HP Fortran Release Notes Version 3.6 (5900-2344, August 2012)

+Oparallel_intrinsics
The +Oparallel_intrinsics option links in the parallel version of many of the Fortran intrinsics
located in libF90_parallel. However, libF90_parallel for Itanium-based systems is still only a serial
library. It will be parallelized in a future patch.
OUT OF FREE SPACE Error
The HP Fortran Programmer’s Reference states that the IOSTAT= and ERR= specifiers return error
913 (OUT OF FREE SPACE) when the I/O library attempts to use more memory than is available.
However, these specifiers do not detect all instances of error 913, especially those caused by
memory allocation failures in the I/O library.
NODEPCHK ignored
The NODEPCHK directive is sometimes ignored. The symptom was that programs which use the
directive do not parallelize as expected.
To parallelize your code, use another directive such as loop_parallel. In loops defined with
NODEPCHK, we recommend that you not invoke parallelism.
Compatibility information and installation requirements
This section describes system requirements for the installation and running of HP Fortran v3.6.
Software requirements
The HP Fortran v3.6 compiler requires approximately 546 megabytes (MB) of disk space. The
compiler requires approximately 326 MB of disk space and the remaining space is required for
other components such as the debuggers.
Hardware requirements
HP Fortran v3.6 is supported on hardware running HP-UX 11i v3 operating system.
Operating system requirements
HP recommends that you install HP-UX 11i v3 operating system for Fortran v3.6.
Installation requirements
To install HP Fortran v3.6, complete the following steps:
1. Start the swagentd daemon if it is not already running. Enter the following command in the
console window: /usr/sbin/swagentd
2. Use the swinstall command to install the desired products from the CD-ROM.
3. Enter the following command to install the Fortran compiler on HP-UX 11i v3:
/usr/sbin/swinstall -x rpc_timeout=9 -x mount_all_filesystems=false
-s /dev/dsk/c0t0d0/B3909DB
Support information on HP Fortran
HP customers who have purchased support contracts can find a list of HP Fortran language problems
and their fixes in the latest Software Status Bulletin (SSB). This information can be found by
referencing the product number B3909DB —HP Fortran Servers.
To display the product number and the release version of your HP Fortran compiler, enter the
following HP-UX command:
what /opt/fortran90/bin/f90
When you specify the +version option (entering f90 +version command), it displays the
compiler version information to standard output without compiling.
