CRAY XC40 compiler wrapper
Please use the compiler wrappers to compile for the compute nodes.
compiler wrapper
On HazelHen different compilers are available for different languages and different vendors. For all the different compilers please use compiler wrappers 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
On HazelHen compilers from CRAY, GNU, INTEL and PGI are available. 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,--whoUntitled 1le-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
Building software for the front end nodes
By default the environment compiles and links software for the compute node architecture. To build software for the front end nodes the CPU architecture has to be changed with
$> module sw craype-haswell craype-sandybridge
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 CoUntitled 1mposer Suite | ifort, icc, icpc |
PrgEnv-gnu | GNU Compiler Collection | gfortran, gcc, g++ |
PrgEnv-pgi | Portland Group Compilers | pgf90, pgcc, pgCC |
