Accessing the System
Main entry point for usage of SX-9 system are the frontend systems
Those systems can be used to compile applications for SX-9 and to submit and monitor batch jobs running on SX-9.
The only way to access the NEC SX-9 (frontend systems) from outside HWW net is through ssh.
Information on how to set up ssh can be found on our webserver at Secure Shell (ssh).
Only for "yari.hww.de" there also exists a second access method using a X.509 enabled ssh service.
Information on how to set up X.509 enabled ssh can be found on our webserver at X.509-SSH.
You should recompile applications for SX-9, as well as SX-8 binaries will run. But recompilation will end in higher execution speed.
For compilation you can use the crosscompilers, they are prefixed with sx.
Linked libraries are found in /SX in the frontends, but that searchpath is implicit, and has not to be specified. But make sure your Makefiles do not include -I /usr/include, that ends in wrong header included in C programs.
For details of batch jobs see Batch system, the most used commands to manipulate jobs are
- qsub for submission
- qstat for monitoring
- qs for site specific monitoring (you see all jobs, not only yours)
- qdel for aborting a job
- qalter to change an existing job
- qcat to see output of a running job
