DataSpaces Releases:

In 2020, DataSpaces transitioned from the DART RPC and bulk transfer library to Mercury. This marked a transition to DataSpaces 2 (dspaces):

Development features (pending release - see master branch on GitHub repo:

  • Python bindings
  • Non-blocking version of dspaces_put()
  • Improved data subscription performance
  • Aries fabric support in dspaces
  • Improved scaling perfomance for dspaces_init()

2.1.x: Most recent release: March 2021

  • Add streaming metadata put/get interface
  • Add non-blocking data subscription with callbacks
  • Support building as a shared library
  • Add option to allocate data buffer inside dspaces_get()

2.0.x: Most recent release (candidate): November 2020 (should not be used for new development)

  • Replace DART RPC layer with Mercury
  • Add subscription-based reads (superecedes locking for most use cases)
  • Enable hybrid server/client processes
  • Add experimental asynchronous data draining with index relocation

Legacy DataSpaces 1.x Releases:

Development code can be found on the DataSpaces 1.x Github Repo (no longer in active development and deprecated)

1.8.x Most recent release: May 2019

  • Added new metadata support API calls (see header file for usage.)
  • Various bug fixes and performance improvements for InfiniBand transport.

1.7.x Most recent release: September 2018

  • Added lock type 3
  • Added DataSpaces-as-a-Service (DSaaS) functionality.
  • Added shared-memory based communication for collocated peers.
  • Various performance improvements and bug-fixes.
  • Deprecated and removed DCMF, Portals, and PAMI transport methods.

1.6.x Most recent release: June 2017

  • Added support for Cray Dynamic RDMA Credentials (DRC)
  • Supports Aries on Cray XC40 systems.
  • Necessary for NERSC’s Cori machine: use –enable-drc with configure
  • Improved support for IBM XL compiler
  • Added network support: Aries for Cray XC30.
  • Updated support for automake-1.12 and above.
  • Added network support: socket for TCP/IP.
  • Added feature: new data deleting API for removing data identified by version, from the staging area.
