CHESS
Station Computers and Networking

Wireless Network:

CHESS is fully covered by an 11 megabits per second wireless network.  Several access point give good coverage throughout the lab.  All of the second floor and 3rd floor conference room are also well covered.  The network is protected with 64 bit encryption.  CHESS users can request the network key during their visit.  CHESS does not supply wireless network cards.  Wireless network cards must support 64 bit encryption.

Bringing a Computer to CHESS:

Users who plan to bring computers to CHESS should inform us ahead of time.  It can save a lot of user time if we are prepared to connect you to our network.  The CHESS computer group may not have time to assist you on arrival if we do not know about your computing needs.  If you plan to bring a computer to CHESS you must follow these simple guidelines:

• Notify CHESS in advance of equipment and needs.

• Windows computers which are bought from outside must have an up to date virus scanner installed.

• Users must supply administrator logins and passwords to the computer group for any computers connected to the CHESS network.

Common Questions:

Question:  Can I hook up with my laptop into the CHESS network?

Answer:  Yes, but you must have a current version antivirus program running real time file protection with the latest virus definitions.  Please contact Phil Sorensen - 607-255-2785 to arrange hookup for your laptop to the CHESS network.

Question:  Can I ftp my data from my home institution?

Answer:  The CHESS firewall is configured to allow SSH connections.  As such, you can login to the machine that has your data using its full name (computer.chess.cornell.edu), the specuser account and password.

Supercomputing at CHESS:

MacCHESS now supports two supercomputers.  Feynman features 64 dual processor nodes.  Each node is equipped with 2 gigabytes of RAM and is networked with two gigabit per second, low latency, fiber optic networking.

SIRIUS has Athlon 2400+ CPU processors.  Each node contains one gigabyte of RAM and is networked with the same high speed Myrinet networking as Feynman.  Sirius serves MacCHESS scientists as a development system.  In the event of very large jobs, Feynman and Sirius can be combined into a single machine with almost 200 CPUs.
