<a NAME="migration_help"></a>Migration Tools</h2>
|
||
|
|
The migration tools in the Zoltan library perform communication necessary
|
||
|
|
for data migration in the application. 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.
