D-Wave's AQUA (Adiabatic QUantum Algorithms) is a research project whose goal is to predict the performance of superconducting adiabatic quantum computers on a variety of hard problems arising in fields ranging from materials science to machine learning. AQUA@home uses Internet-connected computers to help design and analyze quantum computing algorithms, using Quantum Monte Carlo techniques. You can participate by running a free program on your computer.
AQUA@home is based at D-Wave Systems Inc., Burnaby, British Columbia, Canada.

Testing of a CUDA-enabled version of AQUA's application has started
25-May-2009
The AQUA@home project needs enourmous computing resources, so we have been working on using NVidia GPUs to reduce the running time of our application. We are happy to announce that version 3.00 of AQUA's application, supporting NVidia CUDA cards under Microsoft Windows, is now available for testing. Linux and Mac versions will follow in the next few weeks. We hope to gradually increase the performance of this version.

Habe mal das Forum durchstöbert, so wie es aussieht wird es wohl so schnell keine CUDA-Apps für die neuen Anwendungen geben, da für das Projekt mit der damaligen Cuda-App keine WU's mehr rausgegeben werden.

AQUA needs to set per-application limits, so hosts won't download too many tasks from each application. Doing so is possible only with 6.12.8 and higher BOINC client versions. Please consider upgrading your BOINC client.

A new test application
We'll be running a limited number of tasks belonging to a new application. It is only available for 64-bit Linux, and doesn't support checkpointing. It is a single-threaded app, and each run shouldn't take much longer than a few hours. Please login to you AQUA account and change your AQUA@home preferences if you don't want to run this app.

Ich hängs mal hier rein:

Aus BOINC Profit zu schlagen finde ich nun nicht so toll.

Hi Peter!

I'm Neo on the AQUA@home forum. Unfortunately, I ran a maintenance
script in the wrong directory on the AQUA@home server (on Monday, I
think), which then deleted a few critical BOINC config files instead of
the old files it was supposed to delete. After that, pretty much
everything slowly stopped working, and I didn't figure out what had
happened until the next day. To avoid more problems, we've turned the
server off until Boinc Admin gets back from vacation on Monday. He'd
probably (hopefully) know enough of what was in those configuration
files that we can start from a very old backup and make the necessary
updates to those. If not, there's very small chance that we can recover
the deleted files.

Morals of the story:
* Don't assume that there are recent backups
* Scripts that delete files en masse should require the user to specify
the directory or use an absolute address instead of assuming the current
directory

Hopefully we can recover, and hopefully people aren't too angry at us.
Sorry for the inconvenience.

Sincerely,
Neil

Na mal schaun was da noch zu retten ist. Hört sich für mich nicht wirklich gut an. Ich vermute da geht mit Sicherheit einiges an Arbeit verloren.

AQUA server is recovering from a serious problem
Last week the AQUA server had to be shut down because many configuration files were accidentally deleted. We are working on gradually repairing the damage, and will start submitting new work as soon as we are reasonably confident that everything is fine. This could take a few days. We believe the database is intact and no one has lost any credit. We apologize for any inconvenience this may have caused our volunteers.

Aqua ist wieder online und es sieht gut aus, das alles ohne Verluste wieder zum laufen kommt.

I just set the total_credit, expavg_credit, and expavg_time values for users, hosts, and teams to be the same as those of 19-June-2011.

I'll be releasing a few hundred FP and TEST workunits to test the credit system. Please note that BOINC's CreditNew is at work now, and the amount of granted credit will not be the same as before.

Die Credits wurden auf den Stand vom 19. Juni zurückgesetzt. Grund war wohl ein Bug (oder Feature?) in der BOINC-Server Software, wo dann für einige WU 5Mio Credits und ähnliches vergeben wurde. Der Fehler trat schon vor dem Ausfall auf, daher wurde ein so altes Backup eingespielt.

Der Projekt-Admin verlässt DWave, bisher ist noch nichts über einen Nachfolger o.ä. bekannt. Ich vermute aber mal, das es eine Weile keine Neue Arbeit geben wird.

Dear volunteers,

Your contribution over the last 3 years to the AQUA@home project was critical for us to perform immense computations necessary for the advancement of our science and technology. We have published several scientific papers reporting the results of those computations, including our recent publication in Nature. We made sure to acknowledge your generous contributions in those papers, as your help was vital. At this time, however, we no longer have large computations requiring the computing power of AQUA@home. We therefore have come to the decision to shut down AQUA for the forseeable future. Thank-you again for the selfless devotion of your time, patience, and computing resources to our effort to progress the field of quantum computing.

Sincerely,
Neil Dickson

Das wars für AQUA.

Jupp, sieht ganz danach aus. Der Quelltext der Aqua-Anwendungen wurde ja auch veröffentlicht, aber ich wüsste nicht welchen Nutzen es haben sollte das Projekt woanders nochmal aufleben zu lassen. Die wichtigen Erkenntnisse wurden ja (wie es aussieht) aus den bisherigen Berechnungen schon gewonnen.
