Hey BAndiT1983 !
16:47
TofuLynx
How are you?
16:47
BAndiT1983
hi TofuLynx
16:47
BAndiT1983
fine, and you
16:47
BAndiT1983
?
16:47
TofuLynx
Me too :)
16:47
BAndiT1983
nice to hear
16:47
TofuLynx
Do you have any suggestion for me before I start diving into openMP?
16:48
BAndiT1983
nothing specific yet, besides release mode for testing timings, also split the loops so it's easier to test different approaches, e.g. do it in linear way, without nested loop for x and y
16:49
TofuLynx
I meant, for learning openMP xD
16:50
BAndiT1983
ah, you mean resources
16:50
BAndiT1983
google is full of it, but i can search some which i've used before
16:50
TofuLynx
Yeah, exactly :D

BAndiT1983
used them before, nice references
16:53
TofuLynx
Thank you!
16:55
BAndiT1983
no problem
16:56
TofuLynx
Ok
16:56
TofuLynx
so basically, before I modify the code, I should benchmark every demosaicer
16:57
TofuLynx
in release mode
16:57
TofuLynx
and several times, correct?
16:57
BAndiT1983
yep
16:57
TofuLynx
okkey
16:57
BAndiT1983
but you can also do another way
16:57
TofuLynx
via unit tests?
16:57
BAndiT1983
you copy every debayer processor and rename the copy to e.g. BilinearDebayerOMP
16:58
BAndiT1983
then modify it, add unit tests and off you go
16:58
TofuLynx
Interesting
16:58
TofuLynx
good idea
16:58
BAndiT1983
we can keep better implementations
16:59
TofuLynx
and avoid losing the working code.
16:59
TofuLynx
without having to go back using git
16:59
BAndiT1983
yep, exactly my thoughts
