<github> hpx/fixing_2699 dce77a9 Hartmut Kaiser: Fixed remove*, replace, reverse, search, and transform algorithms
<ajaivgeorge_> I am fixing the issues with the PR now, transform with tagged_tuple gives some errors. Also, I will put find, find_if, find_if_not in one PR and the other two in a different one.

<hkaiser> ajaivgeorge_: I'm not sure about the tagged_tuple comments ;)
<hkaiser> ajaivgeorge_: pls take everything with a grain of salt, I may always be wrong

<github> hpx/fixing_2699 6485c8c Hartmut Kaiser: Fixing transform_*_scan, and transform_reduce algorithms
<ajaivgeorge_> hkaiser: You are right, I had changed the return type from tagged_tuple to tuple while trying to fix errors which were actually fixed by adding the result type casting helpers in dispatch. Forgot to change back.
<hkaiser> ajaivgeorge_: FWIW, I wanted to thanks you for your work, very impressive!
<ajaivgeorge_> thank you. :)
<hkaiser> ajaivgeorge_: I hope you're having some fun ;)
<ajaivgeorge_> Yep, lots of fun. Thanks to mcopik, i can now dig through verbose template errors. :D

<hkaiser> heh
<zao> The key is squinting really hard.
vamatya has joined #ste||ar
<mcopik> ajaivgeorge_: btw, the build failed at one example
<ajaivgeorge_> mcopik: I had forward declared for_each at the beginning of the file so that it can be used in for_each_n.
<ajaivgeorge_> Which is why later proj is not default paramtered again later, this error seems to be related to that.
Vir has joined #ste||ar
<mcopik> ajaivgeorge_: yes, the redefinition seems to be a problem
<ajaivgeorge_> mcopik: I should just remove the HPX_CONCEPT_REQUIRES from the redefinition right?
<mcopik> ajaivgeorge_: and the proj type
<ajaivgeorge_> That is done already. I mentioned it because hkaiser had mentioned it in the review.
<mcopik> ajaivgeorge_: if you any doubts or questions how to understand or resolve issues mentioned by Hartmut, please ask
<hkaiser> please, I might have overlooked something as well
<ajaivgeorge_> mcopik: of course. I will push a commit now correcting all the minor things. Transform will take time, I will try to get it done tomorrow (traveling today).
<mcopik> ajaivgeorge_: no worries
<mcopik> pull requests usually take few days

<heller> david_pfander: <jemalloc>: Error in dlsym(RTLD_NEXT, "pthread_create")
<heller> ha!
<heller> jemalloc 5.0
<david_pfander> heller: argh, really?! ...
<david_pfander> heller: I googled for issues, but didn't find anything...
<david_pfander> that was my exact error
<heller> yeah
<heller> give me a second...
<david_pfander> heller: which version of jemalloc are you using?
<heller> why would jemalloc even need pthread ... that's just wrong...
<heller> 5.0
<heller> just compiled it
bikineev has quit [Remote host closed the connection]
<david_pfander> heller: jemalloc master? or just some older commit?
<heller> jemalloc 5.0
<david_pfander> heller: ok, i'm building from master, that might be my problem
<david_pfander> heller: switching to 5.0... and testing :)
<david_pfander> heller: thanks a lot!
<heller> david_pfander: no, that error shows up with 5.0
<david_pfander> heller: but it builds for you, doesn't it?
<heller> yes, building is fine, it fails at runtime
<heller> looks like --disable-lazy-lock should be used
<heller> hmm, but it is :/
<david_pfander> heller: at least it confirms that it's not my stupidity :)

<david_pfander> heller: BTW the author of https://github.com/jemalloc/jemalloc/issues/907 mentions that jemalloc 4.5 worked for him, so switching to 4.5 might be an easy workaround
<heller> ok, 4.5 it is, as of now
<heller> david_pfander: you didn't experience any other errors on cori, right?
<heller> david_pfander: but yeah, using 4.5 solves the issue
<david_pfander> heller: for me, everthing works on cori
<heller> ok
<heller> self built jemalloc, I assume?
<david_pfander> heller: although today things are a bit strange
<heller> why?
<david_pfander> heller: yes, built everything myself
<david_pfander> heller: got some filesystem errors earlier
<heller> ugh
<heller> ok
<heller> so not my turf :P
