By default, TakTuk use a tree to launch programs on all reserved nodes.
Using Taktuk to launch scripts
Starting to make a reservation:
|
users@frontale.site.grid5000.fr:
|
oarsub -I -l nodes=4 |
Now you should have:
|
|
users@node-15.site.grid5000.fr:
|
|
To launch scripts simultaneously on each node:
|
|
users@node-15.site.grid5000.fr:
|
taktuk -f $OAR_FILE_NODES broadcast exec [/home/site/user/testScript.sh] |
Note: do not forget to type the characters [ and ]}
By default, Taktuk displays a lot of informations but it is not always necessary. So you can add some options on command line to modify correctly the output:
-o connector -o status -o output='"$host: $line\n"'
Example:
To known if time is synchronised on each node (Result formated correctly)
|
|
users@node-15.site.grid5000.fr:
|
taktuk -o connector -o status -o output='"$host: $line\n"' -f $OAR_FILE_NODES broadcast exec [date] |
[plemoine@frontale plemoine]$ oarsub -I -l nodes=5 Host:Port = frontale.bordeaux.grid5000.fr:54442 IdJob = 37679 Interactive mode : waiting plemoine@node-101:/home/bordeaux/plemoine$ taktuk -o connector -o status -o output='"$host: $line\n"' -f $OAR_FILE_NODES broadcast exec [date] | uniq 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:
