Introduction
Main entry point for usage of Aurora TSUBASA nodes is the vulcan cluster. The VH are integrated into PBSPro of the vulcan cluster, and have access to the filesystems.
Access
There are several frontend/login nodes available:
- vulcan.hww.hlrs.de
The frontend nodes are intended as single point of access to the entire cluster. Here you can set your environment, move your data, edit and compile your programs and create batch scripts. Interactive usage like run your program which leads to a high load is NOT allowed on the frontend/login nodes.
VH Access
VH access only through batch system.
Compilation
Old SX-ACE executables can not be reused. Codes have to be recompiled.
For compilation you can use the crosscompilers running on the VH nodes (not available on login nodes).
- nfort
- ncc
- nc++
- mpinfort
- mpincc
- mpinc++
VE uses elf binary format.
Execution
Standard execution model of VE is that all the executable is running on the VE card, and is therefor transfered from host to card and executed there, having access to filesystems of the host.
