is this project going to be open source, or you will keep it private ?

Alex,
What is the size of those matrices?
2014-05-08 15:56 GMT-04:00 Alexandre Bergel <alexandre.bergel@me.com>: My first thought would be to have some particular C routines to perform a transformation on a matrix. This would not be that difficult I guess. Well.. We have to see. We will likely enter the optimization phase in a couple of months from now.

So, Hannes may have been referring to optimizing the slow parts of the process in Native Boost directly instead of using an external library (if not, may I suggest it?). It is possible that just a few tweaks using Assembler in the process would get the speed up to an acceptable level, which would be determined by profiling the performance. Of course, that path requires someone on your project that can understand Assembler to get familiar with NativeBoost. -cbc

Currently, we have no preview of the Roassal book to share. Give us a couple of months :-)
Cheers, Alexandre

Interesting project, Alexandre!

Thanks Kilon for your nice words. Currently, AstroCloud is a bit slow. For example, loading this image takes much more than it should. For now, speed is not our priority. AstroCloud has to be fast and we will make it fast. Probably relying on external library is the way to go.
I assume you consider or have considered NativeBoost as well?
Just to give a bit more context about why we are doing AstroCloud. ALMA is the largest observatory on Earth, making it the largest astronomical project in existence (http://www.almaobservatory.org). This is what humanity has best to detect life outside Earth. ALMA is made of 66 high-precision antenas making it possible to see deep in the universe. Unfortunately, there is no good software to process these immensely complex pictures. Some tool suite naturally exist, but they were not made for ALMA, making these existing tools largely suboptimal to process complex picture of ALMA. Faviolaâs dream (and mine) is to produce a tool ready to be consumed by astronomers to process ALMA pictures. Faviola and I are currently seeking for additional resources on making this happen.
Regarding your help about documenting Roassal. It is very welcome! In one of my previous post, I said that 2014 will be the year of documenting Roassal. A book is on its way.
We will need people to review it. So thanks!
Preview of part of it on line?
Regards Hannes
