<jaafar> Suppose there is a relationship between two tasks such that one must be complete before the other begins
<jaafar> Is there an abstraction in HPX that has these semantics directly?
<jaafar> I was thinking about the scan algorithms (as usual) and futures are used there for this purpose, I believe
<jaafar> future<void>
<jaafar> I guess it makes sense but there is no data transferred there
<jaafar> Correction: future<Result> but for the purpose of sequencing the value is not used

<simbergm> jbjnr: is the ibverbs parcelport actually still functional? does it need to be kept around?

<heller> simbergm: I was hoping it got superseeded by the libfabric one, but I might be wrong

<simbergm> heller: I was hoping so too... now would be a good time to deprecate or remove it
<heller> simbergm: from the 1.4.0 release or after it?
<heller> simbergm: I'd say: deprecate it for 1.4.0 remove it afterwards, fix it for 1.5 ;)
<simbergm> well, at least deprecating in 1.4.0, but if noone is using it we might even get away with removing it
<simbergm> heller: exactly
<heller> I'd suspect that noone is really using it
<simbergm> "fix it"?
<heller> fix libfabric if there are problems with it when using ibverbs as the underlying provider
<heller> however, it doesn't hurt to keep it around for this release, does it?
<simbergm> no, not at all
<simbergm> I'll just deprecate it
<simbergm> doesn't even have to be removed in the next release if it turns out someone is relying on it
<heller> well, if the libfabric parcelport is stable, there shouldn't be an issue to upgrade
<heller> IMHO
<heller> we just have to state in the release notes
