PAMI and MPI header files and libraries
This appendix provides information about the Parallel Active Messaging Interface (PAMI) and Message Passing Interface (MPI) header files and libraries for the Blue Gene/Q system.
Blue Gene/Q applications
Blue Gene/Q applications run on the Blue Gene/Q compute nodes and can use PAMI or MPI software to communicate between application processes on different compute nodes.
There are six different builds of the MPICH2 software. Each build contains identical header files. Table C-1 describes the header files in the following directories:
•/bgsys/drivers/ppcfloor/comm/gcc/include
•/bgsys/drivers/ppcfloor/comm/gcc.legacy/include
•/bgsys/drivers/ppcfloor/comm/xl/include
•/bgsys/drivers/ppcfloor/comm/xl.legacy/include
•/bgsys/drivers/ppcfloor/comm/xl.ndebug/include
•/bgsys/drivers/ppcfloor/comm/xl.legacy.ndebug/include
