1.1.3

New features

  • IPUoF client: Add get_contiguous_remote_buffer() to decrease host memory usage.

    This allows remote buffers to exist only on the IPU-Machine, reducing the memory footprint on the host.

    Poplar will make use of this feature where it can.

  • Fixed data-integrity check for gc-iputraffictest --all-links where one IPU wasn’t correctly checked in certain cases.

Bug Fixes

  • Capture correct clock speed on Bow machines.

  • IPUoF: Add serverHost to error message when failing to interact with V-IPU server.

  • NLC error count totals are accumulated only when the link is up.

Other improvements

  • IPUoF client: Add destination IP address to all client log messages.

  • Each IPU issues a detach mailbox command. This is to support power-saving modes on Bow-2000 systems.

  • Remove the IPUResource::writeTileMemory public function.

  • Remove functions from GCDA that assume a default IPU.
