EnglishThis paper presents PIT, a library for the parallelization of irregular problems on distributed memory architectures. All the strategies underlying the definition of the library can be expressed in terms of operations on a PITree, a parallel version of the tree data structure oriented to irregular problems. We consider the application of PIT to two well known irregular problems: adaptive multigrid and hierarchical radiosity methods. Performance figures that prove the effectiveness of PIT are presented.
