13:45 <heller_> is hpx::util::unwrap not waiting on the futures to finish anymore?

13:46 <heller_> stupid me again

13:46 <jbjnr_> ?

15:03 aserio has quit [Ping timeout: 276 seconds]

15:05 <jbjnr_> whynot have an unwrap that internally uses a dataflow and then calls get to pass unwrapped - but ready - futures?

15:12 <K-ballo> that's what it used to do, sort of

15:13 <heller_> unwrap is supposed to 'strip' of the futures from the type you pass into

15:14 <heller_> object even

15:14 <heller_> there's no other way then to call get, is there?

15:56 <simbergm> jbjnr_: sorry if this is a stupid question but: do you have the do_background_work flag enabled for cholesky? if yes, what for?

15:56 <simbergm> (just looking at a version of hpx_mpi_linalg where it is enabled)

16:16 <github> hpx/fixing_3182 d6fa451 Hartmut Kaiser: Fixing return type calculation for bulk_then_execute....

16:17 <jbjnr_> simbergm: I do have it enabled, but I should not need it - I was thinking the other day that I should only allow background work on the MPI pool - but when I use just one process - then the mpi pool isn't created, so I'd end up wasting a CPU if I used it

16:17 <hkaiser> simbergm: I think we can remove background work completely if HPX_HAVE_NETWORKING=OFF

16:18 <jbjnr_> hkaiser: really? I thought there was some agas crap going on that needed it

16:18 <hkaiser> no agas crap needed if no networking is present

16:18 <hkaiser> all garbage collection is 100% local

16:18 <jbjnr_> it doesn't use a lot of CPU overall in my APEX summaries, but it probably causes some cache hit/miss diffs

16:19 <jbjnr_> if I disbale it, and things go wrong-what is mort likely to cause lock-ups etc

16:19 <jbjnr_> terminated thread clean-up? is that done in background work, or only during normal schedulng lopp

16:21 <jbjnr_> I'll try disabling it and see if anything breaks.

17:35 <victor_ludorum> Here https://github.com/STEllAR-GROUP/hpx/blob/master/src/runtime.cpp#L457 also "median value"
