unix - Bypassing Linux cluster gateway - going directly to node from your desktop -


from desktop executing command go linux cluster:

i have in .bash_profile

alias gothere="ssh -i ~/.ssh/id_rsa_macmini_mine pdubois@thelinux.cluster.co.jp"

then call go cluster:

dhcp190-206:~ pdubois-macmini$ gothere last login: tue mar 25 15:41:03 2014 dhcp190-206.mycompany-u.ac.jp [pdubois@thelinuxcluster ~]$

then once reach gateway of cluster again go node:

alias blogin="bsub -is -q intj bash -l"

call way go node:

[pdubois@thelinuxcluster ~]$ blogin  job <221825> submitted queue <intj>. <<waiting dispatch ...>> <<starting on clusternode61>> [pdubois@clusternode61 ~]$

my question is, there way can simplify above 2 steps 1 step? can go directly cluster node desktop.

the ssh login user node (gateway called it) on cluster, bsub -i interactive job submission request puts on cluster running interactive job on compute node.

so no, can't combine these two. interactive job started user node.

perhaps more importantly, once login "gateway", "on" cluster programming , debugging purposes. access nodes should reserved job submission , interactive debugging jobs. once run bsub command, account being charged time on machine.
