now are able to use the dynamic rules. Moreover, these rules are loaded only once, and stored at the component level. All communicators are able to use these rules (not only MPI_COMM_WORLD as until now). A lot of minor corrections, memory management issues and reduction in the amount of memory used by the tuned collectives. This commit was SVN r21825.
