WebUCX is a middleware communication framework that relies on device drivers, e.g. RDMA, CUDA, ROCM. RDMA and OS-bypass network devices typically implement device drivers using the RDMA-core Linux subsystem that is supported by UCX. Support for other network abstractions can be added based on requests and contributions from the community. importance of being understandableWebConventional RDMA •RDMA traditionally used in Infinibandclusters. –A different network protocol supporting high bandwidth. •Infinibandlinks use credit-based flow control. –Losses are rare. •Transport layer in RDMA NICs not designed to deal with losses efficiently. –Receiver discards out-of-order packets. importance of being timelyWebRdma cgroup maintains resource accounting per cgroup, per device using resource pool structure. Each such resource pool is limited up to 64 resources in given resource pool by rdma cgroup, which can be extended later if required. This resource pool object is linked to the cgroup css.
