Expand description

Memory Synchronization Domain map

See ::cudaLaunchMemSyncDomain.

By default, kernels are launched in domain 0. Kernel launched with ::cudaLaunchMemSyncDomainRemote will have a different domain ID. User may also alter the domain ID with ::cudaLaunchMemSyncDomainMap for a specific stream / graph node / kernel launch. See ::cudaLaunchAttributeMemSyncDomainMap.

Domain ID range is available through ::cudaDevAttrMemSyncDomainCount.
