LoBoS Pack Parallel Supercomputer User Setup

New User Setup

How:

New users must take the following steps in order to successfully submit jobs to the LoBoS queue.

1.

Edit your .rhost file (~/.rhost) and add all of the computers within LoBoS. All of the computers are defined in the rhost_additions.txt file in the correct rhost format. You may insert the rhost_additions.txt file and then do a global replacement of "your_user_name" with your user name. You may confirm that this is working by performing an rlogin to master2.lobos.nih.gov. You should NOT be prompted for your password.

2.

Make sure that you have access to the lobosq2 command. This may be accomplished by typing "lobosq2 list" followed by a < CR > at the UNIX prompt. You should observe something like this:

# Job Status Date:Wed Oct 15 11:49:31 1997
# Queue Score: 50544000.000000
# job id                   uid gid pri CPUs      Start Time       Est Time Act Time assigned cpus
#xxxxxxxxxxxxxxxxxxxxxxxx xxxx xxxx xxx xxxx yyyy mmm dd hh:mm:ss hhh:mm:ss hhh:mm:ss xxxxxxxxxxxxx

If you do NOT observe something similar or receive a "command not found" message you may install the lobosq2 script in the PATH on your computer. If you do not have system priveledges you may send email to billings@helix.nih.gov .

3.

Make sure that you have access to the LoBoS machines. Execute "rlogin master2", and then look at your home directory with "ls -l". Your current working directory should be the same as your home directory. If it is not, your directory will have to be added to the automount maps.

Your account is now set up to use LoBoS !!!

Why:

The previous steps are necessary because LoBoS has been implemented with the following assumptions:

1. Each user is able to login directly to each of the master and processing nodes.
2. Each user has access to the lobosq2 command.
3. Each user's home directory may be automounted from any of the LoBoS nodes.
