- Updated to 1.2p1 release from OFED 1.4 GA
- Fix shared-memory communication issue for AMD Barcelona systems.
- Ignore the last bit of the pkey and remove the pkey_ix option since the
index can be different on different machines.
- Fix data types for memory allocations. Thanks for Dr. Bill Barth from TACC
for the patches.
- Fix a bug when MV2_NUM_HCAS is larger than the number of active HCAs.
- Allow builds on architectures for which tuning parameters do not exist.
- Always build and install mpirun_rsh in addition to the process manager(s)
selected through the --with-pm mechanism.
- Cleaner job abort handling
- Ability to detect the path to mpispawn if the Linux proc filesystem is
available.
- Added Totalview debugger support
- Stdin is only available to rank 0. Other ranks get /dev/null.
- Add sequence numbers for RPUT and RGET finish packets.
- Increase the number of allowed nodes for shared memory broadcast to 4K.
- Use /dev/shm on Linux as the default temporary file path for shared memory
communication. Thanks for Doug Johnson@OSC for the patch.
- MV2_DEFAULT_MAX_WQE has been replaced with MV2_DEFAULT_MAX_SEND_WQE and
MV2_DEFAULT_MAX_RECV_WQE for send and recv wqes, respectively.
- Fix compilation warnings.
- Properly handle the scenario in shared memory broadcast code when the
datatypes of different processes taking part in broadcast are different.
- Fix a bug in Checkpoint-Restart code to determine whether a connection is a
shared memory connection or a network connection.
- Support non-standard path for BLCR header files.
- Increase the maximum heap size to avoid race condition in realloc().
- Use int32_t for rank for larger jobs with 32k processes or more.
- Improve mvapich2-1.2 bandwidth to the same level of mvapich2-1.0.3.
- An error handling patch for uDAPL interface. Thanks for Nilesh Awate for
the patch.
- Explicitly set some of the EP attributes when on demand connection is used
in uDAPL interface.
- Scalable and robust daemon-less job startup
- Enhanced and robust mpirun_rsh framework (non-MPD-based) to
provide scalable job launching on multi-thousand core clusters
- Available for OpenFabrics (IB and iWARP) and uDAPL interfaces
(including Solaris)
- Adding support for intra-node shared memory communication with Checkpoint-restart
- Allows best performance and scalability with fault-tolerance
support
- Enhancement to software installation
- Change to full autoconf-based configuration
- Adding an application (mpiname) for querying the MVAPICH2 library
version and configuration information
- Enhanced processor affinity using PLPA for multi-core architectures
- Allows user-defined flexible processor affinity
- Enhanced scalability for RDMA-based direct one-sided communication
with less communication resource
- Shared memory optimized MPI_Bcast operations
- Optimized and tuned MPI_Alltoall
- Change the default MV2_DAPL_PROVIDER to OpenIB-cma
- Remove extraneous parameter is_blocking from the gen2 interface for
MPIDI_CH3I_MRAILI_Get_next_vbuf
- Explicitly name unions in struct ibv_wr_descriptor and reference the
members in the code properly.
- Change "inline" functions to "static inline" properly.
- Increase the maximum number of buffer allocations for communication
intensive applications
- Corrections for warnings from the Sun Studio 12 compiler.
- If malloc hook initialization fails, then turn off registration
cache
- Add MV_R3_THESHOLD and MV_R3_NOCACHE_THRESHOLD which allows
R3 to be used for smaller messages instead of registering the
buffer and using a zero-copy protocol.
- Fixed an error in message coalescing.
- Setting application initiated checkpoint as default if CR is turned on.
- Enhance udapl initializaton, set all ep_attr fields properly.
- Fixing a bug that miscalculates the receive size in case of complex
datatype is used.
- Minor patches for fixing (i) NBO for rdma-cm ports and (ii) rank
variable usage in DEBUG_PRINT in rdma-cm.c
- Message coalescing support to enable reduction of per Queue-pair
send queues for reduction in memory requirement on large scale
clusters. This design also increases the small message messaging
rate significantly. Available for Open Fabrics Gen2-IB.
- Hot-Spot Avoidance Mechanism (HSAM) for alleviating
network congestion in large scale clusters. Available for
Open Fabrics Gen2-IB.
- RDMA CM based on-demand connection management for large scale
clusters. Available for OpenFabrics Gen2-IB and Gen2-iWARP.
- uDAPL on-demand connection management for large scale clusters.
Available for uDAPL interface (including Solaris IB implementation).
- RDMA Read support for increased overlap of computation and
communication. Available for OpenFabrics Gen2-IB and Gen2-iWARP.
- Application-initiated system-level (synchronous) checkpointing in
addition to the user-transparent checkpointing. User application can
now request a whole program checkpoint synchronously with BLCR by
calling special functions within the application. Available for
OpenFabrics Gen2-IB.
- Network-Level fault tolerance with Automatic Path Migration (APM)
for tolerating intermittent network failures over InfiniBand.
Available for OpenFabrics Gen2-IB.
- Integrated multi-rail communication support for OpenFabrics
Gen2-iWARP.
- Blocking mode of communication progress. Available for OpenFabrics
Gen2-IB.
- Fix for hang while using IMB with -multi option.
- Fix for hang in memory allocations > 2^31 - 1.
- Fix for RDMA_CM finalize rdma_destroy_id failure.
- Added Timeout env variable for RDMA_CM ARP.
- Fix for RDMA_CM invalid event in finalize.
- Fix for shmem memory collectives related memory leaks
- Updated src/mpi/romio/adio/ad_panfs/Makefile.in include path to find mpi.h.
- Fixed header caching error on handling datatype messages with small vector
sizes.
- Change the finalization protocol for UD connection manager.
- Fix for the "command line too long" problem.
- Change the CKPT handling to invalidate all unused registration cache.
- Added ofed 1.2 interface change patch for iwarp/rdma_cm
- Fix for rdma_cm_get_event err in finalize.
- Fix for when MV2_IBA_HCA is used.
