AIX

dear all,
I am trying to compile XL Fortran in AIX 5.3. Ibm has provided the Expansion pack CD which has xlfrte9.1 using which I am trying to do the compilation.
When I install it from the CD then I get the following success mesgs (not the complete list):

File:
I:xlfrte 9.1.0.0


xlfrte 9.1.0.0 (Selected)
XL Fortran Runtime Environment

xlfrte.msg.en_US 9.1.0.0 (Selected)
XL Fortran Runtime Messages - U.S. English

xlfrte.aix51 9.1.0.0 (Requisite)
XL Fortran Runtime Environment AIX 5.1 Libraries

As is clear from the above commands there is no binary generated in the /usr/bin. Also /usr/lpp/xlf has only lib directory having many files with .a extension. Also some library files are included in the /usr/lib which are as follows:

bash-3.00# ls libxlf*
libxlf.a libxlfpad_r.a libxlfpmt8.a
libxlf90.a libxlfpad_t.a libxlfpmt8_r.a
libxlf90_r.a libxlfpmt4.a libxlfpmt8_t.a
libxlf90_t.a libxlfpmt4_r.a libxlfpthrds_compat.a
libxlfpad.a libxlfpmt4_t.a libxlfutil.a

also /usr/lib/objrepos contains the object files...


With whatever information I could gather by now, I guess I am now supposed to link the library files using ld which will then generate the executable in the /usr/bin like xlf90, xlf95, f77 etc...

Kindly help me and guide me as to what should I do in order to make this fortran compiler work as this is the first dependency for the software in which I am interested?
Also the documentation states that bos.adt.libm is also required for the compilation of xlfrte 9.1 but the system doesnt have this rpm as well (i have checked it using lslpp -l bos.adt.libm) but since the compilation doesnt give the prereq error while installing xlf from the CD using smit and otherwise also so i really do not know if this is the real cause of the problem.

Eagerly waiting for the AIXperts views,

What you have installed is just the Fortran runtime, which can only run XL Fortran programs which have been already compiled.

IBM does not distribute the compiler for free, only the runtime is shipped with the expansion pack.

If you want to be able to compile Fortran code, you are going to have to purchase the IBM XL Fortran compiler. It looks like the latest version for AIX is XL Fortran Enterprise Edition 10.1 - the IBM program # is 5724-M13.

I believe that there is also a free g77 compiler that you can find online, but this would of course not be officially supported, as it is GNU.

IBM Maintains a library of precompiled tools at: http://www-03.ibm.com/servers/aix/pr.../download.html

Unfortunately, it looks like only the gcc and gcc-c++ compilers are there, not g77 -

Hope this helps.

hie,

Thanks you so much for your reply.

I got an evaluation copy of xlf10 from the IBM website and compiled the software which I wanted to compile using the parallel environment provided by MPICH-1.2.4

Actually, right now we cannot purchase AIX parallel environment, so I found out from many other places that people run MPICH also on AIX and with charmm too,and hence I have installed mpich-1.2.4 on the aix and ran the examples too to verify my installation of mpich.

The examples are working fine, but I observe a strange behaviour, with increase in the number of cpu the process becomes slow, or to put it in other words the communication among the cpu appears to be a problem.

This I observe for the test runs of mpich as well test runs of charmm.

I do not know if mpich is causing this problem or some other reason is responsible for it!


Kindly suggest me something regarding this too,
Eagerly Waiting,
