porting binary data files from HP-UX (PA-RISC) paltform

[Michal_Kvasnicka]

Hi,

could you recommend me some methodology, how to transfer fortran77 code and corresponding binary data files (read by direct access) from HP-UX c80 B.11.11 U 9000/785 platform to the Linux86_64 (Intel/AMDplatform with INTEL Fortran 11.1 compiler.

My main problem is the reading (via direct access) of the binary data files which were created on HP-UX.

Thanks in advance,

Michal

Hello Michal,

HP RISC machines are big endian, x86 is little endian. If youbuild with ifort then youshould use the F_UFMTENDIAN=big environment setting for binary files. That should do it, no recompilation needed. You can even specify which unit number should or should not be converted.

Cheers

The right way how to play with big_endian (HP-UX, PA_RISC) binary files is:

1. setup environment variable via shell command: export F_UFMTENDIAN=big
2. use the following compiler option: -assume byterecl

My preference would be to OPEN the file with CONVERT="BIG_ENDIAN" if you can change the source. -assume byterecl is needed only if RECL= appears in the OPEN for the unit and the program assumes that the RECL= units are in bytes.
