two questions for the stellar community - if i'm writing a distributed
program that does not use the hpx spmd model, does hpx require the
partitioned_vector storing components to be registered into the agas? if
so, does hpx also require a call the connect function? several of the
non-spmd partitioned_vector unit tests do not require register/connect -
were those unit tests intended only to support single-node testing or is
distributed execution also supported?
on a separate issue, i'd like to access the contents of a distributed
vector that stores a component called 'dataset_t' (the component inherits
from hpx::components::simple_component_base<dataset_t> ; the client
interface for the component inherits from
hpx::components::client_base<dataset_t, server::dataset_t>).
currently, the following code compiles and produces a runtime exception.
std::vector<std::size_t> pos = { static_cast<std::size_t>(idx) };
std::vector<dataset_t> svec = dataset_arr.get_values_sync(pos);
hpx::future<void> fc = svec[0].create(args);
fc.wait();
hpx::future<void> fv = dataset_arr.set_values(pos, svec);
fv.wait();
the program runs on 1 node/host without any runtime arguments applied. the
runtime exception reads:
"{what}: this client_base has no valid shared state: HPX(no_state)"
how should i comprehend this runtime exception?
also, when the following, much simpler implementation, of sample code runs:
hpx::future<dataset_t> fd =
dataset_arr.get_value(static_cast<std::size_t>(idx));
fd.wait();
i had the following compile error:
"hpx/traits/get_remote_result.hpp:25:41: error: no matching function for
call to
'hpx::naming::id_type::id_type(std::remove_reference<dataset_t&>::type"
any help, questions, or assistance would be appreciated!
