Hi, Chris:

   Thank you very much for your quick response.
   I know there is settings for for AIX + Power3 in the patch8 genmake.
However, our system has different machine architectures such as IBM Power2,
Power3, PowerPC.We have only installed compilers on Power2 machines for
users use.

Can MITgcm Release 1 Patch 8 work on a IBM Power2 machine?

Thanks,
Honggao

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.

Chris

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.
