New Desktop Grid on duty by Joint Institute for Nuclear Research

Desktopgrid Federation - 6 June 2013 - 10:36am

We are glad to announce that the Joint Insitute for Nuclear Research (JINR, Dubna, Russia) has successfully deployed and integrated into their existing distributed e-Infrastructure a new institutional Desktop Grid.

The recently deployed testbed is based on the SZTAKI BOINC package and is to collect underloaded computational capacities of the personal computers at JINR and its member state organisations. Thanks to the bridging technology offered by IDGF, the capacities of the formerly deployed distributed EMI (European Middleware Initative) based infrastructure has been extended and now it became able to feed the new Desktop Grid with jobs submitted by the researchers from Russia and other member states.

The deployment work has been managed by Nikolay Kutovskiy from JINR-LIT and has been supported by the SZTAKI DesktopGrid team in the frame of IDGF-SP project. More information can be found at https://gridedu.jinr.ru/DesktopGridTestbed

Renewed Statistics function

gUSE SF - 31 May 2013 - 4:12pm

The recently released gUSE/WS-PGRADE portal version 3.5.7’s main feature is the optimization of the statistics function to speed up the loading and to relive the database and the portal in overall.

Since version 3.4.1 gUSE/WS-PGRADE portals are capable to provide a very useful functionality for the users: the collection and visualization of usage statistics or shortly the statistics function. This function is responsible for collecting and storing metrics in the database and for the display of these metrics. The statistics function allows viewing metrics in four tabs – portal, DCI, user, and workflow –, on seven levels – portal, user, DCI, resource, concrete workflow, workflow instance and abstract job. This is accomplished by allowing users to navigate to different pages to see the level of statistics they want. This solution is helpful for administrator in resource settings (mainly from portal and DCI statistics) for users in middleware, resource selecting and in job execution time estimation (mainly from user and workflow statistics).

The gUSE Development Team decided that the gUSE system’s load caused by the statistics function should be reduced with a system background development. Thus, from version 3.5.7 the fast statistical data processing and providing mechanism loads the gUSE database at lower level than earlier and exploits the resources more effectively than in the previous gUSE versions.


Share and reuse workflows with a few clicks

gUSE SF - 30 May 2013 - 9:57am

Using workflows is a common point between scientists these days. However many workflow systems exist and communities develop their workflows using one of these workflow engines. Developing, testing and validating these workflows can be a very time consuming process and specific expertise is required. Reusing and sharing workflows can solve this problem.

Workflows developed for one workflow system is normally not compatible with workflows of other workflow systems. If two user communities that has similar research areas but use different workflow systems want to collaborate, they have to create the workflows from scratch to transform them to the desired workflow languages. This situation was resolved by the SHIWA project that developed the SHIWA technology to solve the workflow interoperability issue. Thanks to this new technology, publicly available workflows can be used by different research communities on different workflow systems and on multiple distributed computing infrastructures.

The SHIWA project established the SHIWA Repository that is a central store for scientists to share their workflows and browse the ones that have been already uploaded. To facilitate the needs of the communities you can upload your workflow or download the chosen workflow from the SHIWA Repository only with a few clicks through the gUSE/WS-PGRADE portal.

Through the portal one can share the workflows in native WS-PGRADE format and in IWIR format. The latter solution is useful if you want to use your workflow in a workflow system other than WS-PGRADE. In case you would like to upload your workflow in WS-PGRADE format, your workflow will not go through an IWIR conversion, just will be placed as a WS-PGRADE workflow in the SHIWA Repository.

For successful sharing, before the IWIR format conversion – but not with the WS-PGRADE format - your workflow will have to fit some rigorous preliminary conditions. (About details you can read chapter 11 of Menu-Oriented Online Help within the Portal_User_Manual.pdf document.) Thus, the shared workflows can be imported from the remote repository to the WS-PGRADE portal environment in well-known WS-PGRADE implementation format or in IWIR format at any time.

The SHIWA export-import function is available since gUSE/WS-PGRADE version 3.5.2, however it did not include the possibility to upload in native WS-PGRADE format without any conversion by that time. Since then some bug reports were filed and from the feedback received from the user communities, it was clear that it needed some improvements as well. From version 3.5.6 the usability is much improved and bugs were fixed and now it makes possible to share the workflows also in native WS-PGRADE format through the gUSE/WS-PGRADE portal.

Guide about gUSE Documentation Structure

gUSE SF - 22 May 2013 - 3:29pm

We are glad to announce that a new document is prepared for users to guide them among the different documents of gUSE.

The new guide introduces the whole gUSE documentation family organized by the target audience. :
- The green series - Manuals for administrators and operators
- The red series - Manuals for portal developers
- The blue series - Manuals for portal users
- The generic (orange) series

We recommend to start your gUSE activity by reading this document in order to better understand how gUSE documents are organized and grouped. The name of the new document is: How_To_Read_gUSE_Documents.pdf It can be found at the end of the "Files" page on the gUSE SourceForge site.

GUSE 3.5.6 is Announced

gUSE SF - 17 May 2013 - 11:32am

We are glad to announce that the version 3.5.6 of gUSE/WS-PGRADE has been released.

The main improvement in this version is the development in WS-PGRADE workflow export/import to/from Remote SHIWA Repository. From this version you can share your workflow to SHIWA project community in WS-PGRADE format and in SHIWA IWIR format as well (the latter solution is useful if you want to use your workflow by other workflow management systems than WS-PGRADE. However, for successful sharing, before in IWIR format export – unlike in WS-PGRADE format - your workflow can fit some rigorous preliminary conditions. For details see chapter 11 in Menu-Oriented Online Help of latest Portal User Manual.). Therefore the shared workflows can be imported from remote repository to WS-PGRADE portal environment in well-known WS-PGRADE implementation format or in IWIR format. (For details see chapter 7 and 11 in Menu-Oriented Online Help of latest Portal User Manual.)

Acknowledgement for MTA SZTAKI members at the newest release of OpenNebula

SZTAKI Cloud - 10 May 2013 - 1:56pm

We are proud to inform you, that MTA SZTAKI appears again in the acknowledgement section of the latest version of OpenNebula v4.0.

As you all may know, our collegues contribute to the OpenNebula develpoment more and more since the institute has started to work on the SZTAKI Cloud project. After the project members agreed that an OpenNebula based system is the best solution to achieve the amis of the project, they figured out that the solutions they give for the special scenarios can be useful in other situations as well, so they continually return these solutions to the OpenNebula team - and most of their source codes are part of the recent OpenNebula versions.

This time not only the MTA SZTAKI is listed on the acknowledgement section, but a few colleagues are mentioned by name: Márk Gergely (LPDS), Mihály Héder (ITAK) and Tamás Marlok (ITAK).

Dear guys, Congratulations on your achievements!
