HP-MPI V2.3 for Linux Release Note

• High Availability (-ha) mode and the diagnostic library are not allowed at the
same time.
• MPICH mode and the diagnostic library are not allowed at the same time.
• HA with MPICH has not been tested.
• The diagnostic library strict mode is not compatible with some MPI-2 features.
• Some versions of Quadrics have a memory leak. The error received will look like:
0 MAP_SDRAM(140008800): can't map SDRAM 2824000(2404000) -
4020000(3c00000) (25149440 bytes) : -1
ELAN_EXCEPTION @ 0: 5 (Memory exhausted)
newRxDesc: Elan memory exhausted: port 2b200
This error can occur in following two cases:
— If the application calls MPI_Cancel repeatedly.
— If the application receives on MPI_ANY_SOURCE.
Set the environment variable LIBELAN_TPORT_BIGMSG to an appropriate message
size to resolve the resource issue. If this setting does not eliminate the error, contact
Quadrics for the fix.
