- Add support for fallback to previous coll module on non-commutative operations (#30) - Replace mutexes by atomic operations. - Use the correct nbc request type (for both ibcast and ireduce) * coll/base: document type casts in ompi_coll_base_retain_* - add module-wide topology cache - use standard instead of synchronous send and add mca parameter to control mode of initial send in ireduce/ibcast - reduce number of memory allocations - call the default request completion. - Remove the requests from the Fortran lookup conversion tables before completing and free it.
