how to run NEURON in supercomputer

Post by yuyuguo » Tue Feb 12, 2008 10:18 am

I asked this question, and got very nice answer from Mike and Tom.
This might be helpful for other people, so I post here:

Hello Yugo,
Building instructions for supercomputers tend to be idiosyncratic but
neuron is generally build with graphics, terminal capabilities, and
other interactive modules turned off via the configure options:

--without-x --without-readline --without-memacs

many supercomputers do not allow shared libraries so you would need

--disable-shared

you certainly want to use communication between processors so you
definitely need

--with-paranrn

But the biggest question is whether the supercomputer uses the
same compilers as the login machine from where you launch the
job. If not then you need to cross compile. And that means
building/installing first with the "--with-nmodl-only" with proper
CC and CXX environement variables and then building/installing with
"--without-nmodl" and the CC, CXX, MPICSS and MPICC environment
variables properly set. As an example, for the Pittsburgh Cray XT3
the process is

../nrn/configure --prefix=`pwd` \
'--srcdir=../nrn' --with-nmodl-only --without-x CC=gcc CXX=g++

make
make install

../nrn/configure --prefix=`pwd` \
'--srcdir=../nrn' '--without-x' '--without-memacs' '--without-readline'
\
'--disable-shared' '--with-paranrn' '--without-nmodl' \
CC=cc CXX=CC MPICC=cc MPICXX=CC linux_nrnmech=no \
java_dlopen=no \
am_cv_CC_dependencies_compiler_type=dashmstdout \
am_cv_CXX_dependencies_compiler_type=dashmstdout \
--host=x86_64-unknown-linux-gnu

make
make install

--------------
Do NOT try to use nrnoc. That contains such a small subset
of NEURON functionality that it is unusable in practice.

We will be happy to help you with your installation.
-Michael
