== About Cypress ==

The Tulane University High Performance Computing system, code named “Cypress,” is one of
the fastest computers in the world. In November 2014, the TOP500 ranked Cypress as the 271st
supercomputer site in the world. It is the 3rd fastest among private American universities and
10th fastest among across all American universities.

Cypress is located in the Tulane datacenter in Downtown New Orleans. It is composed of Dell
state-of-the-art technology, using Intel Ivy Bridge CPU, Intel Xeon Phi Coprocessor, and Lustre
file system running on Dell storage with Intel Enterprise Edition for Lustre (IEEL) technology. The components of Cypress were
carefully selected to provide consistent performance over a wide range of scientific applications.
Cypress delivers a peak general capability of 369Teraflops and incorporates 11.84TB of fast
main memory with 1.476 Petabyte of parallel-distributed file system Lustre high-performance
storage, 480TB of which is dedicated to Hadoop with IEEL (Intel Enterprise Edition for Lustre)
high performance storage for use by the Hadoop data analytics queue.

== Getting an account ==

All accounts must be associated with a Tulane faculty member who is the Principal Investigator (PI) of his/her research group.  Please have your PI [[#GettinghelpContactus|contact us]] to establish a group on Cypress.  (If some members of your group have Cypress accounts, your group is already established.)  After your group is established, visit Tulane Service Now at:

https://tulane.service-now.com/

to request an account.  After logging in with your Tulane credentials, select "Order Things", then "Accounts", and finally "Cypress HPC Request" and fill out the form.
