Dann aber runter mit deinem Cache! Ich hatte vorhin 700 WU's, boinc.exe hatte 99% CPU-Auslastung und 130mb RAM. Eine WU dauert nämlich rund 0,3 Sekunden. Da kannste dir vorstellen, was im Upload/Download-Bereich so abgeht ...

0,3 sekunden ? Das ist doch unlogisch...ich würde nie solch Winzdinger verschicken...

Wenns so weiter geht, werde ich den Rekord der 153h noch brechen, meine liegt jetzt bei 127h, hoffentlich passiert jetzt nichts, keine Checkpoints, dann wären nochmal 4-5 Tage futsch :?

Mit der neuen App sollte man aufpassen, da ein "suspend" einer WU evt. Folgen wie keine weitere Berechnung mehr oder ähnliches passiert.

January, 18
We've started to test the additional scientific application rcross. It has checkpoints and it updates the progress bar. We develop under Linux and the first test version is only available for Linux crunchers because it doesn't make sense to compile the first intermediate test versions for all platforms. Currently we have about 10 workunits for rcross
Neu Applikation nur für Linux erstmal inkl. Checkpoints, Fortschrittanzeige und 10 Test-WUs.

Mal ein kurzer Statusüberblick und wie es weitergehen soll:
In zwei bis drei Wochen sollten die langen tuesdrei erledigt sein. Dann werde ich ein paar Tage lang nur RCross rechnen lassen, während die tuesday's ausgewertet werden. Und dann können wir erst mal grob schätzen, wieviel tuesday's wir in wednesday's splitten müssen und wie lange das ganze noch laufen soll.

Ein zweites Projekt 'sudoku' ist übrigens gerade in Entwicklung. Es wird später parallel zu RCN installiert.

Der Projektadmin hat evt. eine Möglichkeit gefunden, in der tcape app checkpoints+Fortschrittanzeige zu integrieren, wird aber noch etwas dauern.

So, und nun schon bald das nächste Projekt:
June 23, 2007
Good good good news: 2 x Xeon 3.4 GHz, 5 x SCSI 146 GB, 4 GB RAM, ... Yes, due to the successs of RCN we managed to get a second server. It is already in my office and awaits its boincification. It will be used as server for our upcoming project ''SUDOKU'' where we will search for the smallest possible start configuration of the game. The tests for the new project might start in one or two weeks. I will keep you informed. Btw: Our users have established a new record: Yesterday they contributed 3 cpu years!

Auf zur letzten? Runde:
1) The next generation of cape-crossing workunits is
online now. We have 525666 of them. The question "how
much work is left" might arise now, and the anwer is:
As soon as the W4's are crunched we are done! However,
it is very unlikely that all W4's can be solved
completely and probably some thousand will remain to
be splitted into W5's.

Nächste Runde:
January 3, 2008
Another bunch of workunits is ready: 764.000 workunits, named ''W6...'' are online to feed your hungry machines. As we get closer to the project's target the problem gets harder and harder. Therefore the maximum running time of the workunits is 10 hours now. If you have still W5's you can cancel them as their range of numbers is included in the W6's. However, if you crunch them you will get your credits.

The W6 workunits were too large. Therefore they have been canceled and replaced by 2688999 W6q workunits (q means quarter, every W6 has been replaced by 4 W6q). If you still have W6 workunits you can cancel them or crunch them. You will get your credits.
Die WUs wurden etwas kleiner gemacht, W5 und W6 sollte man abbrechen.

Please cancel all the old workunits, currently we crunch the W0q series for testing the system. I will inform you asap when the error is eliminated
Da die alten einen bug hatten, werden jetzt neue getestet.

Solved. The error rate is below 7 percent again. This is quite normal and is due to misconfigured hosts or workunits that have been canceled via GUI.
The new series of workunits is called "w6r...". Please crunch only the w0q and the w6r (they are the new w6q's which were partly defect). If you still have older workunits, please cancel them.

Best
Bernhard
