Hi,
We would like to propose openmp optimizations in some parts of evas software backend OpenMP provides a scalable model for shared memory parallel applications. One of the construct enables parallelization of simple for-loops using 'pragma omp for'. We applied this pragma in one part of sample scaling in software backend where for-loop was used to run through the image. Running expedite on an Intel I3 machine with quad-core showed 48% improvement in "Image Blend Nearest Scaled" test-case. Test-case score went up from 128 to 190 This doesn't mean that every for-loop will be benefited by openmp. For-loop should have enough parallel-load and no dependencies so that threading overhead is hidden. Other areas of data-parallelism in evas can be analyzed and explored further. Openmp is supported in gcc since 4.2. Pragma based omp programs require a light-weight gcc omp runtime(libgomp.so) which is always packaged with gcc-runtime Requesting your feedback and comments Thanks, Krishnaraj ------------------------------------------------------------------------------ New Year.
