[MITgcm-support] misbehaving (?) outputs

[Julian Mak]

Dear all,

I have a slightly strange problem that I was wondering if anyone has 
suggestions on how to go about narrowing down the cause of problem. So 
the background is that I attempted a modification of the (admittedly a 
very out of date version of) layers package so that z(rho) and z^2(rho) 
may be time-averaged online, resulting in a measure of ePE ~ \int (gz^2 
/ 2) d\rho by doing some sums with the LAYERS_HU and LAYERS_HV variables 
(and copy and pasting chunks of code so I don't touch any of the 
existing diagnostics).

On my local machine(s), in serial mode and turning on both the 
LAYERS_UFLUX, LAYERS_VFLUX options, it spits out extra files LAYERS_ZU 
and LAYERS_ZV (along with ZZV and ZZU) that I compared with an offline 
diagnoses of LAYERS_HU and LAYERS_HV and both the data associated with 
the UFLUX and VFLUX options get written fine.

The odd thing then is that I put those modified files (layers_calc.F, 
layers_output.F, LAYERS.h) up on to a supercomputer (ARCHER) in parallel 
mode, and suddenly *all* the VFLUX outputs are messed up, but all the 
UFLUX stuff are as I expected and do in fact give believable results. 
Any suggestions??

Thanks,
Julian
