Honggao,

 I believe the settings for -platform=SP3 should work for AIX + Power3.
 They are in the patch8 genmake. Let us know how you get on.

Dear Sir/Madam:

Our environment (CaSPer) at LSU consists of IBM RS/6000 AIX 4.3 systems
for interactive and batch work, as well as a cluster of 16
dual-processor IBM
RS/6000(SP) Power3 nodes for parallel work.

We are considering to install MITgcm Release 1 Patch 8 on our CaSPer for
a client. Could you tell me if MITgcm Release 1 can be installed on our
IBM AIX 4.3 systems? Also, do you have a parallel version of the
software for IBM AIX 4.3 is available?

I checked the script genmake located in the tools directory, there is no
settings for IBM AIX. I edited the genmake to specify the platform as
AIX case -platform: set platform=AIX breaksw

and then added machine setup corresponding to a IBM AIX machine into
Platform specific options as follow: case AIX*:
    echo "Configuring for " $platform
    set LN         = ( '/bin/ln -s' )
    set CPP        = ( '/lib/cpp -P' )
    set DEFINES    = ( ${DEFINES} '-DWORDLENGTH=4' )
    set FC         = ( 'xlf' )
    set FFLAGS     = ( '' )
    if ($?IEEE) set FFLAGS     = ( $FFLAGS '-ffloat-store' )
    set FOPTIM     = ( '-O3' )
    set LINK       = ( 'xlf' )
    breaksw

However, I failed to compile the source code.

"mdsio_reclen.f", 1516-036 (S) Entity wordlength has undefined type.
** mds_reclen   === End of Compilation 1 ===
1501-511  Compilation failed for file mdsio_reclen.f.

Could you tell me how to edit the genmake to make it work on our IBM AIX
system?

I am looking forward to hearing from you soon.
