[libfabric-users] address size

[Biddiscombe, John A.]

when using native address formats, I have the following hardcoded into my stuff


#ifdef HAVE_LIBFABRIC_GNI
#define HAVE_LIBFABRIC_LOCALITY_SIZE 48
#endif

#ifdef HAVE_LIBFABRIC_CXI
#define HAVE_LIBFABRIC_LOCALITY_SIZE 4
#endif

#if defined(HAVE_LIBFABRIC_VERBS) || defined(HAVE_LIBFABRIC_TCP) ||                                \
    defined(HAVE_LIBFABRIC_SOCKETS) || defined(HAVE_LIBFABRIC_PSM2)
#define HAVE_LIBFABRIC_LOCALITY_SIZE 16
#define HAVE_LIBFABRIC_LOCALITY_SOCKADDR
#endif


I want to use amazon EFA, and have no idea how large an address struct is with FI_ADDR_EFA

What is the correct way to find this info so that addresses can be safely copied around when compiling against different providers?


Thanks


JB
