2019-06-08Performance optimizationsAdrian Kummerlaender
Starting point: ~200 MLUPS on a NVidia K2200 Changes that did not noticeably impact performance: * Memory layout AOS vs. SOA (weird, probably highly platform dependent) * Propagate on read * Tagging pointers as read / write only * Manual code inlining Changes that made things worse: * Bad thread block sizes The actual issue: * Hidden double precision computations => Code now yields ~600 MLUPS
2019-06-04Check whether hand-unrolling makes a differenceAdrian Kummerlaender
…it doesn't in this case.
2019-05-31Try out various OpenCL work group sizes using a Jupyter notebookAdrian Kummerlaender
This is actually quite nice for this kind of experimentation!
2019-05-30Collapse SOA into single arrayAdrian Kummerlaender
Weirdly the expected performance gains due to better coalescence of memory access is not achieved.
