[MITgcm-support] Missing/inconsistent output and stalled runs with ECCOv4 setup on ARCHER

[Dan Jones]

Hi all,

I tried a longer test run with singleCpuIO=.FALSE. in the &PARM01
namelist.  This run *did* produce STDOUT, pickup files, and mds output at
run-time, happily.  So you apparently need to run this configuration in
multiple CPU IO mode on ARCHER.

I'm still interested as to why this particular setup required
singleCpuIO=.FALSE., when all of my other runs (even large ones) worked
fine with singleCpuIO=.TRUE.,.  One possible answer: this setup uses EXCH2,
whereas my other setups do not.

Best,
Dan
