Objectives & realization
Methods
Virtual Lab AMsterdam
• Enable VLAM-G users to define, execute, and
monitor their experiments
• Provide to VLAM-G users:
location independent experimentation,
familiar experimentation environment
assistance during their experiments
Easy way to bring/port new/existing applications to
the Grid
•Developing
and to learn
application prototypes to check ideas

Process Flow Template
(PFT)
•
Used as a blueprint for a specific type of
experiments
•
PFT is designed offline by the experts in each
scientific domain
•
It is the main interface used by the VLAM-G
users to perform a specific experimentation in
the VLAM-G environment.
•
It Guides the user while performing the
experiment.

Status of the VLAM-G
Prototype
•
The first Beta-release is almost ready
•
This release will contain:

A tool to load modules in the VLAM-G database

A list of modules that can selected and used

C/C++ API to write VLAM-G modules

Support for the MACS and DNA array
experiments

It should be conform to the Globus security

It is going to be running on DAS-2
