modfit_19_3s_146_bundle5_ModfitConstraintsWithDisk_3
de_modfit_19_3s_146_bundle5_ModfitConstraintsWithDisk_4

Sorry again,

Mac OS X Support For Separation
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.

[Edit]

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:

de_modfit_fast_19_3s_136_bundle5_ModfitConstraints3_5
de_modfit_fast_19_3s_136_bundle5_ModfitConstraints3_6
de_modfit_fast_19_3s_136_bundle5_ModfitConstraints3_7
de_modfit_fast_19_3s_136_bundle5_ModfitConstraints3_8

results being crunched to return invalid results.

The new runs I put up:

de_modfit_fast_19_3s_140_bundle5_ModfitConstraints3_1
de_modfit_fast_19_3s_140_bundle5_ModfitConstraints3_2
de_modfit_fast_19_3s_140_bundle5_ModfitConstraints3_3
de_modfit_fast_19_3s_140_bundle5_ModfitConstraints3_4

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.
