assertion failure in persona.hpp

[Nenad Vukicevic]

After the switch to develop branch and update yesterday I am having an assertion error on one of the tests:

upcxx/persona.hpp:222

Happens on the exit, and as far as know I do not run any code that is persona specific. And it happiness on only one of them (out of 10).

[Dan Bonachea]

Nenad, can you attach the test that is showing the problem?

[Nenad Vukicevic]

It is regular guppie test. Will attach.

[Nenad Vukicevic]

I compile it like

$(CXX) guppie.cpp get_time.c $(PPFLAGS) $(LDFLAGS) $(LIBFLAGS) -Wno-inline -o guppie

and take default for running.

[Dan Bonachea]

For the record, this appears to be a very naive and low-fidelity implementation of guppie for UPC++ and should not in any way be considered a "good" example of how to best express the crucial update_table function in UPC++ (even in the context of a fine-grained version that does not aggregate communication). There are many obvious improvements that should be made to leverage UPC++'s asynchrony features as intended, before this could ever be said to accurately represent a good UPC++ implementation.

However the only obvious mistake I see is that main() fails to upcxx::finalize before exit, which might explain the assertion failure.

I also have the gappie-async version that does not fail like this. Will give it a try.

[Nenad Vukicevic]

I added finalize() and there are no assertion any more.
