APEL Client/Server 1.7.0
APEL is an accounting tool that collects accounting data from sites participating in the EGI and WLCG infrastructures as well as from sites belonging to other Grid organisations that are collaborating with EGI, including OSG, NorduGrid and INFN.
The accounting information is gathered from different sensors into a central accounting database where it is processed to generate statistical summaries that are available through the EGI/WLCG Accounting Portal.
Statistics are available for view in different detail by Users, VO Managers, Site Administrators and anonymous users according to well defined access rights.
More information on the APEL page.
- [server] Long running VM support: Cloud VMs that run over month boundaries will now have their usage in each month assigned to the correct month.
- [parsers] Added remaining job statuses for SLURM that indicate the job has stopped and that resources have been used.
- [server] Fix CpuCount being NULL in cloud accounting records and leading to warnings when summarising.
- [docs] Remove references to specific LSF versions as all now allowed.
dCache provides a system for storing and retrieving huge amounts of data, distributed among a large number of heterogeneous server nodes, under a single virtual filesystem tree with a variety of standard access methods.
Detailed release notes on the official product site: https://www.dcache.org/downloads/1.9/release-notes-3.2.shtml
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 relevant protocols (SRM, gridFTP, RFIO) for file management and access. It focus on manageability (ease of installation, configuration, low effort of maintenance), while providing all required functionality for a grid storage solution (support for multiple disk server nodes, different space types, multiple file replicas in disk pools)
The frontier-squid software package is a patched version of the standard squid http proxy cache software, pre-configured for use by the Frontier distributed database caching system. This installation is recommended for use by Frontier in the LHC CMS & ATLAS projects, and also works well with the CernVM FileSystem. Many people also use it for other applications as well
GFAL (Grid File Access Library ) is a C library providing an abstraction layer of the grid storage system complexity. The version 2 of GFAL tries to simplify at the maximum the file operations in a distributed environment. The complexity of the grid is hidden from the client side behind a simple common POSIX API.

XRootD software framework is a fully generic suite for fast, low latency and scalable data access, which can serve natively any kind of data, organized as a hierarchical filesystem-like namespace, based on the concept of directory. As a general rule, particular emphasis has been put in the quality of the core software parts.
