openmp not working
but if I use cling, it’s OK below
cling -I/usr/local/include -fopenmp -llibomp test.cpp
how could I use openmp with rootcling?
I guess you don’t mean
rootcling, the dictionary generator:
You mean how you can run that code with ROOT’s interpreter? Can you convert it in a macro and run it as explained here?
I guess you need to also set the path in which the library is:
yes, my mistake, what I meant is that
could I use openmp at root interpreter
openmp not working with result 0123456789
It seem it use only one core. not parallel
I don’t see why it should not create your threads, what happens if you compile the same program instead of running it via the ROOT interpreter?
If I compile it, it’s OK for parallel
@Axel any idea why the openmp code is serialized when executed via the interpreter, as opposed to compiled?
