Using the NEC SX-6
The purpose of this document is to assist new users of the DKRZ
compute server during their first projects on the NEC SX-6. This
introduction is linked with other more in-depth documents on this
webserver (some of them in German) and also with the original NEC
Manuals (in English). Access to these manuals is restricted to users of
DKRZ. You can only access these manuals if you are logged in to the DKRZ web-server

Login
Usually you access the system with
ssh cross.dkrz.de
On cross you have access to all filesystems und can submit your
jobs on HLRE and track the execution.
Access to the NEC SX-6 itself is possible via
ssh
hurrikan.dkrz.de.
You can verify the hostkey's
fingerprint
here (more information on =>
ssh ).
Telnet and rlogin
are not supported for security reasons.
Interactive usage
Interactive sessions on hurrikan are restricted to avoid interference
with jobs in the queueing system. For program development and compiling
we provide a powerful cross compiler environment which allows compiling
and performance analysis of SX-6 executables on other platforms like
Linux PCs or SUN workstations. Compiling a program is much faster on
our cross compile server than on
hurrikan. This is why you
should avoid compiling interactively or, even worse, in a batch job.
