Interactive Jobs (interactive job)

When you execute the qlogin command on the gateway node, a free login node will be allocated.

$ ssh gw.ddbj.nig.ac.jp
Enter passphrase for key '/home/your_account/.ssh/id_rsa': 
Last login: Sat Apr  9 16:53:55 2022 from XXX.XXX.XXX.XXX

Thank you for using NIG supercomputer system.
This is the gateway node, do not run program here.
Please use 'qlogin' to login to a login node.
---------------------------------------------------------------------

$ qlogin -l s_vmem=16G -l mem_req=16G

$

In this example, the login node at137 is allocated to the user, and you will see the prompt for at137 at the end. You can execute commands interactively from this prompt.

  • You can specify the amount of memory available by adding the -l s_vmem, -l mem_req options to the qlogin command. (On the general analysis division, 4GB memory will be allocated when you specify no options. On the personal genome analysis division, allocated memory depend on the configuration to use.)
  • The upper limit for memory that can be specified on the interactive node is approximately 96 GB. If you need larger than this, run a batch job on the compute node using the qsub command or contact . Also, depending on the congestion of the interactive node, you may be asked to conserve memory.
