Detailed Description

FieldIO_Binary_Parallel class for file I/O of Field data in binary format using MPI parallel I/O.

The file format treated in this class is the same as ILDG file format, while not packed to LIME file. The endian is big as the definition of ILDG file. [28 Dec 2011 H.Matsufuru]

FieldIO_Binary_Parallel provides file I/O of Field data in binary format. File I/O is performed in parallel relying on MPI I/O. The interface is defined in the FieldIO base class, and this class defines concrete realisation.

Parallel I/O is enabled when USE_MPI option is turned on; otherwise this class is an alias of FieldIO_Binary that provides serial I/O.

Simultaneous use of BGNET and MPI requires some care: prescription by T.Doi was incorporated. [16 Sep 2014 H.Matsufuru]
