7.40. cudaLaunchMemSyncDomainMap Struct Reference

[Data types used by CUDA Runtime]

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.

Public Variables

unsigned char  default_
unsigned char  remote


unsigned char cudaLaunchMemSyncDomainMap::default_ [inherited]

The default domain ID to use for designated kernels

unsigned char cudaLaunchMemSyncDomainMap::remote [inherited]

The remote domain ID to use for designated kernels
