-Listed below are instructions for setting up accounts on DT1/DT2.
-Instructions:
-Listed below is a set of instructions I typically give new students that will be using the computational clusters on campus (deepthought1, DT1 and deepthought2, DT2).  You will assigned one or both clusters based on your simulation needs by Dr. Klauda.  These instructions work for both, so do these on the cluster(s) you are assigned.
-I have submitted a request to add you as a user to my account on DT1 and/or DT2. Once this is done, you should get a generic email from IT regarding the resource.
-As for setting up your account, I have listed below some instructions. I first need your UMD username (terpmail) to setup your account.  Details of this cluster can be found:
-http://www.oit.umd.edu/hpcc/
-Now for the cluster setup:
-If you are not familiar with the use of LINUX, I would first go through some on-line tutorials for commands to use in LINUX. To login to DT1 (login.deepthought.umd.edu) or DT2 (login.deepthought2.umd.edu) with Windows you will need to have PuTTY to connect to deepthought:
-http://www.chiark.greenend.org.uk/%7Esgtatham/putty/
-And the following program will be useful to transfer files between deepthought and your computer
-http://winscp.net/eng/index.php
-Built-in commands for MAC users can be used to connect via the command line (scp) and apps for file transfer (eg, cyberduck).
-Then, take a general look at the website of the HPCC OIT to get a general idea on how to login and submit jobs.  Your jobs should not run in your home directory.  They should instead be in the /lustre directory.  You should first make a subdirectory in this with your username (mkdir is the command). Running simulations should be in organized directories.  So think of some naming scheme for simulations. Before starting a simulation, you will need to make a slight change to you .cshrc file in your home directory.  Using the program pico or vm type the following when you are in your home directory:
-**pico .cshrc.mine**
-At the end of the file add the following line:
-**unset noclobber**
-This is needed for the simulations to allow for files to write over existing files.
-One more recent change is that you will need to allow me to look into your /lustre files.  After you've made the directory (described above), you will need to allow access to the files by typing and replacing username with yours:
-**cd /lustre/username**
-**chmod a+r .**
-**chmod -R a+r * **
-**find . -type d -exec chmod a+x {} \;**
