Dr. Helena
I was wondering about which platform to consider for parallelization of
v.surf.rst , v.vol.rst etc. Till now I was thinking to do it for GPU and
Cell BE. If doing it in OpenCL or OpenMP will increase its usability ,
doing it on those platforms makes more sense. Currently I am planning to do
this on CUDA before gsoc starts in May.
@all: Please consider to add material as relevant here:
http://grass.osgeo.org/wiki/GPU
My plan for gsoc is to this in
OpenCL, so the project may be titled something like "Rewriting RST modules
of GRASS GIS in OpenCL" .
Maybe, to increase the possibility to be accepted (suggestion):
"Parallelization of GRASS GIS in OpenCL: The RST modules case"
or so...?
Has anyone signed up already for mentoring this project ?
Not that at know besides Helena's offer.
I am starting to do system of linear equations now on CUDA (for GPU) .
Please keep me posted about any information on other time consuming part of
RST modules.
(I take liberty to cross-post Helena's answer from the SOC list here,
for the record):

Do the system of linear equations first - it should help on several levels
because it will also make it possible to run the interpolation with fewer larger segments
and larger neighborhood reducing the instances when segments may be visible
in the resulting grid.
Computing grid may be time consuming for certain values of tension - I would have to look at it.
Checking the interpolating function at given points should be made optional - it depends on how
many points there are - it could take as much time as computing the grid.
Finding points should not take too much time unless the spatial distribution of points
is very heterogeneous, but I would have to look at it.
you can write me off-this list (maybe cc to GRASS dev list) as SoC list is mostly
to organize GSoC (at least that is how I understand its purpose),
