MPI_VERSION :: VersionNumber
The supported version of the MPI standard.
MPI_LIBRARY :: String
The current MPI implementation: this is determined by
MPI_LIBRARY_VERSION :: VersionNumber
The version of the MPI library
MPI_LIBRARY_VERSION_STRING :: String
The full version string provided by the library
Check if the MPI implementation is known to have CUDA support. Currently only Open MPI provides a mechanism to check, so it will return
false with other implementations (unless overriden).
This can be overriden by setting the
JULIA_MPI_HAS_CUDA environment variable to
impl, version = identify_implementation()
Attempt to identify the MPI implementation based on
MPI_LIBRARY_VERSION_STRING. Returns a triple of values:
Stringwith the name of the MPI implementation, or
"unknown"if it cannot be determined,
VersionNumberof the library, or
nothingif it cannot be determined.
