Overview<\/h2>\n

Zoltan<\/a> is a Parallel Partitioning, Load Balancing and Data-Management library from Sandia National Labs<\/a>. It provides a toolkit of combinatorial algorithms for parallel, unstructured, and\/or adaptive scientific applications. <\/p>\n

Version 3.83 is installed on the CSF. It was compiled using GCC Compilers 4.4.7 and OpenMPI 1.6.<\/p>\n

Restrictions on use<\/h2>\n

All users may access Zoltan. It is released under the BSD license – please see the COPYRIGHT_AND_LICENSE<\/code> in the installation for details.<\/p>\n

Please ensure you cite your usage of Zoltan as per the Zoltan citation page<\/a>.<\/p>\n

Compilation Info<\/h2>\n

The Zoltan library was compiled with the following settings enabled:<\/p>\n

\r\n--enable-zoltan-cppdriver --enable-mpi --enable-zoltan-examples\r\n<\/pre>\n
If you require other feature enabling in the library please contact us via its-ri-team@manchester.ac.uk<\/a>.<\/p>\n
Set up procedure<\/h2>\n
To access the software you must first load the correct modulefile. For compilation either modulefile can be used, however at runtime you must load the correct one – the underlying libraries are the same, but for MPI communications on multiple Infiniband connected nodes the modulefile has some hardware specific settings. <\/p>\n
Jobs requiring a single node (2 to 24 cores, via smp.pe):<\/p>\n
\r\nmodule load libs\/gcc\/zoltan\/3.83\r\n<\/pre>\n
Two or more nodes (48 cores+ (in multiples of 24) using Infiniband connected nodes via orte-24-ib.pe):<\/p>\n
\r\nmodule load libs\/gcc\/zoltan\/3.83-ib\r\n<\/pre>\n
These modulefiles load the openmpi 1.6(-ib) modulefiles for you.<\/p>\n
Running the application<\/h2>\n
The modulefile will set an environement variable named $ZOLTANDIR<\/code> which can then be used in your compilation process (e.g., in a Makefile) to access the header and library files:<\/p>\n
    \n
  1. To inform the compiler of the header file directory use: -I$ZOLTANDIR\/include<\/code> on the command line<\/li>\n
  2. To inform the compiler of the library files use: -L$ZOLTANDIR\/lib -lzoltan<\/code> on the command line<\/li>\n
  3. You should use the mpicc<\/code> compiler wrapper when compiling MPI code.<\/li>\n<\/ol>\n
    For further usage information consult the documentation.<\/p>\n
    An example is installed in the directory:<\/p>\n
    \r\n$ZOLTANDIR\/example\r\n<\/pre>\n
    You can copy this to your own area using:<\/p>\n
    \r\ncp -r $ZOLTANDIR\/example .\r\n<\/pre>\n
