I missed the actual change from compose_cb to small_vector
<heller_>
Do you know when small_vector was included in boost container?
<K-ballo>
1.5x?
<K-ballo>
1.58
<heller_>
Yup
<heller_>
Ok.. noone checked and now our 1.56 builders fail

hkaiser: upgrade minimal boost version, revert the compose_cb patch it write our own small_vector?
eschnett has joined #ste||ar
<hkaiser>
heller_: what would be the minimal boost version required?
<zao>
:D
<K-ballo>
55 -> 58
<hkaiser>
I think we can do that
<hkaiser>
what do you guys think?
<heller_>
I agree
<heller_>
We should do that
<hkaiser>
ok, let's go ahead with this, then
<hkaiser>
docs, config.hpp, rostam

<heller_>
Let's check what the various distros ship though
gedaj has joined #ste||ar
<hkaiser>
k
<hkaiser>
heller_: alternatively we can leave the old compose_cb in for older boost versions
<hkaiser>
third option would be to look for a 3rd party implementation of the small_vector idea
<hkaiser>
where 3) is almost the preferrable solution ;-)
<zao>
Boost versions, aren't they lovely?
<hkaiser>
they are
<zao>
We found the reason for a memory leak in OpenFOAM after months of troubleshooting...
<zao>
Boost 1.64 (bad) vs. Boost 1.61 (good).
<hkaiser>
nice
<K-ballo>
how?
<K-ballo>
was the leak directly caused by boost?
<zao>
Didn't dig deeper, but that's the only change between the working and bogus build.
<zao>
Lovely codebase that has those null references and all.
<K-ballo>
"empty lvalues" ;)

hkaiser: have I asked you before to send me info about phylanx? I spent time this week with the guys from UT in the dongarra group and it looks like I may start porting some of their new exascale matrix work to hpx.
<jbjnr>
I'm curious to know what you are doing with matrices in phylanx
<jbjnr>
I'm sure I asked before. must check emails ...
<hkaiser>
jbjnr: I have not responded to this, sorry
<hkaiser>
best would be to talk over skype at some point
