I'm a bit surprised about your qualifying of the openjpeg code base as
"spaghetti code". I've not spent a lot of time in it, just fixing a few bugs
here or there, but this was not my feeling at all. I can't remember having
seen goto's.
Anyway just seeing that gpu_jpeg2k is licenced unde
Hello Jürgen, thanks for your reply
I hoped that I could fix it.
I have to present a project (in which I was working with Gdal) at the end of
April. I think
that the most reliable solution is to replace the disk, right ?
Regards,
George

Hi Gpetr,
IMHO all that is evidence that the disk failures are in the binaries. It crash
while it still loading the shared libraries. Bus errors on Linux on Intel
point to paging problems. Unaligned accesses don't apply there.
And I'd expect the disk failures to spread and backup as much as I
I am interested in seeing an OpenCL JPEG2000 decoder/encoder developed. I have
a bit of experience writing OpenCL kernels. Please contact me if you need help.

Hey Seth,
I would love to have some help! Currently I have gathered all the relevant
open-source GPU accelerated code
I could find here:
https://github.com/OpenCodec
My plan is to port an existing CUDA jpeg 2000 library to OpenCL:

My library will be cal
GDAL core is mostly C++
but it is exposed thru a 'C' interface for stability reasons
e.g. the 'C API' is stable thru major releases whereas the
underlying implementation may change

Thanks, Norman! That is very useful.
I haven't decided yet whether to use C or C++ for the library language.
Is the gdal core C or C++? I am tending to C over C++, just for
portability.
But I want to avoid the spaghetti code I see in OpenJPEG.
Any comments on this?
Thanks again,
Aaron

Hello,
I recently started developing an open source jpeg2000 compression library
using opencl.
I would like to base the library design on the very successful gdal library
design.
Can anyone recomend any resources to help me to grok the high level design
of gdal?
Thanks so much,
Aaron
