Sample programs demonstrating the ability to compress/decompress data on the flywhen writing to or reading from a file in Fortran using named pipes (FIFOs).

• Set your compiler inMakefile (ifort,gfortran orf77)
• Runmake

Run:./write <N> [F] [L]
where:
N - number of lines to write to the file [required]
F - compression filter (gzip,pigz,lz4c,lzop) [optional]
L - compression level (from-1 to-9) [optional]

Data will be written to thedata.* file.If no compression filter is specified, data will not be compressed.

Run./read [F]
where:
F - compression filter (use the same as for writing) [optional]
