Re: [eigen] CDASH-Speedup: "Homer" how did you do it?

[ Thread Index | Date Index | More Archives ]


Is it possible to change the compiler settings at the outermost level, the calling batch? I would think it should be, but I did not see how. All my experiments (even with EI_OFLAGS=...) fail.
A preferable result could be something in the (batch-)lines of e.g.:

set CXX_VERSION=msvc-2008(9.0.30729.1)

what do you think?

Ok, my build times are a little bit long (well ridiculously long) but
that could have tons of reasons. Processor, OS, HD and even compiler
flags. Actually, the build you are referring to has been build with
/Ox as opposed to /O2. I wiltl try to rebuild with the current setings
- lets see what is going to change.

Hi "Homer",

I want to ask you for the steps you have done from cdash test runs this
afternoon to tonight.

May setup is (or maybe i probably have to say was) similar to yours
(Vista+MSVC etc) and it is relatively very slow.
What is to do, to get the a speedup similar to yours in the past few
in the cdash suite?

Frank (cdash: "Gordo")

Thank you Hauke,
running the complete cdash testsuite only takes roughly half the test time
(from 22 min down to 11 min) .
This is fine.

But there is still a big gab remaining:
"Homer" 27.08.09 test time  2.4 min (build time 57.5 min !!!!)
compared to
"Gordo" 29.08.09 test time 11.2 min (build time 16.5 min)

CDash is not a benchmark arena and a testsuite is not meant to be quick,
but i would love to understand the reasons (and avoid build times in terms
of hours).
