Grid Security Infrastructure (GSI)
The Grid Security Infrastructure (GSI), formerly called the Globus Security Infrastructure, is a specification for secret, tamper-proof, delegatable communication between software in a grid computing environment. Secure, authenticatable communication is enabled using asymmetric encryption.
Host-side Workflow
Elf/Ogrescript
Elf is a robust container designed to support scripted applications. Elf's native scripting language is Ogrescript, but it can be extended to run other kinds of scripts (e.g. Perl or Python) as well.
Previous and Existing Uses
Elf/Ogrescript is currently used along with the PWE and the Siege user interface. See Bard section above for current usage.
Planned Extensions and Modifications
The core functionality of Elf/Ogrescript should require no changes for this project. Custom Elf scripts will be developed and tested for each HPC code required for ths project as consistent with the design of Elf/Ogrescript.
