GPU Issues Mega Thread
Hey everyone,

I am going to spend some time specifically looking into the GPU issues for the next couple days. Can everyone please post the exact issues you are having here? This includes quotes of the error messages you are seeing and any other information you think is useful. I've been going through old forums posts trying to decide where I think the problem is and I am still unsure where the problem is.

Science Page Now Available in Russian
Hey Everyone,

One of our fellow crunchers "Shmya-2" was kind enough to take the time to translate our science page to Russian. For those of you interested in giving it a read please visit here.

Thank you Shmya-2.

MilkyWay@home Server Maintenance
Hey Everyone,

Sorry the server was down for so long. I upgraded the operating system on the server yesterday and some of the upgraded programs did not want to play nice. Everything seems to be working well now.

If you see any persisting errors on the website, or coming from BOINC please post them here.

Windows 32-bit Application Release
Hello Crunchers,

We now have an officially supported Windows 32-bit application for CPU and GPU crunching. If you have any issues with the application please post them here and I will do my best to address them.

Sorry this took so long,

Windows 32-bit Application Progress Update
Hello Cruncher,

I just wanted to let everyone know that we have just set up a test platform for Windows 32-bit which should allow us to begin work on building and testing a 32-bit Windows application for Separation with Modfit. I make no promises that this will be a quick process, but it is something we are working on.

Happy Crunching,

Jake

[edit]
Update: I currently have a CPU version of our Windows 32 bit application compiled and initial tests look good. I will be working on the Windows 32 bit OpenCL application for the rest of the night. Hopefully, that will be compiled by morning. If everything goes well in testing, I suspect maybe a release of a Windows 32 bit application for Separation on Monday.

Update2: I currently have both a CPU and GPU version of MilkyWay@home compiled for Windows 32-bit. I plan to do some extensive testing of the applications tonight and will hopefully release them tomorrow, assuming they are as intended. Sorry they are coming a day late, the GPU application proved to a bit tricky to get working.

New Look for the Science Page
Hello Crunchers,

I would like to announce a new look for our science page. In an attempt to bring the style of the science page more in line with that of the rest of the webpage, we did a visual overhaul of the page.

In addition to the visual reformatting, I did a lot of back-end reformatting of the page which should allow us to more easily edit it in the future. This is just the first step in our attempt to make the science page more interesting, complete and reader friendly. Look for a content update on the page to come in the new few weeks.

If you guys have anything you would like to see included on the page, or any general questions about the science we are doing with the project, feel free to post them here.

Happy Crunching,

Jake

No More Work From Modfit Project
Hello Crunchers,

We will no longer be sending work units out through the Modfit project. You will still receive work units tagged as Modfit, but they will not be coming from the official MilkyWay@home application.

Thank you for your patience during the transition.

MilkyWay@home Linux 32-bit Version 1.37
Hey everyone,

I recompiled the CPU version of the Linux 32-bit application as a static binary to resolve some library issues some users were encountering. If you guys see any problems with this application please post them here.

Happy Crunching,

Nbody Release 1.62
Hey All,

I just released a new version of nbody, v1.62. In this release we did a few things:

We realized that different platforms were giving slightly different results. This was a problem as it would throw off the search algorithm and also may cause validation issues. Turns out there were an number of reasons for this. One was that the likelihood calculation was performed using single precision on a double precision application. So we changed it to be a double precision calculation.

Also, and most prominently, we realized that the windows command prompt and unix terminal read in inputs with different precision. One would cut the value of after about the 10th decimal place. This mean the actual input parameters were slightly different! Therefore, we forced the rounding of the input parameters after the 9th decimal place. That seemed to do the trick mostly.

Finally, we realized that our building mechanism was not building linux binaries statically. When we tried with our current mechanism we ran into a can of worms known as seg faults. It was a nightmare trying to find it so we decided to temporarily switch our building mechanism. I tested them on all our computers and it seems to work. But, as always, let me know if something goes awry.



Thanks everyone for your continued support!
