glite-mpi

in the following example, it is enabled the support for MPICH2 and OPENMPI; moreover the WNs are configured to use shared homes

############################################
# Mandatory parameters in services/mpi     #
############################################

# N.B. this file contains common configuration for CE and WN
# As such, it should be included in your site-info.def to ensure
# that the configuration of the CE and WNs remains in sync.

#----------------------------------
# MPI-related configuration:
#----------------------------------
# Several MPI implementations (or "flavours") are available.
# If you do NOT want a flavour to be configured, set its variable
# to "no". Otherwise, set it to "yes". If you want to use an
# already installed version of an implementation, set its "_PATH" and
# "_VERSION" variables to match your setup (examples below).
#
# NOTE 1: the CE_RUNTIMEENV will be automatically updated in the file
# functions/config_mpi_ce, so that the CE advertises the MPI implementations
# you choose here - you do NOT have to change it manually in this file.
# It will become something like this:
#
#   CE_RUNTIMEENV="$CE_RUNTIMEENV
#              MPICH
#              MPICH-1.2.7p4
#              MPICH2
#              MPICH2-1.0.4
#              OPENMPI
#              OPENMPI-1.1
#              LAM"
#
# NOTE 2: it is currently NOT possible to configure multiple concurrent
# versions of the same implementations (e.g. MPICH-1.2.3 and MPICH-1.2.7)
# using YAIM. Customize "/opt/glite/yaim/functions/config_mpi_ce" file
# to do so.

###############
# The following example are applicable to default SL 5.3 x86_64 (gLite 3.2 WN)
# Support for MPICH 1 is dropped
MPI_MPICH_ENABLE="no"
MPI_MPICH2_ENABLE="yes"
MPI_OPENMPI_ENABLE="yes"
MPI_LAM_ENABLE="no"

#---
# Example for using an already installed version of MPI.
# Just fill in the path to its current installation (e.g. "/usr")
# and which version it is (e.g. "6.5.9").
#---

# DEFAULT Parameters
# The following parameters are correct for a default SL 5.X x86_64 WN
#MPI_MPICH_PATH="/opt/mpich-1.2.7p1/"
#MPI_MPICH_VERSION="1.2.7p1"
MPI_MPICH2_PATH="/usr/lib64/mpich2/"
MPI_MPICH2_VERSION="1.2.1p1"
MPI_OPENMPI_PATH="/usr/lib64/openmpi/1.4-gcc/"
MPI_OPENMPI_VERSION="1.4"
#MPI_LAM_VERSION="7.1.2"

# If you provide mpiexec (http://www.osc.edu/~pw/mpiexec/index.php)
# for MPICH or MPICH2, please state the full path to that file here.
# Otherwise do not set this variable. (Default is to set this to
# the location of mpiexec set by the glite-MPI_WN metapackage.

# Most versions of MPI now distribute their own versions of mpiexec
# However, I had some problems with the MPICH2 version - so use standard mpiexec
MPI_MPICH_MPIEXEC="/usr/bin/mpiexec"
MPI_MPICH2_MPIEXEC="/usr/bin/mpiexec"
MPI_OPENMPI_MPIEXEC="/usr/lib64/openmpi/1.4-gcc/bin/mpiexec"


#########  MPI_SHARED_HOME section
# Set this variable to one of the following:
# MPI_SHARED_HOME="no" if a shared directory is not used
# MPI_SHARED_HOME="yes" if the HOME directory area is shared
# MPI_SHARED_HOME="/Path/to/Shared/Location" if a shared area other
#    than the HOME dirirectory is used.

# If you do NOT provide a shared home, set MPI_SHARED_HOME to "no" (default).
#MPI_SHARED_HOME=${MPI_SHARED_HOME:-"no"}

# If you do provide a shared home and Grid jobs normally start in that area,
# set MPI_SHARED_HOME to "yes".
MPI_SHARED_HOME="yes"

# If you have a shared area but Grid jobs don't start there, then set
# MPI_SHARED_HOME to the location of this shared area. The permissions
# of this area need to be the same as /tmp (i.e. 1777) so that users
# can create their own subdirectories.
#MPI_SHARED_HOME=/share/cluster/mpi


######## Intra WN authentication
# This variable is normally set to yes when shared homes are not used.
# This allows the wrapper script to copy the job data to the other nodes
#
# If enabling SSH Hostbased Authentication you must ensure that
# the appropriate ssh config files are deployed.
# Affected files are the system ssh_config, sshd_config and ssh_know_hosts.
# The edg-pbs-knownhosts can be use to generate the ssh_know_hosts
#
# If you do NOT have SSH Hostbased Authentication between your WNs, 
# set this variable to "no" (default). Otherwise set it to "yes".
#
MPI_SSH_HOST_BASED_AUTH=${MPI_SSH_HOST_BASED_AUTH:-"no"}

glite-mpi_ce

# Setup configuration variables that are common to both the CE and WN

if [ -r ${config_dir}/services/glite-mpi ]; then
 source ${config_dir}/services/glite-mpi
fi

# The MPI CE config function can create a submit filter for
# Torque to ensure that CPU allocation is performed correctly.
# Change this variable to "yes" to have YAIM create this filter.
# Warning: if you have an existing torque.cfg it will be modified.
#MPI_SUBMIT_FILTER=${MPI_SUBMIT_FILTER:-"no"}
MPI_SUBMIT_FILTER="yes"

glite-mpi_wn

# Setup configuration variables that are common to both the CE and WN
# Most variables are common to CE and WN. It is easier to define
# These in a common file ${config_dir}/services/glite-mpi

if [ -r ${config_dir}/services/glite-mpi ]; then

fi

munge configuration

• verify that munge is correctly installed:

# rpm -qa | grep munge
munge-libs-0.5.8-8.el5
munge-0.5.8-8.el5

• On one host (for example the batch server) generate a key by launching:

# /usr/sbin/create-munge-key

# ls -ltr /etc/munge/
total 4
-r-------- 1 munge munge 1024 Jan 13 14:32 munge.key

• Copy the key, /etc/munge/munge.key to every host of your cluster, adjusting the permissions:

# chown munge:munge /etc/munge/munge.key

• Start the munge daemon on each node:

# service munge start
Starting MUNGE:                                            [  OK  ]

# chkconfig munge on

software area settings

• Edit the file /etc/fstab by adding a line like the following:

cremino.cnaf.infn.it:/opt/exp_soft/ /opt/exp_soft/ nfs rw,defaults 0 0

• check nfs and portmap status

# service nfs status
rpc.mountd is stopped
nfsd is stopped

# service portmap status
portmap is stopped

# service portmap start
Starting portmap:                                          [  OK  ]

# service nfs start
Starting NFS services:                                     [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting NFS mountd:                                       [  OK  ]
Starting RPC idmapd:                                       [  OK  ]

# chkconfig nfs on
# chkconfig portmap on

• after any modification in /etc/fstab launch

mount -a

• verify the mount:

# df -h
