Hi All,
I have a PETSc application that need additional compiling flags to build
Hybrid MPI-OpenMP parallel application on WestGrid Supercomputer
(Canada) system.
The code and makefile work fine on my local machine for both Windows and
Linux, but when compiled on WestGrid Orcinus System for the OpenMP
version and Hybrid version, the OpenMP parallel part does not take
effect while only MPI parallel part takes effect. There is no error
while compiling the code. I am not sure if there is something wrong with
the makefile or something other setting.
The compiler flags need to build Hybrid MPI-OpenMP version on WestGrid
Orcinus is "-shared-intel -openmp -O2 -xSSSE3 -axSSE4.2,SSE4.1 -ip" .
For the sequential version or MPI parallel version, these flags are not
needed.
Would anybody help to check if the compiler flag (red) in the makefile
is correct?
Thanks,
Danyang
The makefile is shown below
include ${PETSC_DIR}/conf/variables
include ${PETSC_DIR}/conf/rules
#FC = ifort
SRC =./../
# Additional flags that may be required by the compiler ...
# This is required for the OpenMP parallel version and Hybrid MPI-OpenMP
parallel version
# not necessary for the sequential version and MPI version
DFCFLAG = -shared-intel -openmp -O2 -xSSSE3 -axSSE4.2,SSE4.1 -ip
#Flag for WestGrid Orcinus System
#Load PETSc module before make
#module load /global/system/Modules/modulefiles/intel-2011/petsc
FPPFLAGS = -DLINUX -DRELEASE -DPETSC -DMPI -DOPENMP
