Short Explanation about how it work
By default, TakTuk uses a tree to launch programs on all reserved nodes. it initiates a few connections in parallel (the deployment window) and distributes the remaining deployment work to already deployed peers using an adaptive work-stealing algorithm (Extract of A guide of TakTuk use by Guillaume Huard).
Using TakTuk with the base environment
Prerequisites
Starting with a reservation:
|
users@frontale.site.grid5000.fr:
|
oarsub -I -l nodes=4 |
Now you should have:
|
|
users@node-15.site.grid5000.fr:
|
|
Using Taktuk to launch scripts
To launch scripts simultaneously on each node:
|
|
users@node-15.site.grid5000.fr:
|
taktuk -f $OAR_FILE_NODES broadcast exec [/home/site/user/testScript.sh] |
Note: do not forget to type the characters [ and ]
By default, Taktuk displays a lot of informations but it might not be necessary. So you can add some options on command line to modify correctly the output:
-o connector -o status -o output='"$host: $line\n"'
Example:
To know if time clock are synchronised on each node (Result formated correctly)
|
|
users@node-15.site.grid5000.fr:
|
taktuk -o connector -o status -o output='"$host: $line\n"' -f $OAR_FILE_NODES broadcast exec [date] |
Output
node-101.bordeaux.grid5000.fr: Fri Mar 23 09:38:46 CET 2007 node-23.bordeaux.grid5000.fr: Fri Mar 23 09:38:46 CET 2007 node-24.bordeaux.grid5000.fr: Fri Mar 23 09:38:46 CET 2007 node-67.bordeaux.grid5000.fr: Fri Mar 23 09:38:46 CET 2007 node-97.bordeaux.grid5000.fr: Fri Mar 23 09:38:46 CET 2007
To know cpu's installed on nodes:
plemoine@node-101:$ taktuk -o connector -o status -o output='"$host: $line\n"' -f $OAR_FILE_NODES broadcast exec ["cat /proc/cpuinfo | grep 'model name'"] | uniq
Output
node-101.bordeaux.grid5000.fr: model name : Intel(R) Xeon(TM) CPU 3.00GHz node-23.bordeaux.grid5000.fr: model name : AMD Opteron(tm) Processor 248 node-24.bordeaux.grid5000.fr: model name : AMD Opteron(tm) Processor 248 node-67.bordeaux.grid5000.fr: model name : Intel(R) Xeon(TM) CPU 3.00GHz node-97.bordeaux.grid5000.fr: model name : Intel(R) Xeon(TM) CPU 3.00GHz
Using TakTuk with your own environment and no taktuk installation on it
Prerequisites
Starting to make a reservation:
|
|
users@frontale.site.grid5000.fr:
|
oarsub -I -l nodes=4 -q deploy |
Deploy environment:
|
|
users@frontale.site.grid5000.fr:
|
kadeploy -p part -f $OAR_FILE_NODES -e sid-x64-nfs-1.0 |
Using Taktuk to launch programs
To execute command as root for update , you have to use the following option: "-l root" as the first one used on the command line:
|
|
users@frontale.site.grid5000.fr:
|
taktuk -l root -s -o connector -o status -o output='"$host: $line\n"' -f $OAR_FILE_NODES broadcast exec ["apt-get update"] |
