[MITgcm-support] nPx*nSx > 1000

[Martin Losch]

Hi there,

we are running I/O tests with a configuration of more than 1000 cpus/tiles (cs510 with nPx*nSx = 1350 tiles, to be precise). We would like to have each CPU do its own I/O, i.e. useSingleCPUio = .FALSE.,  but this does not work properly because for we get suffixes of ".***.001.data”  for tiles with tiles ids > 999 

I have it in the back of my head, that there is a flag that allows tile id numbers larger than 999. Is that so? What’s the name of this flag?

Martin
