ARC 15.03 update 9

Description

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 update includes a minor update of ARC to version 5.1.3. In addition to several bug fixes this release introduces two auxiliary tools to (a) generate backtraces from core dumps generated by ARC and (b) to convert delegation DBs between BDB and SQLite. Additionally, all ARC services kan now be managed through the systemd system, as required by the newest Fedora.

This changes the following component versions:

See the release notes for details.

QCG-Computing 4.0.0

Description

QCG-Computing is an open architecture implementation of SOAP Web service for multi-user access and policy-based job control routines by various queuing and batch systems managing local computational resources. This key service in QosCosGrid is using Distributed Resource Management Application API (DRMAA) to communicate with the underlying queuing systems. QCG-Computing has been designed to support a variety of plugins and modules for external communication as well as to handle a large number of concurrent requests from external clients and services. Consequently, it can be used and integrated with various authentication, authorization and accounting services. QCG-Computing service is compliant with the OGF HPC Basic Profile specification, which serves as a profile over Open Grid Forum standards like JSDL and OGSA Basic Execution Service. In addition, it offers remote interfaces for advance reservation management, and supports basic file transfer mechanisms. QCG-Computing was successfully tested with the following queuing systems:

Therefore, as a primary computing element of QosCosGrid stack, it can be easily set up on the majority of computing clusters and supercomputers running the aforementioned queuing systems. Currently, advance reservation capabilities in QCG-Computing are exposed for SGE, Platform LSF, Maui/Moab (a scheduler that is typically used in conjunction with Torque) and PBS Professional. Moreover, generic extensions for advance reservation have become a part of the DRMAA 2.0 standard release. Find more information on the official website.

QCG-Notification 4.0.0

Description

QCG-Notification is an open source implementation of the family of WS-Notification standards (Base Notification, Brokered Notification and Topics). It supports the topic-based publish/subscribe pattern for the asynchronous message exchange among Web Services and other involved entities. The main architecture of our system is based on a highly efficient, extended version of Notification Broker, managing all items participating in notification events. Today, QCG-Notification offers sophisticated notification capabilities, e.g. two level notification filtering, push and pull styles of notification delivery, XSLT transformations, and it was integrated with a number communication protocols as well as various security mechanisms. The modular architecture of QCG-Notification provides also a great opportunity for developers to build new extensions and plugins to meet other specific requirements. Find more information on the official website.
