APEL Client/Server 1.8.1

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.

Release notes:

  • [client] Added option to update benchmarks/spec levels using a local configuration option rather than the BDII.

APEL-SSM 2.4.0

Secure STOMP Messenger (SSM) is designed to simply send messages using the STOMP protocol or via the ARGO Messaging Service (AMS). Messages are signed and may be encrypted during transit. Persistent queues should be used to guarantee delivery.

SSM is written in Python. Packages are available for RHEL 6 and 7, and Ubuntu Trusty.

The installation and configuration guide is available here: https://github.com/apel/ssm

Check also the EGI wiki for more information about APEL SSM.

Release notes:

  • Added support for sending and receiving messages using the ARGO Messaging Service (AMS).
  • Added option to send messages from a directory without needing to conform to the file naming convention that the dirq module requires.
  • Fixed SSM hanging if certificate is not authorised with the broker. Now it will try other brokers if available and then correctly shut down.
  • Fixed an OpenSSL 1.1 syntax error by including missing argument to checkend.

ARC 6.1.0

The Advanced Resource Connector (ARC) middleware is an Open Source software solution to enable distributed computing infrastructures with the emphasis on processing large volumes of data. ARC provides an abstraction layer over computational resources, complete with input and output data movement functionalities. The security model of ARC is identical to that of Grid solutions, relying on delegation of user credentials and the concept of Virtual Organisations. ARC also provides client tools, as well as API in C++, Python and Java.

Release notes

This is a bugfix release, mainly to address a problem causing job failures in certain circumstances. In addition some build fixes are included related to openssl 1.1.1 and python, new ARCHERY endpoint types are added to the endpoint retrieval plugin and monitor, and a fix related to GLUE2 is included.

NorduGrid ARC 15.03 has received an update to:

  • core, clients, CE, Infosys and gridftp - from version 5.4.3 to 5.4.4
  • documents - from 2.0.20 to 2.0.21

Gangliarc, Nagios plugins and metapackages are unchanged. .

davix 0.7.4

davix is a C++ toolkit for advanced I/O on remote resources with HTTP based protocols.

Release notes:

dCache 4.2.40

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-4.2.shtml

DMLite/DPM 1.13.1

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)

N.B. starting from this version, the gridftp and http frontends are build together with the dpm core, so they have new package names

  • lcgdm-dav -> dmlite-apache-httpd
  • dpm-dsi -> dmlite-dpm-dsi

as well as the xrootd frontend starting from v 1.12: dpm-xrootd -> dmlite-dpm-xrootd

Dynafed 1.5.0

The Dynamic Federations system allows to expose via HTTP and WebDAV a very fast dynamic name space, built on the fly by merging and caching (in memory) metadata items taken from a number of (remote) endpoints. More information.

gfal2 2.16.3

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.
