The routine <b><a href="../ug_html/ug_interface_mig.html#Zoltan_Migrate">Zoltan_Migrate</a></b> calls application-registered <a href="../ug_html/ug_query_mig.html#ZOLTAN_PACK_OBJ_FN">packing</a> routines to gather data to be sent to other processors. It sends the data using the <a href="../ug_html/ug_util_comm.html">unstructured communication package</a>. It then calls application-registered <a href="../ug_html/ug_query_mig.html#ZOLTAN_UNPACK_OBJ_FN">unpacking</a> routines for each imported object to add received data to the processor's data structures. See the <a href="../ug_html/ug.html">Zoltan User's Guide</a> for more details on the use of and interface to the migration tools. <p>In future releases, the migration tools will be updated to use MPI data types to support heterogeneous computing architectures. <br> <p> <hr WIDTH="100%"> <br>[<a href="dev.html">Table of Contents</a> | <a href="dev_fortran.html">Next: FORTRAN Interface</a> | <a href="dev_add_remap.html">Previous: Part Remapping</a> | <a href="https://www.sandia.gov/general/privacy-security/index.html">Privacy and Security</a>] </body> </html>
