Detailed Description

Attach launchers are used for attaching existing physical resources outside of a Legion application to a specific logical region. This can include attaching files or arrays from inter-operating programs. We provide a generic attach launcher than can handle all kinds of attachments. Each attach launcher should be used for attaching only one kind of resource. Resources are described using Realm::ExternalInstanceResource descriptors (interface can be found in realm/instance.h). There are many different kinds of external instance resource descriptors including:

Realm::ExternalMemoryResource for host pointers (realm/instance.h)
Realm::ExternalFileResource for POSIX files (realm/instance.h)
Realm::ExternalCudaMemoryResource for CUDA pointers (realm/cuda/cuda_access.h)
Realm::ExternalHipMemoryResource for HIP pointers (realm/hip/hip_access.h)
Realm::ExternalHDF5Resource for HDF5 files (realm/hdf5/hdf5_access.h) ... Please explore the Realm code base for all the different kinds of external resources that you can attach to logical regions.
