Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

You could drop the 'gcc' and 'gfortran' options, and use the default xlC compiler toolchain. I believe that is expected to provide better performance on POWER hardware, though the NAMD developers would have to confirm that.

So that we can fully understand your situation, could you please describe what resources led you to choose the lapi-gcc-gfortran build target?

Dear,

As I want to compile NAMD2.9 in AIX UNIX, I have to compile charm first.

This is my command:
./build charm++ lapi gcc   gfortran     --with-production

This is my error:

g++: error: unrecognized command line option '-qstrict'
Fatal Error by charmc in directory /rc/home/wang/mzhu6/bin/NAMD_2.9_Source/charm-6.4.0/lapi-gfortran-gcc/tmp
   Command g++ -fPIC -Wno-deprecated -DCMK_GFORTRAN -I../bin/../include -D__CHARMC__=1 -I. -O3 -qstrict -Q -c trace-common.C -o trace-common.o returned error code 1
charmc exiting...

What can I do?

Best regards,

Mengyuan Zhu
