PuTTY questions

[SDPA_Pet]

Hi, I am new to PuTTY. I need to use it to connect a remote cluster super computers to run blast. I have several questions.

1>It will take several days until the BLAST finished, but I need to turn off my labtop. What is the proper way to do it? -- After I close PuTTY on my labtop, make sure the PuTTY still running on the clusters.

2> What command can let me check how many cpus (cores) that I can use on clusters.

3>While the BLAST is running, is it possible for me to log on the remote cluster again and run another program with same ID.

Thanks.

The cluster you are using should have a proper job queuing/scheduling system (if it is a supercomputer). You submit the jobs via the scheduling system (LSF/PBS/SGE) which then takes over job management allowing you to log out/back in as you need.

2> What command can let me check how many cpus (cores) that I can use on clusters.

These settings are cluster specific and determined by system administrators. Ask for local help.

3>While the BLAST is running, is it possible for me to log on the remote cluster again and run another program with same ID.

See answer for #1. Jobs submitted via a scheduler run independently. You can potentially schedule tens of jobs (via scripts) and they will generally pend/run depending on limits associated with your user ID/group (set by local cluster administrators).
