Goal Goal

  • XWHEP aims to propose a global

XWHEP aims to propose a global computing platform by publishing its own computing platform by publishing its own resources and sharing others with resources and sharing others with different grid platforms, especially different grid platforms, especially focusing on EGEE. focusing on EGEE.

  • To achieve this goal, XWHEP :

To achieve this goal, XWHEP :

– proposes a secured DG, enabling certificate (Cert) usage, focusing on EGEE Cert. – defines different usage levels including two major ones : “public” and “private”
