I have to do calculation on array of 1,2,3…9 dimensional vectors, and the number of those vectors varies significantly (say from 100 to up to couple of millions). Of course, it would be great if the data container can be easily decomposed to enable parallel algorithms.
I came across blitz++(almost impossible to compile for me), but are there any other fast libs that manipulate array of vector data? Is boost::fusion worth a look? Furthermore, vtk’s vtkDoubleArray seems nice, but vtk is lib used only for visualization. I must admit that having array of tuples is a tempting idea, but I didn’t see any benchmarks regarding boost::fusion and/or vtkDoubleArray. Just as they are not built for speed in mind. Any thoughts?
best regards,

Eigen, supports auto-vectorisation of vector on certains compilers (GCC 4, VC++ 2008).
