[ecco-support] Cost function calculation problems when changing number of cores in ECCOv4-r4

Wed Dec 30 13:34:22 EST 2020

[Reposting, forgot to change subject line in last email]

Hi Ou and Patrick,

Thanks for your quick replies. I've been modifying data.exch2 (i.e.

different core numbers, so hopefully that part is okay.

Here's one of the STDOUT files from a run with 360 cores:

Thanks,
Dan
