Dear,
I managed to use directives OpenMP in R.
To compile I used the gfortran directly. For example:
gfortran-shared-O2 teste.f90-fopenmp-fPIC
By using the code in R, it works perfectly!
However, I need to use some specific libraries of R, for use in C functions in
Fortran 95.
When compiling using the command:
gfortran-shared-O2-o teste.f90 myrandom.c func.out -fopenmp -fPIC
However, I need to indicate the path for the compiler to use the files of the
type: Rmath.h, R.h and others.
I observed the project ROMP and the library Rcsdp. The developers of the
library Rcsdp in the installation file present the following modification in
the compiler for enable the OpenMP.
CFLAGS=CFLAGS=-O3 -march=nocona -m64 -fprefetch-loop-arrays -ftree-vectorize
-ftree-vectorizer-verbose=1 -fopenmp -ansi -Wall -DNOSHORTS -DBIT64
-DUSEOPENMP -I../include
LIBS=LIBS=-static -L../lib -lsdp -llapack -lptf77blas -lptcblas -latlas -lgomp
-lrt -lpthread -lgfortran -lm
I already tried
~/Fortran/parallel/tri $ export PKG_FCFLAGS= -fopenmp
bash: export: `-fopenmp': not a valid identifier
I could indicate the path of the files R.h, Rmath.h and other to the gfortran?
How?
Thank you!
