Hi,
I am writing to find out if there is an open source C/C++ library
which allows one to supply a collection of particle (position +
additional channels like velocity, density, temperatures, vorticity
etc.) and builds/layout them in an Octree fashion and persisting them to
disk based on HDF5, which has corresponding methods to retrieve those
particles at non-empty leaf node, one node at a time.
I am looking for a memory efficient way to retrieve small chunks
(at known bounds, hence octree node) of a larger data sets which has
10^8 particles per time step on commodity PC machines with 8-16Gig of
RAM of which I targeting a memory use budget of 1-2Gig as there are
other geometry in memory.
Cheers
