Typedef Documentation

LdbId

typedef LDObjid LdbId

In the new 64-bit id case defining LdbId as CmiUInt8, the first 32 bits store the object's index and the second 32 bits store the type.

In the old int[4] id case defining LdbId as LDObjid, element 0 stores the object's index, element 1 stores the type, and elements 2 and 3 are unused.

Enumeration Type Documentation

anonymous enum

anonymous enum

Define the types encoded into the load balancing id. Use negative numbers because the nonbonded/self types are represented with the leading patch ID for that compute, when available.

Enumerator
NONBONDED_OR_SELF_TYPE	represents nonbonded or self compute
PATCH_TYPE	represents a patch
BONDED_TYPE	represents bonded compute
