Whenever the NAG Parallel Library has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
This implementation is a compiled, tested, ready-to-use version of the NAG Parallel Library that is considered suitable for operation on the computer systems detailed below:
hardware: Sparc Ultra systems operating system: SunOS 5.10 (Solaris 10) and compatible Fortran compiler: Sun Studio 11 Fortran 95 8.2 and compatible MPI: Sun ClusterTools 7 and compatible
For information about implementations of the NAG Parallel Library for use on other computer systems please contact NAG.
This implementation was produced at the Sun Porting Centre on the computing system detailed below:
hardware: Sun Fire V890+, UltraSPARC IV+, 1500MHz, 24 cores operating system: Solaris 10 Update 3 Fortran compiler: Sun Studio 11 Fortran 95 8.2 compiler options: -fsimple=1 -xvector=no -ftrap=%none -KPIC -xarch=v9a -dalign -stackvar -O4 C compiler: Sun Studio 11 C Compiler 5.8 compiler options: -DAdd_ -xarch=v9a -KPIC -O MPI: Sun ClusterTools 7 BLAS: Sun Studio 11 Sun Performance Library
It was also tested at NAG Ltd on the system detailed below:
hardware: Sun Fire 880, UltraSPARC III, 900MHz, 8 cores operating system: Solaris 8 Fortran compiler: Sun Studio 9 Fortran 8.0 C compiler: Sun Studio 9 C Compiler 5.6 MPI: OpenMPI 1.2 BLAS: Sun Studio 9 Sun Performance LibraryThree archive libraries are supplied, libnagmpi.a, libnagmpi_nag.a and libnagmpi_spl.a plus shared versions of them in libnagmpi.so, libnagmpi_nag.so and libnagmpi_spl.so.
The supplied archive library libnagmpi.a (and the shared version libnagmpi.so) includes the Fortran MPI version of the Basic Linear Algebra Communication Subprograms (BLACS v1.1, with patch03 dated February 24, 2000). All libraries were compiled with full optimization (-O4).
This implementation has been tested using the Basic Linear Algebra Subprograms (BLAS) provided in Sun Performance Library and also tested using BLAS supplied by NAG (in libnagmpi_nag.a).
For further details, refer to other documentation supplied or contact NAG (see Section 6).

To install all material use the Unix tar utility, e.g.
tar xvf /cdrom/fd03.tar(assuming the CD-ROM has been mounted as /cdrom).
Links to the archive and shared libraries libnagmpi*.* may be placed in a directory, such as /lib/64, in the default search path of the linker so that linkage is convenient.
The script nagmpiexample is intended to provide users with a simple means of access to the example material. It will require some minor edits to reflect the local installation and should be placed in a directory, such as /usr/local/bin, which is on users' execution search paths. By default, the script nagmpiexample links with the recommended library libnagmpi_spl.a which makes calls to routines from the installed Sun Performance Library. For checking purposes you may want to link to the library libnagmpi_nag.so which replaces calls to the Sun Performance Library by internal calls; in this case, in nagmpiexample, -lnagmpi_spl should be replaced by -lnagmpi_nag and you should set blaslink="".
The installer should ensure that the users' environment is set up so that they can compile, link and execute (with the mpif77 and mpirun commands provided by Sun Cluster Tools 7) an MPI Fortran program. This is usually accomplished by setting the relevant environment variables (PATH and LD_LIBRARY_PATH) to the correct values in a script that gets executed at shell startup time. If one relies on the LD_LIBRARY_PATH environment variable, it is imperative that it is set at shell startup time otherwise mpirun will fail, with a typical message "error while loading shared libraries".
To install the Library Manual, use the tar utility, e.g.
tar xvf /cdrom/pdf.tar(assuming the CDROM had been mounted as /cdrom).
You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make them readily available to users.
For example, give the command
nagmpiexample f04ebfpto run the F04EBFP example program. Almost all the example programs have 4 processes. nagmpiexample uses mpirun (provided by Sun ClusterTools 7) to run the processes.
The following material should also be made accessible to users:
documentation files:
The nagdoc_fd03 directory contains the Library Manual. This should be made available to users.
compiled libraries:
libnagmpi.a libnagmpi_nag.a libnagmpi_spl.a libnagmpi.so libnagmpi_nag.so libnagmpi_spl.soexample program material:
examples/source/*e.f examples/data/*e.d examples/results/*e.r scripts/nagmpiexample
Making the supplied example material directly available to users provides them with easily adaptable templates for their own problems.
On-line documentation is bundled with this implementation. Please see Section 4.
The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service.
The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times.
When contacting a Response Centre, it helps us deal with your enquiry quickly if you can quote your NAG site reference and NAG product code (in this case FDSO603DM).
