<zao> heller: I'm still messing around with the topology for degenerate machines. For N PUs, would it make more sense from a HPX perspective to have N fake cores with one PU each, or 1 fake core with N PUs? There is no information about hyperthreads anywhere, it's just a flat bunch of PUs, one per hardware thread.
<zao> Both ways will be a bit silly, just looking for the one that will make HPX algos suck less.
<zao> Leaning toward N single-PU cores.
<K-ballo> toss a coin
<K-ballo> where's hkaiser these days?
<jbjnr__> I was wondering the same
<jbjnr__> zao: N single PU cores would be the place to start
<zao> Punching the partitioner now, that ends up with empty pools.
<zao> Thus far I've found out that the remote GDB functionality of both VC++, VS Code and Qt Creator doesn't work :D
<zao> Also, I can't for the life of me get logging working.

<zao> New and exciting failures... "mmap() failed to allocate thread stack" and "assertion 'mode_ & mode_allow_oversubscription || num_threads == cfg_.num_threads_' failed: HPX(assertion_failure)"
<zao> Guessing I'm inconsistent somewhere, there's so many friendly helper functions in topology :)

<jbjnr__> zao: I get those mmap stack failed errors no some of the benchmarks
<jbjnr__> ^no = on
<zao> It would help if I had a proper development environment and not a GDB that crashes on accessing our thread_specific_ptr:s :D
