UNICORE Description

An open source ready-to-run Grid system including client and server software UNICORE (Uniform Interface to Computing Resources) makes distributed computing and data resources available in a seamless and secure way in intranets and the internet.UNICORE is a modern, WS-RF and Web services based, OGSA-compliant, ready-to-run, standards-conform, Grid technology implemented in Java. UNICORE makes distributed computing, data, networkUNICORE has special characteristics that make it unique among Grid middleware systems. The UNICORE design is based on several guiding principles, that serve as key objectives for further enhancements. Here are some key features of "UNICORE": · Abstraction: UNICORE users need not know details about the system that they use. UNICORE provides abstractions for concepts such as application software and storage locations. Thus, UNICORE allows seamless access to heterogenous environments. · Security: UNICORE offers strong security based on industry standards such as the X.509 PKI. Communication over the internet is protected by mutual authentication. · Site autonomy: when making resources available on the Grid, administrators keep fine-grained control about their resources. Local policies are respected. · Ease of use: A powerful GUI client covers the most common usage scenarios, such as application execution and multi-step, multi-site workflows. · Ease of installation: UNICORE is simple to install, with minimal external dependencies. Quickstart bundles exist that allow to get up-and-running quickly. Requirements: · Java 5 or later · Perl 5 or later What's New in This Release: General: · make update.sh script sh-compatible (fixes errors on Ubuntu) · GUI installer fixes (wrong IDB on Windows, removed files that are not needed) · add install.py helper that copies only the necessary files to the · installation directory (sf bug 2184302) · smarter component start/stop scripts: wait for server shutdown, · avoid accidentally starting multiple times, better stop order in · top-level stop.sh · included UDT C++ source code in the udt-src folder · Windows IDB includes .bat file execution "CMD shell" Gateway: · improved connection logging (peer address, peer DN) and · error logging (sf feature 2038886) · allow to disable the detailed site listing (sf feature 2807790) · site details show connection error details in addition to the "sad monkey" · forward VSite HTTP errors to the client when doing HTTP PUT UNICORE/X: · fix proxy generation from DSA keys (sf bug 2545056) · refactored XNJS storage handling. This makes it much easier to integrate · new storage backends · CIP info provider is published to registry (sf feature 2788384) · fix import to storage root dir, which caused a "chmod 0600" (sf bug 2808523) · fix bug when filetransfer instances could not be destroyed · new Apache Hadoop integration module (experimental) · improved map-file authoriser · new TSI parameter TSI_PROCESSORS_PER_NODE and TSI_TOTAL_PROCESSORS · (with obvious semantics). Existing TSI_PROCESSORS is kept. · simplified UDT module (no longer needs the 'empty' utility) · fix message signing verification problems when using p12 keystore · and separate truststore (by using latest WSS4J) · destroying a file transfer will now cancel the running transfer TSI: · fix PutFiles.pm to handle paths containing spaces · improved ExecuteScript.pm · new TSI_TOTAL_PROCESSORS and TSI_PROCESSORS_PER_NODE variables Registry: · access control on the Registry (sf feature 2807780). · See registry/conf/uas.config for more information · individual entries can be deleted (using e.g. "ucc wsrf destroy") · but only if access control is enabled XUUDB: · fix duplicate xlogin when running the admin.sh add command twice · (sf bug 2797971) · allow overwriting CSV file when exporting (sf feature 2779253) · "admin.sh list" prints XUUDB info (server version, DN/normal mode) · (sf feature 2797975) · fix DN format used in "update" command (sf bug 2803417) · do not allow "adddn" command if not in DN mode (sf bug 2807632)
