Modules

backend

RDMA backend implementations.

config

RDMA configuration attributes.

device_selection

PCI topology parsing and device discovery utilities for RDMA device selection.

efa

EFA (Elastic Fabric Adapter) specific RDMA operations.

local_memory

Local memory abstractions for RDMA operations.

Macros

cu_check

register_ibv_device_impl

Submits an inventory entry for a concrete IbvDeviceImpl.

Structs

EnsureRdmaManager

Caller -> owner request to ensure a proc mesh’s per-proc managers are ready.

EntryId

Owner-local handle for a ProcMeshRef.

GetTcpActorRef

Serializable query for resolving the TcpManagerActor ref from a remote RdmaManagerActor.

RdmaAction

A batch of RDMA operations submitted as a single unit.

RdmaManagerActor

RdmaManagerOwnerActor

RdmaManagerReady

Owner -> manager-mesh readiness cast, delivered to every per-proc RdmaManagerActor. Carries the owner ref so each rank can post ReadyAck back after its own init() (RMR-1).

RdmaOp

A single RDMA operation to be submitted to a backend.

RdmaRemoteBuffer

Lightweight handle representing a registered RDMA buffer.

ReadyAck

Per-proc manager -> owner readiness acknowledgement, one per rank.

ReleaseBuffer

Serializable release message for wire transport.

Enums

RdmaInitError

A typed initialization failure returned by the RDMA manager owner.

RdmaManagerMessage

Local-only messages for the RdmaManagerActor.

RdmaOpType

Type of RDMA operation.

RdmaTransportLevel

Transport level, ordered slowest to fastest.

Constants

RDMA_MANAGER_OWNER_ACTOR_NAME

Static client-root service name for the RDMA manager owner.
