#1446: add --with-opencl support to ./configure<BR>
------------------------------------------------+---------------------------<BR>
Reporter: hamish | Owner: grass-dev@. <BR>
Type: task | Status: new <BR>
Priority: major | Milestone: 7.0.0 <BR>
Component: Compiling | Version: svn-trunk <BR>
Keywords: OpenCL, configure, smp, gpu, r.sun | Platform: All <BR>
Cpu: All | <BR>
------------------------------------------------+---------------------------<BR>
This is akin to task #657 (add --with-openmp support to ./configure),<BR>
which I still am very keen to see happen as we already have OpenMP-aware<BR>
code in trunk. See that report for a basic summary & philosophy of<BR>
approach.<BR>
<BR>
<BR>
For now the OepnCL support would mainly be used for Seth's 2010 GSoC<BR>
project to make r.sun use OpenCL, making it some hundreds of times faster,<BR>
which we'd like to merge into trunk in the near future.<BR>
<BR>
note that even if you don't have a fancy GPU the OpenCL spec allows you to<BR>
run the code on a multi-core CPU instead, so it's still nice. (maybe even<BR>
both multi-core CPU '''and''' GPU ??)<BR>
<BR>
<BR>
any help with the autoconf magic would be greatly appreciated.<BR>
<BR>
<BR>
thanks,<BR>
Hamish<BR>
