SciencePAD is currently in its early design and prototyping phase. Most of the functionality of this site is under development and it is not as automated or user friendly as we plan it to be for the final production version. Your contributions to the site with new registrations of users, organizations, collaborations and software, comments and new ideas are warmly welcome. For more information make sure to check the current SciencePAD Roadmap
gLExec is a program that acts as a light-weight 'gatekeeper'. it takes Grid credentials as input, and takes the local site policy into account to authenticate and authorize the credentials. It will then switch to a new execution sandbox and execute the given command as the switched identity. gLExec is also capable of functioning as a light-weight control point which offers a binary yes/no result in logging-only mode.

The LCG File catalogue (LFC) offers a hierarchical view of files to users, with a UNIX-like client interface. The LFC catalogue provides:
The Disk Pool Manager (DPM) is a lightweight storage solution for grid sites. It offers a simple way to create a disk-based grid storage element and supports both standard (HTTP/S, NFS 4.1/pNFS) and grid specific protocols (SRM, gridFTP, XROOTD, RFIO) for file management and access.
The Grid Information System provides detailed information about grid services. The Grid Information System system has a hierarchical structure of three levels. The fundamental building block used in this hierarchy is the Berkley Database Information Index (BDII). Although the BDII has additional complexity, it can be visualized as an LDAP
The Advanced Resource Connector (ARC) middleware integrates computing resources (usually, computing clusters managed by a batch system or standalone workstations) and storage facilities, making them available via a secure common Grid layer. In the past this middleware was called NorduGrid middleware, since it is being developed by the NorduGrid Collaboration. This software solution uses Grid technologies to enable sharing and federation of computing and storage resources distributed across different administrative and applica
