Not sure if that answers your questions but once upon a time we here
at Berkeley tried to write a some sort of document that was supposed
to answer questions like this. Attached. By no means it is complete,
up-to-date, etc, but it might be worth reading for anyone who
contributes to cctbx. (Even not sure if I'm sending the latest
version).<br>
Unfortunately, nobody bothered to put it in some central place.<br>

<div>It looks like the errors are related to random number
generation. For a given seed, would the sequence of
numbers change when Boost is changed? I did a diff between
Boost 1.56 and the current Boost and could not see any
changes that immediately stood out as being related to
random numbers.</div>

<div>everybody seemed to agree but then it
was proposed to move straight to Boost
1.60, and this caused troubles. Could we
consider again to move to at least 1.56?
As far as I can tell, this does not
cause any issue and as stated one year
ago, it would help me and Olex 2.</div>

<br>
I have improvements to the
smtbx on their way to be
committed which require
Boost version 1.56. This is
related to Boost.Threads,
whose support I re-activated
a few months ago on Nick�s
request. I need the function
boost::thread::physical_<wbr>concurrency
which returns the number of
physical cores on the
machine, as opposed to
virtual cores when
hyperthreading is enabled
(which it is by default on
any Intel machine). That
function is not available in
Boost 1.55 which is the
version currently used in
the nightly tests: it
appeared in 1.56.<br>
<br>
So, would it be possible to
move to Boost 1.56?
Otherwise, I will need to
backport that function. Not
too difficult but not
thrilling.<br>
<br>
Best wishes,<br>
<br>
Luc<br>
