<font size="-1">Hey guys,<br>
<br>
First thanks Christian for helping with my previous issue (I never
got email link to reply).<br>
<br>
I've been working on a new modeling system to replace CASAL
(produced by NIWA in New Zealand). CASAL was built using ADOLC 1.8
in a custom solver (FMM). I've re-implemented this same solver
with ADOLC 1.8 and 2.5 as different minimisers in my new model but
the speed differences between the two is HUGE.<br>
<br>
Minimisation with ADOLC 1.8 + FMM = 4 seconds<br>
with ADOLC 2.5 + FMM = 2.5 minutes<br>
with Numerical Diff (no autodiff) = 4 seconds<br>
<br>
This is a simple model but the differences in ADOLC speed is
amazing. My interface method with ADOLC is:
<a class="moz-txt-link-freetext" href="http://pastebin.com/WGyZLRan">http://pastebin.com/WGyZLRan</a> <br>
A single iteration with 2.5.2 takes 3-4 seconds. All binaries
minimise to the same result.<br>
<br>
Is there any reason why ADOLC 2.5 would be that much slower than
1.8? <br>
Is there any way I can increase the speed of ADOLC? <br>
I notice it writes to files A LOT and not a huge amount of data
(any flags to keep this in memory?)<br>
<br>
<br>
<br>
Thanks,<br>
Scott<br>
