Detailed Description

FieldIO_Fortran class for file I/O of Field data in Fortran binary format.

This class reads configuration from binary data file generated by Fortran code. Before opening file, endian of the file must be specified using set_fileEndian() function. Only input from file is available. [28 Dec 2011 H.Matsufuru]

FieldIO_Fortran class provides file I/O of Field data in Fortran binary format. Fortran binary data record has heading and trailing bytes that represents length of the record. The size of heading and trailer is 4 (32bit) in this implementation.

File I/O is performed on the primary node (rank 0 usually), and the field data is gathered from/scattered to parallel nodes.

In this class, we assumed the data alignment as followes,

double U[NDIMENSION][NT][NZ][NY][NX][NCOLOR][NCOLOR][2]

(i.e. the rightmost index runs fastest)

[11 June 2012 S.UEDA]

Data layout is specified by format specified at constructor. The above corresponds to JLQCD layout.
