Indeed. Thank you for suggesting and modifying the code to do such. Nowadays, I am very conscious of the memory needs for a particular application. I coded some estimate of dynamic and automatic memory requirements. Obviously, I/O is a bottleneck as the number of CPUs increased in the distributed memory paradigm. I am studying alternatives, but I haven't found a satisfactory strategy yet. Applications like data assimilation are I/O intensive.

  • Ticket #784 – Description

    initial v1  
    1 It may be worth noting that INLINE_2DIO and PERFECT_RESTART are incompatible, because nf_fread4d.F and nf_fwrite4d.F are not configured for INLINE_2DIO. This incompatibility can cause crashes due to insufficient memory during reading and writing of restart files if the problem is indeed memory constrained.
