DISTRIBUTED module

Description

Module that enables distributed parallel computation in Chrono.

This module implements MPI parallel computing algorithms that can be used as a faster alternative to the default simulation algorithms in Chrono::Engine. This module depends on the Chrono::Parallel module.

Enumeration Type Documentation

COMM_STATUS

enum chrono::distributed::COMM_STATUS

Location and status of a given body with respect to this rank.

Enumerator
OWNED	None, empty, disabled.
GHOST_UP	exclusive to this rank
GHOST_DOWN	a proxy for a body on high neighbor rank
SHARED_UP	a proxy for a body on low neighbor rank
SHARED_DOWN	has a proxy body on high neighbor rank
UNOWNED_UP	has a proxy body on low neighbor rank
UNOWNED_DOWN	unrelated to this rank
GLOBAL	unrelated to this rank
UNDEFINED	Present on all ranks.

MESSAGE_TYPE

enum chrono::distributed::MESSAGE_TYPE

Types of internal message that can be sent.

Enumerator
UPDATE	Introduction of new body to a rank.
FINAL_UPDATE_GIVE	Update for an existing body on a rank from the owning rank.
FINAL_UPDATE_TAKE	Update which ends in the other rank taking exclusive ownership.
UPDATE_TRANSFER_SHARE	Update which ends in this rank taking exclusive ownership. Update which updates the primary rank for the body
