Using the UofA HPC Systems

Make sure you have NetID+ setup.
Request an account with instructor as PI by selecting UA HPC/HTC Accounts at the Using the Systems page.
Once your account as been approved, follow the directions at Connecting to HPC/HTC Systems to
```
    ssh login.hpc.arizona.edu
```
In a nutshell, use your netid+ password and select one of the options to accomplish the second part of the login process.

Copy one of the example code tar balls to the HPC system.

    // on HPC system
    $ pwd
    /path/to/dir/where/want/tar/ball/to/go
    
    // on CS linux machines
    cd /home/[instructorUsername]/cs620Files
    scp tarbalname.tgz netid@login.hpc.arizona.edu:/path/to/dir/where/want/tar/ball/to/go

First run the code interactively on the HPC system to check that you can get it to build and run.
- libration code:
```
module load perl; module load gnuplot; ./libration-check.pl < inputs.txt 
```

Then edit the first example PBS script at http://rc.arizona.edu/hpc-htc/using-systems/pbs-example. Make sure to change the job name, the email address to send information to, the group list to cs620spring2016, include the module load commands you need, change into the correct directory, and indicate how to run the executable as you did on the command line above. Here is a portion of the file:

### Load required modules/libraries if needed (blas example)
### Use "module avail" command to list all available modules
### NOTE: /usr/share/Modules/init/csh -CAPITAL M in Modules
source /usr/share/Modules/init/csh
#module load blas
module load perl
module load gnuplot

### set directory for job execution, ~netid = home directory path
cd ~mstrout/GettingStarted/libration-checking-perl-code

### run your executable program with begin and end date and time output
date
/usr/bin/time ./libration-check.pl < inputs.txt
date

Run qsub.
```
    qsub scriptname.pbs
```

Here are some useful commands we used at the tutorial session at the HPC center:

qstat -san -u username
module avail

For GPUs, you will want to use ElGato. The below is from Mike Bruck. ElGato is documented separately at http://elgato.arizona.edu/. It is an Astronomy/SISTA system operated by UITS Systems administration. It uses the LSF batch/scheduler system. The login node is accessed as:

ssh netid@elgato.hpc.arizona.edu
