Code_saturne 1.4b trouble [install]

Im pretty sure I use the scotch wrapper for metis - thats the only thing I found in the package-manager. (can you confirm this from the output?)

claus@claus-desktop:~$ ldd /opt/code_saturne/Enveloppe/ecs-1.4.a/arch/Linux/bin/cs_partition
linux-gate.so.1 => (0xb7f0d000)
libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0x4aa8a000)
libbft.so.1 => /opt/code_saturne/opt/bft-1.0.7/arch/Linux/lib/libbft.so.1 (0xb7ee7000)
libz.so.1 => /usr/lib/libz.so.1 (0x4aacd000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0x4a924000)
/lib/ld-linux.so.2 (0x44595000)


So please remind me; If I want to install Metis-4 during compile, I should extract metis to $cs_root/src/metis-4 and enter the path in 'setup' and answer 'yes' to use and 'yes' to install?

EDIT: I didn't read your answer well enough, I'll try to configure metis now <br /><br />Post edited by: Claus, at: 2008/11/12 15:47

I tried with Metis-4.0 now, but still get an error on the partitioner:

# Python is mandatory to launch the Graphical User
# Interface. It has to be compiled with Tcl/Tk/Tix
# support.
#
# It is highly recommended to use the Python provided

# the package manager if needed. The user can test if
# the installation process has been correctly done by
# typing in a Python prompt &quot;import Tix&quot;

# The following setup line will usually not be changed

# This package allows for hardware-optimized BLAS
# (Basic Linear Algebra Subroutines). If no system
# BLAS is used, we revert to an internal BLAS

#
# ATLAS (or another BLAS) should be available for most
# platforms through the package manager.
#
# Otherwise, only ATLAS installation on 32 bit systems
# is currently handled by this script.
#
# If using the Intel or IBM compilers, IMKL or ESSL
# may be used in place of ATLAS respectively.
# If so, Code_Saturne Kernel installation must be

# Optional packages:

#
# CGNS For CGNS file support

# Open MPI (or MPICH2) + Metis
#
# For massively parallel architectures, it is
# recommended to use the system's default

#
# If Open MPI is not chosen as the MPI
# distribution for the code, Code_Saturne
# Kernel has to be installed manually.
#
# For Linux workstations, MPI, HDF5, and even

# available on large systems such as
# IBM Blue Gene or Cray XT.
#
# Metis is more rarely found in Linux
# distributions, but may already be
# installed on massively parallel machines
# and on clusters. For good parallel
# performance, it is highly recommended.
# For meshes larger than 15 million cells,
# Metis 5.0 beta is recommended, as Metis 4
# may fail above the 20-35 million cells.
#
# If Metis 5.0 is chosen, its installation

Im unsure of what to do next.

It seems to be using Metis-4.0 from the compil.log (attached)

Maybe I should try to clear the entire installation, and begin again.


edit: The mesh is the mesh from the 'Stratified Junction' test-case. I just run that case to test CS-1.4

edit2: I tried completely reinstalling CS-1.4 but the partitioner still fails with 2 cpus.<br /><br />Post edited by: Claus, at: 2008/11/12 16:54
