Quantum Espresso
Quantum Espresso
Quantum ESPRESSO is an integrated suite of Open-Source computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials.
Quantum ESPRESSO has evolved into a distribution of independent and inter-operable codes in the spirit of an open-source project. The QuantumESPRESSO distribution consists of a “historical” core set of packages and a set of plu
GridSite
GridSite
GridSite was originally a web application developed for managing and formatting the content of the GridPP website. It has further grown into a set of extensions to the Apache web server and a toolkit for Grid credentials, GACL access control lists and HTTP(S) protocol operations. In its simplest application, GridSite uses X.509 certificates loaded into unmodified versions of web browsers like Internet Explorer, Netscape or Mozilla to authenticate users, and then grant
L&B
Logging and Bookkeeping (L&B)
Logging and Bookkeeping (LB for short) is a Grid service that keeps a short-term trace of Grid jobs and other grid-related processes as they are processed by individual Grid components. The LB was initially developed in the EU DataGrid project as a part of the Workload Management System (WMS). The development continued in the EGEE project (EGEE-II, EGEE-III respectively), where LB became an independent part of the gLite middleware. Currently we are participating in the EMI project ( see LB status in EMI, gLite Logging and Bookkeeping Product Team).

LCG File Catalog (LFC)
The LCG File catalogue (LFC) offers a hierarchical view of files to users, with a UNIX-like client interface. The LFC catalogue provides:
- Logical File Name (LFN) to Storage URL (SURL) mappings (via a GUID);
- Authorisation on its logical

Disk Pool Manager (DPM)
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.
AMGA
ARDA Metadata Grid Application (AMGA)
- One of the most popular and widely used metadata catalog service in the Grid Community
- Provide and support a mechanism for locating scientific data files using descriptive information through Grid authentication
- Ensure competitive performance and scalability, along with a multi-threaded multi-process based on DB connection pooling, a hierarchical collection structure, replication and a federation mec
