Version 1.3.3

Backport to fix support for GCC >= 10

Version 1.5.1

Build/Installation

• Add small improvements to the macro config for checkign Infiniband device.
• Stop configuration if MPI is requested but not present.
• Fix ibverbs configuration problem.

Fixes

• Automatic selection of a working IB device.
• Set GASPI_MAX_NUMAS to 16 and return error in libGPI2.
• Delete only queues above a limit greater than eight in test.
• Fix clean up of queues in gaspi_proc_term.
• Allows larger count of devices (netdev_id) up to 4.
• Fix bug in queue verification macro.
• Remove constraint of having at least one queue.
• Add test to check error of waiting on a deleted queue.

Version 1.5.0

Functionality

• Add support for PowerPC architecture (ppc64).
• Add support for arm64 architecture.
• Add support for zero size messages.
• Remove timing and warning messages in gaspi_run.

API

• Move version numbering to own header which is made public (GPI2_VERSION.h)
• Remove gaspi_machine_type function and references

Build/Installation

• Remove source and build files of tests and microbenchmarks from installation.
• Update infiniband configuration macro
• Set -libverbs directly in the devices macro file.
• Fix problem(s) with the (installed) test binaries for lib*.so
• Add host cpu architecture to final configuration output.
• Look in /lib when user specificies a path for for the infiniband option.
• Fix GPI2.pc: add missing line.
• Fix build: use LIBS instead of LDFLAGS for libibverbs.

Fixes

• Fix locking in case of error of gaspi_queue_create.
• Hackfix: kill also binaries with lt-* prefix to allow proper interruption
• Fix tests that relied on the assumption that minimal communication is 1 byte.
• Fix batch/interactive jobs in slurm, make machinefile optional.
• Fix gaspi_set_config: only set user_net paramater if network has been changed.
• Init: check right at begin if already initialized.
• sn: use poll() instead of select() to wait for connections.

Documentation

• Update README:
  • Some documentation on how to use GPUdirectRDMA.
  • Usage of tests and microbenchmarks.
  • Information for shared libraries usage.
  • Update information on usage of Infiniband extensions.
• Add a script example for SGE.
• Improve Slurm submission script.

General clean-ups and minor refactorings.

Happy GPI-2 hacking!

Version 1.3.2

Backport to fix issue in install script

Version 1.3.1

Backport with fix to only set user_net if network has been changed.

Version 1.4.0

Functionality:

• SLURM support
• Auto-tools based build system
• Clean-up of GPU support
• Implement GASPI_QUEUE_FULL
• Implement gaspi_read_notify, gaspi_read_list_notify
• Support for connect-ib (atomics) with Infiniband extensions
• GASPI spec compliance
  • queue_depth -> queue_size_max
  • add gaspi_passive_transfer_size_min
  • gaspi_segment_create more spec-compliant: establish communication infrastructure (STATIC)
• Remove restricition of 255 elements for gaspi_allreduce operations
• Statistics for segment related functions
• configurability (gaspi_config_t):
  • elems in allreduce
  • device options:
    • tcp: port
    • ib: device, mtu, port check
  • sn persistent
  • sn timeout
• Add further tests, remove some redundant ones

Fixes:

• Fix maximum transfer size issues

• Fix issues on large-scale

• Fix timeout on topology broadcast

• SN: exponential backoff delay

• SN: simplify events handling

• SN: use an allgather for collective operations (e.g. gaspi_segment_create)

• TCP shutdown and clean-up

• Memory and resources leaks

• Other small fixes

• Several refactorings for less duplication and better readability.

Happy GPI-2 hacking!
