We are very proud to announce our new set of optimized applications that will utilize AVX512 instruction set capable engines or to be precise those, which support AVX512dq instructions!

These applications are built to support both Linux and Windows 64bit architecture OS. The development of this version was possible thanks to the great help provided by ahorek's team!

Unfortunately it turns out that BOINC client applications for Windows still do not report all processor options to the server correctly. It is because of a known bug and even after a lot of discussions in BOINC's channels it's still there. The good news is that thanks to ahorek's team a bugfix was already accepted and merged into the BOINC's repository and the fix will be applied when client version 7.26.0 is released. Till then in order to run the AVX512 application you might need to switch to the Anonymous platform.

We'd like to remind you that while the Boinc server is capable of finding the best performing application for every particular system taking into account multiple factors, after a while it will start sending the right one for every particular system. Which means that even if your CPU supports AVX512dq instructions it still might receive FMA or AVX tasks and there is nothing to be concerned about. In such a case you might want to give a try to the so-called Anonymous platform where your client will explicitly request the AVX512 application.

Happy crunching and thank you for your support!
Asteroids@home's team

After a while, let me announce our paper based on the Asteroids@home project. It was published last year in the Frontiers in Astronomy and Space Sciences: https://ui.adsabs.harvard.edu/link_gateway/2022FrASS...909771D/PUB_HTML. We used ATLAS photometry and its bootstrap samples to derive rotation periods (no shape) for about 5000 asteroids.

The A@H project is currently processing data from ATLAS and Gaia together - that's what you are computing now.

Thank you all for your contribution!

P.S. Please ignore the previous news about the paper published in Astronomy and Astrophysics - its results were not based on A@H because, at that time, the server was down due to COVID and hardware issues. Sorry for the confusion.

Hi everyone,

We are proud to announce our new OpenCL applications for AMD GPUs!
Development process took some time but we finally managed to build it.
There are still many rough edges to be polished but thanks to you guys and to your feedback we'll continue to improve the code.

Linux application requires 64 bit OS with GLIBC v2.31 or higher and will run on most AMD Radeon GPU cards and some AMD Integrated Graphics with support of OpenCL 1.1 or higher.

Windows application requres 64bit Windows 10 or 11 and will run on most AMD Radeon cards and some AMD Integrated Graphics with support of OpenCL 1.2 or higher.

Happy crunching and thank you for your support!

Asteroids@home team

Hi everyone,

A new, 64bit, version of the Period search application for the Raspberry Pi was released today supporting aarch64 (armv8) architecture!

It will be interesting to get some feedback from you about how it performs as there still could be some issues to be solved.

Happy crunching and don't forget to use active cooling on your boards as the app can be very aggressive to the cores on times.

Cheers!
Georgi

We are happy to present you another set of applications that will utilize those CPUs, which possess the FMA instruction set!

It was built to support both Linux and Windows OS with 64bit architecture.
What must be taken into account with these applications is that depending on the CPU architecture, generation, model, version, speed and number of utilized cores, in some cases the FMA applications may run slower than the corresponding AVX ones because of how those instructions are handled on different architectures, details that I'll not going further here as there is a lot of information on Internet. Also, there could be another case using even the same FMA application. For instance, there could be a situation where on the same particular system, having your preferences restrict the use of just a single core of, let's say, an Intel(R) Xeon(R) W Processor Xeon W-2195 of the Skylake-W Architecture, that single core will run much faster, close to processors' Turbo frequency of 4.3GHz, than if your configuration allows the client to utilize let's say 12 or more cores. In the second case those cores will run close to the processors' base frequency of 2.3GHz, depending on their actual number, which will result drastically in lowering of the application performance. Take a look at this article where under the "Per Core Turbo Data" chapter you will find explanation about how the Turbo ratio limits works.

Still, while the Boinc server is capable of finding the best performed application for every particular system, taking into account multiple factors, and after a while it will start sending the right one for every particular system. Which means that even if your CPU is equipped with the FMA engine it still might receive an AVX tasks and there is nothing to be concerned.

So happy crunching and thank you for your support!

Radim Vančo (FoxKyong)

We are happy to present you our latest CUDA application v102.16!

It was built on top of CUDA's v11.8 SDK and thus it will be able to utilize the vast majority of cards with Compute Capabilities (CC) between 5.0 till 8.9 adding support for the Ampere & Ada Lovelace micro architecture, and all the Tegra & Jetson modules.
Of course, it comes with its own requirements for the driver's versions, depending on your architecture, as those before it.
In order your client to be able to receive it your computer must have one of the following Nvidia driver versions installed:

• For Linux x86_64 and Linux AArch64 >= 450.80.02
  
• For Windows x86_64 >= 452.39
  

(https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html)

Here is the list of supported by the v102.16 application GPUs by their CC provided by Nvidia.

So happy crunching and thank you for your support!

Radim Vančo (FoxKyong)

Hi everyone,

Server is finally up and running again after more than a year of being down. Everything is migrated to a new server and we hope it will run smoothly for a long time. There are still some minor issues but nothing crutial and all minor tweeks will be done during the time.
I would also like to thank to Georgi Vidinski who has helped with solving some problems.

Radim Vančo (FoxKyong)

Server is now ready to continue operating and there will be more workunits to send. But please be aware that it is still a temporary solution because new server won't by any sooner then on May or June and there still might happen some problems.

Radim Vančo (FoxKyong)

BOINC server is now running but it is still a temporary solution and there is still some additional work that needs to be done. New workunits should be available in a week or two.

Radim Vančo (FoxKyong)

Our new paper describing asteroid models reconstructed from ATLAS photometry has been accepted for publication in Astronomy and Astrophysics. The paper is available at arXiv. Thank you for your contribution!

Problem with uploading results to the server is fixed.

Radim Vančo (FoxKyong)

I am sorry for server outages which was happening recently. There were several factors which often caused lack of free space and some services crashed and I had to do an emergency shutdown on Saturday in order to fix everything so I couldn't inform you about it except for Twitter. There is still a hardware problem with one of servers which I have to fix but the server is not being used now so project should be stable now.

Radim Vančo (FoxKyong)

Today we released a new CUDA102 application v102.14 for both Windows & Linux.
A bug was fixed where application causes 100% utilisation of whole CPU core (thread in hyperthreaded CPUs)

Radim Vančo (FoxKyong)

We are proud to present you the new CUDA application that was released by our team yesterday.

What's improved?
- We've Added support for latest Compute Capabilities (CC). Application was built with latest CUDA SDK v10.2 adding support for latest NVIDIA devices with Compute Capabilities (CC). This build supports CC 3.0, 3.5, 3.7, 5.0, 5.2, 6.0, 6.1, 7.0, & 7.5 from Kepler, Maxwell, Pascal, Volta & Turing architectures and their GeForce, Quadro, NVS and Tesla series, but does NOT supports Tegra and Jetson SoC Series devices (CC 3.2, 5.3, 6.2 & 7.2) which are not subject of interest for this project.
- Fixed issue with special Light curves which has more than 1000 points.

There is no x86 (32bit) version. CUDA 10.2 supports x64 (64bits) operating systems only.

Side effects that could be observed because of the update.
If your client shows unusual "Remaining time" for the tasks you can follow these steps:
1) Set "No new tasks" from "Project" tab for "Asteroids@Home" project.
2) Then you need to finish your recently downloaded tasks.
3) When all are done and reported to the server please reset the project with 'Reset project' button at Project tab.

We also suggest to use the latest stable version 7.14.0 of BOINC client.

And last but not least we strongly suggest users, who has CUDA enabled devices to upgrade their drivers to the latest one. For today it is 442.74 - WHQL. You will find it here: https://www.nvidia.com/Download/driverResults.aspx/158759/en-us
For legacy drivers you will find drivers here: https://www.geforce.com/drivers/beta-legacy

Despite new CUDA application is release we will continue to support older devices with older drivers by the previous CUDA55 application.

I would also like to thank Georgi Vidinski who made this release possible.


Radim Vančo (FoxKyong)

We published hundreds of new asteroid models. The paper is available at arXiv and should soon appear in Astronomy and Astrophysics journal. Thanks a lot for your contribution and patience!

There is going to be a server maintenance on 07.10.2018. Servers will go offline at 15:00 UTC for about 15 hours.

Radim Vančo (FoxKyong)

A paper with new results has been accepted for publication in Astronomy and Astrophysics. The preprint is available at arXiv. The models will be available in DAMIT soon. Thanks for your contribution!

Hi, I am sorry for the current situation with a disk space. There is again no free space available on server so I had to shut down BOINC compoments and results are moving to a temporary storage. I will start BOINC compoments in two days (11.07.2018). If possible I will start it tomorrow depending on the file transfer status (I'll inform you on twitter when BOINC is fully running again).
We are also waiting for a new storage server which will solve the repeating disk space problem so I hope it will be very soon.

Radim Vančo (FoxKyong)

There is going to be a maintenance on 08.12.2017. Servers will be off for several hours. It will start at about 10:00 UTC.

Radim Vančo (FoxKyong)

There is going to be a big maintenance on 11.09.2017. It will take nearly 5 - 7 days. Servers won't be processing any work during maintanenace and most of the time might be offline.

Radim Vančo (FoxKyong)

Project server has unfortunately run out of space again very quickly but it will be running within about 8 hours. I am now moving results to another temporarily server.

edit:
Ok, I have to correct the deadline. There was some problem with speed during transfer so I had to run it over today. New deadline is till tomorrow. I am sorry about it but I have been monitoring it.

Radim Vančo (FoxKyong)

Server unfortunately run out of free space. It has been dealt with it and now it is running again.
I am sorry for very late response, I'll inform you as soon as possible next time.

Radim Vančo (FoxKyong)

A new application version with nvidia 1070/1080 support has been released.

Radim Vančo (FoxKyong)

Servers are again experiencing with free space issues. We need to move more data out so there will be no new work for one or two weeks and BOINC compoments will be disabled. Uploading results should work as the space will be freeing up. If there is enough space I will activate other BOINC compoments so that results could be validated.

Radim Vančo (FoxKyong)

There is going to be a bigger maintenance of server and network on 20.02.2016. It should start at 10:00 UTC and it will take propably 48 hours.

Radim Vančo (FoxKyong)

A paper Asteroid models from the Lowell Photometric Database describing the results obtained by A@H has been accepted for publication and is now in press in Astronomy and Astrophysics. There is a link to the public version of the paper at the Scientific Results page. All published models are also available through DAMIT. We thank all volunteers, these results are based on your contribution!

There is a new article Asteroids@home — A BOINC distributed computing project for asteroid shape reconstruction in Astronomy and Computing. You can see the article here, and here is in the archive.

Radim Vančo (FoxKyong)

We have published Progress Report #01 (September 2015) which summarizes what we have done since start the project.

Radim Vančo (FoxKyong)

Application for Android doesn't work on Android 5 at the present but we are working on a new version for Android 5 with HTC support.

Radim Vančo (FoxKyong)

Server has stable connection so it should work without interruptions now. It is also connected to 100 Mbit internet connection.

Radim Vančo (Kyong)

Server is going to be moved on 17.12.2014. It will be offline since 11:00 UTC, it will be online probably the other day. Another circumstance requires server to be offline every day between 19:00 - 09:00 UTC till January. I will write another info if anything change. I also write more information at forum about it.

Radim Vančo (Kyong)

We have added a new server for database. The project is currently running on two servers.

There is going to be server maintenance on 09.09.2014 starting at 08:00 UTC. It will take approximately 30 hours.

edit: The maintenance will be tommorow.

Radim Vančo (Kyong)

First, we are very sorry for this situation.

Admin of Asteroids@home (Kyong) went on vacation. He will be back on Sunday 17.8.

Big thanks for your patience.

Zdenek

There is going to be server maintenance on 28.06.2014 starting at 13:00 UTC. It will take approximately 30 hours.

edit:
Maintenance is done. Everything is running now.

Radim Vančo (Kyong)

There is another maintenance running. The last maintenance wasn't complete so I had to start it today. It will be done within 4 - 6 hours.

Radim Vančo (Kyong)

There a little problem with booting server due to bad configuration of Apache. Server is on-line again.

Radim Vančo (Kyong)

There is going to be another server upgrade on Monday 27.01.2014 starting at 07:30 UTC. RAID array and filesystem will have to be adjusted so it will take more time. Server will be offline approximately 3 days. I assume being online on Wednesday 29.01.2014 till 11:00 UTC. If there will be more delay I will inform about it on twitter.

Radim Vančo (Kyong)

I have upgraded BOINC server software to the latest source codes and did some additional changes.

Radim Vančo (Kyong)

Radim Vančo (Kyong)

There is a sudden maintenance so server components will be disabled until tommorow. I am sorry for that.

Radim Vančo (Kyong)

There are new updated applications released for almost all platforms. There are some improvements in CPU optimization (mainly for ARM processors) and a problem that caused some workunits didn't pass through validator was removed.

Radim Vančo (Kyong)

Migration of the server is finished. I am very sorry it took so long but there were more problems during the migration than I expected. Server should now be stable and I hope that there will be minimal failures in the near future.
I also changed deadline of all sent results to 15.10.2013 so you shouldn't lost any of your work done by the migration.

Radim Vančo (Kyong)

New date of server migration is planned on friday 20th. It should start at about 07:30 UTC and supposed needed time is about 6 - 8 hours.

Radim Vančo (Kyong)

Server migration is probably going to perform on friday 13th. It should start at about 07:30 UTC and end at about 13:00 UTC but it can take much longer, so server could be offline until the evening if the migration is slowly or any other problem happens.

Radim Vančo (Kyong)

New improved versions of SSE2 and SSE3 has been released for 32 and 64bit linux and windows.

Radim Vančo (Kyong)

I am very sorry for troubles with server. Server got to its limit and his capacity was very overloaded so there were many failures. The failures are partially solved now, database is temporarily moved to another server and its load is very decreased so server is functional now. Also there is going to be new server soon so I will notice again about the specific date when there is migration going to be.

Radim Vančo (Kyong)

There is a maintenance being in progress, server will be stopped for a few hours. It should be working again at about 18:00 UTC.
