hello,
first of all thank you for replying so fast.
@Hartmut, i believe that all of my futures are
shared_future<void>
where do i define it int?
@Thomas, i tried to define
hpx::lcos::shared_future<void> do_work(*const* unsigned int color, *const*
std::vector<hpx::lcos::shared_future<void> >& dependencies)
(adding the const), but i still get the same error
what i ultimately would like to achieve is to perform in parallel a
triangular solve.
for now the code i am trying to write is much simpler than that:
i have 6 colors (identified as unsigned ints)
numbered as 0 1 2 3 4 5
i write as a helper for myself a dependency list
dependencies[0]; //first has no dependencies
dependencies[1].insert({0});
dependencies[2].insert({0,1});
dependencies[3].insert({0,2});
dependencies[4].insert({1});
dependencies[5].insert({0});
this tells that 1 depends on 0
2 depends on 0 and 1
3 depends on 0 and 2
4 depends on 1
5 depends on 0
what i (try) to do next is to define a
shared_future for the color 0, which depends on nothing, so that it can be
executed straight away
then a future for color 1, which depends on 0
and so forth.
for this i allocate the shared_futures in a map so that when i define
the do_work for color 2 i can recover the shared_future i constructed for 0
and 1
all the code compiles fine (on gcc5.4, with the compiler flags listed)
except for
the line in which i call the dataflow.
btw, my shared_futures should actually contain/return nothing so i defined
them as "void" i wouldn't mind defining them as int and passing them the
color they represent
regards
Riccardo
