- Update openucx-s390x-support.patch to fix support of 1.5.0 on s390x (bsc#1121267)
- Add baselibs.conf for ppc
2019-02-22 - Martin Li?ka <>
- Update to v1.5.0 (bsc#1121267)
* Features:
* New emulation mode enabling full UCX functionality (Atomic, Put, Get)
* over TCP and RDMA-CORE interconnects which don't implement full RDMA semantics
* Non-blocking API for all one-sided operations. All blocking communication APIs marked
* as deprecated
* New client/server connection establishment API, which allows connected handover between workers
* Support for rdma-core direct-verbs (DEVX) and DC with mlx5 transports
* GPU - Support for stream API and receive side pipelining
* Malloc hooks using binary instrumentation instead of symbol override
* Statistics for UCT tag API
* GPU-to-Infiniband HCA affinity support based on locality/distance (PCIe)
* Bugfixes:
* Fix overflow in RC/DC flush operations
* Update description in SPEC file and README
* Fix RoCE source port for dc_mlx5 flow control
* Improve ucx_info help message
* Fix segfault in UCP, due to int truncation in count_one_bits()
* Multiple other bugfixes (full list on github)
* Tested configurations:
* InfiniBand: MLNX_OFED 4.4-4.5, distribution inbox drivers, rdma-core
* CUDA: gdrcopy 1.2, cuda 9.1.85
* XPMEM: 2.6.2
* KNEM: 1.1.2
2018-11-06 -
- Update to v1.4.0 (bsc#1103494)
* Features:
* Improved support for installation with latest ROCm
* Improved support for latest rdma-core
* Added support for CUDA IPC for intra-node GPU, CUDA memory
allocation cache for mem-type detection, latest Mellanox
devices, Nvidia GPU managed memory, multiple connections
between the same pair of workers, large worker address for
client/server connection establishment and INADDR_ANY, and
for bitwise atomics operations.
* Bugfixes:
* Performance fixes for rendezvous protocol
* Memory hook fixes
* Clang support fixes
* Self tl multi-rail fix
* Thread safety fixes in IB/RDMA transport
* Compilation fixes with upstream rdma-core
* Multiple minor bugfixes (full list on github)
* Segfault fix for a code generated by armclang compiler
* UCP memory-domain index fix for zero-copy active messages
