Please use the compiler wrappers to compile for the compute nodes.
compiler wrapper
On HazelHen compiler wrappers should be used to compile your application for the compute nodes.
| wrapper | language |
|---|---|
| ftn | FORTRAN |
| cc | C |
| CC | C++ |
Thus if you want to compile your application , e.g. including MPI, you just:
$> ftn hello.f90 -o my.exe
change options
The actual compiler used depend on the selected programming environment (cray/intel/gnu/pgi), which can be switched using e.g.:
$> module switch PrgEnv-cray PrgEnv-gnu
(Please review also the information about the module environment). The advantage of the module environment is that the modules automatically add the related compiler and linker flags the compile/link line. Thus you do not have to take care about these. For example, if you want to use FFTW, just load the module:
$> module load fftw
and recompile without additional options for this:
$> ftn myAppWithFFTW.f90 -o my.exe
You can see all the used compile and link options using the wrapper option -craype-verbose
$> ftn -craype-verbose myAppWithFFTW.f90 -o my.exe ftn_driver.exe -hcpu=haswell -hstatic -D__CRAYXC -D__CRAY_HASWELL -D__CRAYXT_COMPUTE_LINUX_TARGET -hnetwork=aries hello.f90 -Wl,-rpath=/opt/cray/cce/8.5.1/craylibs/x86-64 -ulast_user_arg -I /opt/cray/cce/8.5.1/craylibs/x86-64/include -I/usr/include -L/opt/cray/cce/8.5.1/CC/x86-64/lib/x86-64 -Wl,-rpath=/opt/cray/cce/8.5.1/CC/x86-64/lib/x86-64 -L/opt/gcc/4.8.1/snos/lib64 -Wl,-rpath=/opt/cray/gcc-libs -L/usr/lib64 -Wl,-rpath=/usr/lib64 -L/lib64 -Wl,-rpath=/lib64 -ugcc_base=/opt/gcc/4.8.1/snos -uno_driver_libs -Wl,/opt/cray/cce/8.5.1/craylibs/x86-64/libmodules.a,/opt/cray/cce/8.5.1/craylibs/x86-64/libomp.a,/opt/cray/cce/8.5.1/craylibs/x86-64/libopenacc.a, -I/opt/cray/fftw/3.3.4.9/haswell/include -I/opt/cray/mpt/7.4.1/gni/mpich-cray/8.3/include -I/opt/cray/libsci/16.07.1/CRAY/8.3/x86_64/include -I/opt/cray/rca/1.0.0-2.0502.60530.1.62.ari/include -I/opt/cray/alps/5.2.4-2.0502.9774.31.11.ari/include -I/opt/cray/xpmem/0.1-2.0502.64982.5.3.ari/include -I/opt/cray/gni-headers/4.0-1.0502.10859.7.8.ari/include -I/opt/cray/dmapp/7.0.1-1.0502.11080.8.76.ari/include -I/opt/cray/pmi/5.0.10-1.0000.11050.0.0.ari/include -I/opt/cray/ugni/6.0-1.0502.10863.8.29.ari/include -I/opt/cray/udreg/2.3.2-1.0502.10518.2.17.ari/include -I/opt/cray/cce/8.5.1/craylibs/x86-64/pkgconfig/../include -I/opt/cray/cce/8.5.1/craylibs/x86-64/pkgconfig/..//include -I/opt/cray/wlm_detect/1.0-1.0502.64649.2.1.ari/include -I/opt/cray/krca/1.0.0-2.0502.63139.4.31.ari/include -I/opt/cray-hss-devel/7.2.0/include -L/opt/cray/fftw/3.3.4.9/haswell/lib -L/opt/cray/dmapp/default/lib64 -L/opt/cray/mpt/7.4.1/gni/mpich-cray/8.3/lib -L/opt/cray/dmapp/default/lib64 -L/opt/cray/mpt/7.4.1/gni/mpich-cray/8.3/lib -L/opt/cray/libsci/16.07.1/CRAY/8.3/x86_64/lib -L/opt/cray/rca/1.0.0-2.0502.60530.1.62.ari/lib64 -L/opt/cray/alps/5.2.4-2.0502.9774.31.11.ari/lib64 -L/opt/cray/xpmem/0.1-2.0502.64982.5.3.ari/lib64 -L/opt/cray/dmapp/7.0.1-1.0502.11080.8.76.ari/lib64 -L/opt/cray/pmi/5.0.10-1.0000.11050.0.0.ari/lib64 -L/opt/cray/ugni/6.0-1.0502.10863.8.29.ari/lib64 -L/opt/cray/udreg/2.3.2-1.0502.10518.2.17.ari/lib64 -L/opt/cray/atp/2.0.2/libApp -L/opt/cray/cce/8.5.1/craylibs/x86-64/pkgconfig/../ -L/opt/cray/wlm_detect/1.0-1.0502.64649.2.1.ari/lib64 -Wl,-Ttext-segment=0x20000000,-zmax-page-size=0x20000000 -Wl,--whole-archive,-lhugetlbfs,--no-whole-archive -Wl,--no-as-needed,-lAtpSigHandler,-lAtpSigHCommData -Wl,--undefined=_ATP_Data_Globals -Wl,--undefined=__atpHandlerInstall -lpthread -lfftw3f_mpi -lfftw3f_threads -lfftw3f -lfftw3_mpi -lfftw3_threads -lfftw3 -lmpichf90_cray -lrt -lpthread -lugni -lpmi -lsci_cray_mpi_mp -lm -lf -lsci_cray_mp -lmpich_cray -lrt -lpthread -lugni -lpmi -lsci_cray_mp -lcraymp -lm -lpthread -lf -lpgas-dmapp -lfi -lu -lrt -Wl,--undefined=dmapp_get_flag_nbi -ldmapp -lugni -ludreg -lpthread -lm -lcray-c++-rts -lcraystdc++ -lxpmem -ldmapp -lpthread -lpmi -lpthread -lalpslli -lpthread -lwlm_detect -lugni -lpthread -lalpsutil -lpthread -lrca -ludreg -lquadmath -lm -lomp -lcraymp -lpthread -lrt -ldl -lcray-c++-rts -lcraystdc++ -lm -lmodules -lm -lfi -lm -lquadmath -lcraymath -lm -lgfortran -lquadmath -lf -lm -lpthread -lu -lrt -ldl -lcray-c++-rts -lcraystdc++ -lm -lcsup -Wl,--as-needed,-latomic,--no-as-needed -Wl,--as-needed,-lgfortran,--no-as-needed -Wl,--whole-archive,-ltcmalloc_minimal,--no-whole-archive -lstdc++ -lpthread -Wl,--start-group,-lc,-lcsup,-lgcc_eh,-lm,-lgcc,--end-group -Wl,-T/opt/cray/cce/8.5.1/craylibs/x86-64/2.23.1.cce.ld
link type
On HazelHen the default link type is static, on the login nodes as well as on the mom/compute nodes. You can specify the link type using the -dynamic or -static compiler/linker option, e.g.:
ftn -dynamic mysrc.f90 -o myapp.exe
OR set the environment variable, e.g.:
CRAYPE_LINK_TYPE=dynamic
documentation
Nevertheless, if you want to fine tune your applications, there a lot of compiler options you could try, like inlining, vectorization, etc. You find all these compiler options in the related man page, e.g.:
$> man crayftn
The compilers for the different PrgEnv are:
| PrgEnv | Description | compiler |
|---|---|---|
| PrgEnv-cray | Cray Compilation Environment | crayftn, craycc, crayCC |
| PrgEnv-intel | Intel Composer Suite | ifort, icc, icpc |
| PrgEnv-gnu | GNU Compiler Collection | gfortran, gcc, g++ |
| PrgEnv-pgi | Portland Group Compilers | pgf90, pgcc, pgCC |
