remapnn from ORAP5 1442x1021 to 360x180 very slow (@3hours for one var, one month of monthly means)
Added by judy hertz over 8 years ago
Hi all,
I'm remapping (nn) ORAP5 monthly means 1442x1021 to 360x180, and even with
-P 8it's taking approx. 3 hours per monthly file. Does anyone have suggestions on how I might speed up the remapping -- even an alternative/faster method?
thanks in advance --judy

Hi Judy,
Which CDO version are you using?
We have replaced the NN search algorithm in CDO version 1.7.0 to a much faster method.
Cheers,
Uwe

Thanks very much for the quick reply. I'm using 1.6.8, will switch to 1.7.0 and report back. Cheers! judy

One last question -- I just learned there is a 1.7.2 release, I assume this would keep me more current?

Yes, please use the most recent CDO release you can!

We installed 1.7.0 for now and went from 3 hours to 3 minutes in processing a monthly 1442x1021 file! My apologies for not keeping up with the releases and taking up your time unnecessarily. We really appreciate your work on CDO, I use it every day!
