Introduction
Main entry point for usage of SX-9 system are the frontend systems
- ontake.hww.de
- yari.hww.de
Those systems can be used to compile applications for SX-9 and to submit and monitor batch jobs running on SX-9.
Compilation
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.
- sxf90
- sxcc
- sxc++
- sxmpif90
- sxmpicc
- sxmpic++
- sxar
- sxcpp
- sxmake
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.
Submission
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
