Compiling Fortran Codes with TAU• If your Fortran code uses free format in .f files (fixed is default for .f), you may use:% setenv TAU_OPTIONS ‘-optPdtF95Opts=“-R free” -optVerbose ’• To use the compiler based instrumentation instead of PDT (source-based):% setenv TAU_OPTIONS ‘-optCompInst -optVerbose’• If your Fortran code uses C preprocessor directives (#include, #ifdef, #endif):% setenv TAU_OPTIONS ‘-optPreProcess -optVerbose -optDetectMemoryLeaks’• To use an instrumentation specification file:% setenv TAU_OPTIONS ‘-optTauSelectFile=mycmd.tau -optVerbose -optPreProcess’% cat mycmd.tauBEGIN_INSTRUMENT_SECTIONmemory file=“foo.f90” routine=“#”# instruments all allocate/deallocate statements in all routines in foo.f90loops file=“*” routine=“#”io file=“abc.f90” routine=“FOO”END_INSTRUMENT_SECTION13 th DOE ACTS Workshop: Scalable and Robust Libraruesabd Tiiks fior High-End ComputingTAUhttp://tau.uoregon.edu
