[Insight-users] GPU modules performance ITK 4.2

[Kris Zygmunt]

Hi Nadim,
     The GPU modules are faster, but how much faster will of course  
depend on your particular CPU and GPU configuration and your image  
sizes.  The GPU filter tests run both the CPU and GPU versions of each  
algorithm to ensure the GPU and CPU versions get the same results.   
The tests also record the time to execute both the CPU and GPU  
versions.  If you want to benchmark your machine, be sure to set both  
ITK_USE_GPU  and BUILD_TESTING to ON in CMake.  then build and test  
your GPU code by running the following from the top level of your  
build directory:
 >> make -j4 && ctest -R GPU

The performance numbers for each test can be found in  
<top_level_build_directory>/Testing/Temporary/LastTest.log
