Changes

Haas research computing for PhD students currently consists of '''bear''' and '''phd-pgsql'''. This pages details these resources.

==Bear==

There are three ways of using bear:

===Storing Data on Bear===

You can use a copy of PuTTy to SSH onto bear. PuTTY is a free SSH client that you can [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html download from its author]. You don not need to 'install' it - it is a standalone executable file. [http://groups.haas.berkeley.edu/hcs/howdoi/install_putty.pdf Details for the configuration] are available from the [http://groups.haas.berkeley.edu/HCS/howdoi.html howdoi section] of the haas website, but none is really needed.

The address to connect to bear is:

bear.haas.berkeley.edu

And the connection is on the standard port (22). You can set your username under:

Connection -> Data -> Auto-login Username

And save the connection settings if you want.

If you are running scripts then you should use the ''bsub'' to have them execute on the compute nodes, rather than the login node, as otherwise a runaway script can bring the entire of bear to a stand still. An example syntax for running a perl script is:

bsub -Is "perl Script.pl"

Available scripting languages include:

*Python

*R

There are also (apparently - I haven't tested them) compilers for:

*C++ (GNU Cpp)

*Fortran 77

To see your files you might want the following simple commands:

*'''cd bulk''' - change into the bulk directory

*'''cd ..''' - change up a directory

===Using Xwindow Applications on Bear===

Remember - Bear is your R drive, so the root of bear, when you login, is the root of your R drive!

==PhD-PGSQL==

'''phd-pgsql''' is a new and experimental database server for PhD students and faculty. It hosts a cope of PostgreSQL with support for R, Perl and C++ scripting inside of the RDMS. At present the server is being deployed. More news will be available here shortly!
