USAGE POLICY

Login, job submission, deployment of image

  • Select sites and clusters for experiments, using information on the Grid5000 network and the Status page
  • Access is provided via access nodes access.SITE.grid5000.fr marked here as accessible from everywhere via ssh with keyboard-interactive authentication method. As soon as you are on one of the sites, you can directly ssh frontend node of any other site:
access_$ ssh frontend.SITE2
  • There is no access to Internet from computing nodes (external IPs should be registered on proxy), therefore, download/update your stuff at the access nodes. Several revision control clients are available.
  • Each site has a separate NFS, therefore, to run an application on several sites at once, you need to copy it scp, sftp, rsync between access or frontend nodes.
  • Jobs are run from the frondend nodes, using a PBS-like system OAR. Basic commands:
    • oarstat - queue status
    • oarsub - job submission
    • oardel - job removal
Interactive job on deployed images:
fontend_$ oarsub -I -t deploy -l [/cluster=N/]nodes=N,walltime=HH[:MM[:SS]] [-p 'PROPERTY="VALUE"']
Batch job on installed images:
fontend_$ oarsub BATCH_FILE -t allow_classic_ssh -l [/cluster=N/]nodes=N,walltime=HH[:MM[:SS]] [-p 'PROPERTY="VALUE"']
Loading:
fontend_$ kadeploy3 -a PATH_TO_PRIVATE_IMAGE_DESC -f $OAR_FILE_NODES
A Linux distribution lenny-x64-nfs-2.1 with mc, subversion, autotools, doxygen, MPICH2, GSL, Boost, R, gnuplot, graphviz, X11, evince is available at Orsay /home/nancy/alastovetsky/grid5000.

Compiling and running MPI applications

  • Compilation should be done on one of the reserved nodes (e.g. ssh `head -n 1 $OAR_NODEFILE`)
  • Running MPI applications is described here
    • mpirun/mpiexec should be run from one of the reserved nodes (e.g. ssh `head -n 1 $OAR_NODEFILE`)

Setting up new deploy image

oarsub -I -t deploy -l nodes=1,walltime=12
kadeploy3 -e lenny-x64-nfs -f $OAR_FILE_NODES -k
ssh root@`head -n 1 $OAR_NODEFILE`

edit /etc/apt/sources.list

apt-get update
apt-get upgrade
apt-get install libtool autoconf automake mc colorgcc ctags libboost-serialization-dev libboost-graph-dev libatlas-base-dev gfortran vim gdb valgrind screen subversion


Compiled for sources by us:

  • gsl-1.14
./configure && make && make install
  • mpich2
./configure --enable-shared --enable-sharedlibs=gcc
make && make install

Mpich2 installed to:

Installing MPE2 include files to /usr/local/include
Installing MPE2 libraries to /usr/local/lib
Installing MPE2 utility programs to /usr/local/bin
Installing MPE2 configuration files to /usr/local/etc
Installing MPE2 system utility programs to /usr/local/sbin
Installing MPE2 man to /usr/local/share/man
Installing MPE2 html to /usr/local/share/doc/
Installed MPE2 in /usr/local
  • hwloc (and lstopo)

compile from sources. To get xml support install libxml2-dev and pkg-config

apt-get install libxml2-dev and pkg-config
tar -xzvf hwloc-1.1.1.tar.gz
cd hwloc-1.1.1
./configure && make && make install

Cleanup

apt-get clean
rm /etc/udev/rules.d/*-persistent-net.rules

Make image

ssh root@node tgz-g5k > $HOME/grid5000/imagename.tgz

make appropriate .env file.
