RawTherapee bekommt OpenMP Unterstützung [Update3]

leave a comment »

Gestern hat Gabor den ersten Teil der OpenMP Unterstützung für RawTherapee in das Mercurial Repository hochgeladen.

Ich habe noch keine Tests gemacht, aber meiner Erfahrung mit OpenMP nach wird es rechenintensive Schritte wie das Demosaicing sicherlich gut beschleunigen. Vielleicht komme ich heute Nachmittag dazu, ein wenig zu testen.

Update: Da der erste Teil der OpenMP Unterstützung noch nicht die Demosaicing Algorithmen betroffen hat, fallen die Verbesserungen eher moderat zwischen 5 und 15% aus, aber schneller ist immer gut, v.a. da OpenMP keine Änderungen am Code erfordert. Hier nun die Zahlen:

10 Bilder, 64bit Ubuntu, Intel Q9550 4×2,83GHz, gcc 4.5

Ohne OMP:
DCB: 239s
HPHD: 108s
EAHD: 211s

Mit OMP:
DCB: 226s
HPHD: 91s
EAHD: 198s

Obwohl die verschiedenen Demosaicing Algorithmen noch nicht angepasst wurden, unterscheiden sich die Beschleunigungen doch deutlich. HPHD profitiert am meisten.

Update2: Der zweite Teil der OpenMP Unterstützung ist nun angekommen. Die Zahlen dazu gibt es heute Nachmittag oder morgen früh.

Update3:

DCB: 221s
HPHD: 80s
EAHD: 198s

I want to apologize to all my readers. Obviously WordPress considered my dcraw advertisement links a violation of their TOS and shut down my blog without noticing me…

So maybe I’ll find another way for you to support opensource projects or you have to donate for yourself. Sorry for the inconvenience.

Mein Flickr Pro Account läuft demnächst aus, sollte also irgendjemand hier das Bedürfnis haben, mir etwas Gutes zu tun, dann würde ich mir eine Verlängerung wünschen 🙂

My Flickr Pro account is going to expire soon, so if someone wants to donate a year, I’d be very happy about that 🙂

RawTherapee wird open source!

with one comment

Vorhin habe ich die freudige Nachricht gelesen, dass RawTherapee, der meiner Meinung nach beste RAW Converter für Linux und Windows, bald unter GPL stehen wird. Danke an Gabor, danke auch an das Entwicklerteam.

Ich hoffe, dass die Entwicklung dadurch einen immensen Schub bekommen wird und die Software zu dem Standard Tool für RAW Bilder wird, was einst Firefox auf dem Browsermarkt geworden ist.

Libre Graphics Meeting 2009

with one comment

Wie schon die letzten Jahre, steht wieder das LGM an, eine Entwickler- und Benutzerkonferenz, auf der sich Entwickler und Nutzer der prominentesten Open Source Grafikprogramme treffen, GIMP, Krita, Inkscape, Blender, Scribus und noch weitere. Da die Entwickler in ihrer Freizeit an diesen Projekten arbeiten und somit daran nichts verdienen, bitten die Organisatoren um Spenden, die die Anreisekosten decken.
Dazu wurde, wie schon letztes Jahr, eine Pledgie Seite eingerichtet, dort kann man auf einfachsten Weg seinen Teil beitragen kann. Ich würde mich freuen, wenn dies viele meiner Leser, die Open Source Grafikprogramme einsetzen, tun, seien es 5, 10 oder 15$, jeder Betrag ist willkommen und wird dringend benötigt.

————

Like the last years, 2009 will feature the LGM, a developer and user conference of the biggest open source graphic programs like, GIMP, Krita, Inkscape, Blender, Scribus and many others.

As those developers work on those projects in their sparetime and don’t earn much by doing so if at all, the organisation is asking for donations to support travel costs.
Therefore a pledgie page was set up, to offer an easy way to donate money. I’d be happy if my readers would donate to this cause when using any open source graphic programs. 5, 10, 15$ or more are very appreciated.
