Subject: [Beowulf] Amber 8 Execution problem
Hi Sangamesh,
Sounds like a linking problem rather than execution ...
Hi All,
I installed AMBER8 on Opteron Dual core, dual processor, Rocks
cluster with the following options/libraries:
Compiler: Intel 9 Fortran and C++ compilers.
Blas Library: MKL8
MPI: MPICH2 compiled with Intel compiler.
its giving:
symbol lookup error: undefined symbol:
__intel_cpu_indicator
I guessed, this might relate to MKL library.
Sounds like a safe bet.
During 'make' it was taking MKL lib*.so files from
$MKL_HOME/lib/32 (in config.h file).
Changed $MKL_HOME/lib/32 to $MKL_HOME/lib/64 since the arch is
AMD64 opteron.
But it is giving incompatible - libvml.so file.
I'm not getting why this error is coming.
The MKL library is highly targetted at Intel CPUs and you are using AMD
Opteron.
Unlike Intel, AMD offers a free math library tuned to their processors:
ACML.
http://developer.amd.com/acml3.jsp
is the free download page. Choose a version compatible with your Intel
Fortran compiler.
That is probably your easiest solution and the way to the best
performance on Opteron.

Any help for this will be appreciated.
Thanks & Regards,
Sangamesh
