Version 2.0.3 released, see Changelog.txt for the changes. In the following
some major enhancements:
- a new lock-free task scheduling for the ParallelFor has been implemented.
- defined ParallelFor and ParallelForReduce classes
- removed initial underscore in the preprocessor conditional guards in
order to be compliant to the C++ standard
- added the possibility to freeze and thaw all farm threads and then
restart a lower number of workers in a farm having a collector thread.
(see tests/test_stopstartall.cpp)
- fixed possible node termination problem (in case the freezing flag was set)
- ff_send_out_to modified in order to better work with ondemand scheduling
policy
- changed some int types with size_t, moved to svector whenever possible
- more possible combinations of farm, pipeline and feedback using
ff_minode and ff_monode
- better multi-input and multi-output support (ff_minode ff_monode)
