Age	Commit message (Collapse)	Author
2020-03-21	2.6.4-1	Sylvain Jeaugey
	Add support for network collectives. Add support for XML topology dump/injection. Add text values for GDR and P2P Levels, including "NVL". Add speed detection for PCI, Infiniband and Ethernet cards. Add CPU detection for ARM and AMD CPUs. Add support for adaptive routing on Infiniband. Change NET plugin API to v3 : merge PCI path and GPU pointer capability into a single structure and add other properties.
2020-02-12	Fix Allgather operations above 4G with multiple GPUs per process.	Sylvain Jeaugey
	Fixes nccl-tests#37. Direct offsets were still on 32 bits in the low-level primitives.
2019-11-20	2.5.6-1 (#255)	Sylvain Jeaugey
	Add LL128 Protocol. Rewrite the topology detection and tree/ring creation (#179). Improve tree performance by sending/receiving from different GPUs. Add model-based tuning to switch between the different algorithms and protocols. Rework P2P/SHM detection in containers (#155, #248). Detect duplicated devices and return an error (#231). Add tuning for GCP
2019-04-05	NCCL 2.4.6-1	David Addison
	Added detection of IBM/Power NVLink bridge device. Add NUMA support to PCI distance calculations. Added NCCL_IGNORE_CPU_AFFINITY env var. Fix memory leaks; GithubIssue#180 Compiler warning fix; GithubIssue#178 Replace non-standard variable length arrays. GithubIssue#171 Fix Tree+Shared Memory crash. GithubPR#185 Fix LL cleanup hang during long running DL jobs. Fix NCCL_RINGS environment variable handling. Added extra checks to catch repeat calls to ncclCommDestroy() GithubIssue#191 Improve bootstrap socket connection reliability at scale. Fix hostname hashing issue. GithubIssue#187 Code cleanup to rename all non device files from .cu to .cc
2019-01-30	2.4.2-1	Sylvain Jeaugey
	Add tree algorithms for allreduce to improve performance at scale. Add ncclCommAbort() and ncclCommGetAsyncError() to properly handle network errors and be permit recover. Detect initial CPU affinity and no longer escape it.
2018-12-14	Qualify nullptr_t with std::	Christian Sigg

2018-12-14	Two temporary workarounds for cuda-clang issues.	Christian Sigg

2018-11-27	Add support for external network.	Sylvain Jeaugey
	Dynamically load external network from libnccl-net.so. Add init function in networks. Move PCI scoring to net.cu, only ask transport to provide a path. Simplify CUDA PCI path detection. Add dummy external network
2018-11-10	Generate nccl.h in build instead of src	Sylvain Jeaugey
	Generating nccl.h in src makes source directories dirty after builds.
2018-10-25	2.3.7-1v2.3.7-1	David Addison
	Improved LL tuning for multi-node jobs. Improved bootstrap for large job scaling. Fixed a hang during bootstrap due to socket reuse. Added operation name to the COLL INFO logging.
2018-09-26	2.3.5-5v2.3.5-5	Sylvain Jeaugey
	Add support for inter-node communication using sockets and InfiniBand/RoCE. Improve latency. Add support for aggregation. Improve LL/regular tuning. Remove tests as those are now at github.com/nvidia/nccl-tests .
