If you tell OpenCL to target the CPU, it will produce a multiprocessor
implementation instead of GPU.

Even - good stuff!
Can you comment on the usage of openmp for multi-threading? Is the
multi-threading in gdal entirely based on pthreads (in linux)?
It's my understanding that openmp is much easier to manage but offers
less fine-grained control - is that required for multi-thread warping?
Of cou

Hi,
I've just commited in trunk the capability of doing multi-threaded warping.
There was already a -multi option of gdalwarp that was used to parallelize I/O
operations and warping computations. There's now a NUM_THREADS warping option
that can be used to set the number of threads to paralleli
I'm not confusing them.
What Petr was referring to is maptiler.com (MapTiler Cluster), which
doesn't seem to be open source.

You may be confusing
http://www.klokantech.com/maptiler/
with
http://www.maptiler.org/
http://code.google.com/p/maptiler/
The latter is FOSS.

Hi Petr,
AFAICS Maptiler is not open source, right?

hi Alex,
I am a beginner to learn gdal. I have a problem to read the metadata of
hdf5 file of Cosmo-skymed. I am working on visual studio 2010 in C# using
gdal dotnet dll.
I want to get some metadata item from the hdf5 dataset, the method like
"GetMetadataItem(string pszName, string pszD
Dear Yogesh,
we have developed highly optimized tiling and merging utility in C++
on top of GDAL. It is parallelized (multi-core CPUs) and can even run
on a cluster of computers with MPI. It is also producing tiles with
minimal size in PNG8/PNG8a or in JPEG. It has been used on very large
datasets
