R + OpenMP
October 21, 2009
The following patch is corresponding to ROMP‘s Google code web site file:
16c16 `type` function `name`(`arg.str`) 48c48 `type` function `name`(`arg.str`) 78c78 function `name`() 99c99 integer function ifelse(cond,x,y) 132c132 # system("gfortran -dynamiclib -O3 main.f90 -o main.so") 134c134 system("gfortran -fopenmp -lpthread -shared -O3 main.f90 -o main.so -fPIC") 157c157 NTHREADS=2
The result is amazing:
