Anyone knows how to get the current host name from a Cray Fortran program? I want basically the output of UNIX gethostname(). After scouring Craydocs pages, I see that the PXF* functions do not seem to contain this information.

Cray Fortran is quite ahead in modern Fortran features. You can call the
gethostname()using C interoperability features of Fortran 2003. The name would be null terminated. You can also probably useGET_ENVIRONMENT_VARIABLEintrinsic subroutine from Fortran 2003.Try using PXFGETENV to get the value of the
HOSTNAMEenvironment variable.Since all Cray machines have MPI, you can use MPI_Get_processor_name from any dialect of Fortran.
