All,
Basically I am asking for information on how to use hpx::find_locality. I
am trying to write a simple program that runs an action on a random
locality and then terminates. This seems to be simple but I am not getting
this code to work. This is a small program to test what I want:
#include <hpx/hpx_main.hpp>
#include <hpx/include/iostreams.hpp>
void sayhello(){
hpx::cout << "hello\n";
}
HPX_PLAIN_ACTION(sayhello,sayhello_action);
int main(){
hpx::async<sayhello_action>(hpx::find_locality(sayhello_action::get_component_type()));
return 0;
}
The previous code compiles however I get this error:
my_hpx_program: /usr/local/include/boost/smart_ptr/intrusive_ptr.hpp:193:
T& boost::intrusive_ptr<T>::operator*() const [with T =
hpx::naming::detail::id_type_impl]: Assertion `px != 0' failed.
This tells me that maybe I need to register or instantiate a component
implementing the plain action somewhere. However I cannot find any code,
documentation or reference to the use of hpx::find_locality .Changing to
hpx::find_here works normally which makes it more confusing to me.
Thanks.
