CHOMBO
CHOMBO
Introduction
Installation
This page describes what I (Gethin) did to install and run CHOMBO. In the first instance, I worked on dyln (an x86_64 machine) and used the GNU C and Fortran compilers (gcc, g++ and gfortran).
First we will look at the prerquisites, HDF5 and an MPI implementation, and then CHOMBO itself.
HDF5 v1.4.4
./configure --prefix=/gsb6/ggdagw/hdf5/hdf5-1.4.4/serial --enable-production
MPICH v1.2.5
from:
ftp://ftp.mcs.anl.gov/pub/mpi/old
treating dylan as an SMP machine:
./configure --prefix=/gsb6/ggdagw/mpich/mpich-1.2.5/ch_shmem --with-device=ch_shmem
- test with hello_world: OK, but mpif77 (or 90) was not created during build.
let's try ch_p4 also..
./configure --prefix=/gsb6/ggdagw/mpich/mpich-1.2.5/ch_p4 --with-device=ch_p4
- hello world does not work--perhaps need to start a daemon? Go with shmem for the moment.
CHOMBO
Oct07 release
Without HDF5
Chombo-2.0/lib/mk/Make.defs.local
DIM = 2 DEBUG = TRUE OPT = TRUE PRECISION = DOUBLE PROFILE = FALSE CXX = g++ FC = gfortran MPI = FALSE USE_HDF = FALSE
make lib make test make run Looks like the tests pass BUT uses -m32 during compilation.
With HDF5 compiled in serial mode
USE_64 = TRUE
adds -m64 to the GNU compiler flags and so object code is created for the x86_64 architecture, and so it will link against the HDF libraries which are built for x86_64. This is not what the documentation says the makefile variable is for! Hey ho. Add it in.
- export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/gsb6/ggdagw/hdf5/hdf5-1.4.4/serial/lib
required to find shared object files, else tests will not run. Tests look OK.
