GridwiseTech presents at 5th Cracow Grid Workshop, 20-23 Nov 2005

The Cracow Grid Workshop is organized for the fifth time to support community of researchers, developers, practitioners as well as current and potential grid users who work in the fascinating field of grid technologies and their applications. For the third time this international meeting is organised as the Central European Grid Consortium event.

During the conference GridwiseTech presents:

• LCG-API: LCG-2 and GridSphere 2.0 Integration - Jakub Dziwisz, Pawel Plaszczak
  
• LSF and SGE Interoperability Using Globus Toolkit 4 - Kuba Rozkwitalski, Chris Wilk

LCG-API: LCG-2 and GridSphere 2.0 Integration
Jakub Dziwisz, Pawel Plaszczak

For non-experts Grid portals are the only reasonable way to experience the Grid. They can provide users with the entire Grid system functionality without forcing them to hack the scripts and command line interfaces. And the more popular Grid computing is, the more important those means of access are with portals usage of cutting-edge technologies can be as easy as sending an e-mail.

LHC Computing Project (LCG) is said to be the first worldwide deployed Grid production system. It is used not only at the universities and not only by the technical gurus. Thus many of the potential users are not accustomed with terminal applications, but virtually everyone has sent a few e-mails.

Therefore it is no wonder that there is a growing demand for Grid portals compliant with LCG. To our amazement it is difficult to find a product suitable for a corporate user. Taking everything into account GridwiseTech has decided to develop their solution.

In this paper we will share our early expressions on integrating LCG-2 with GridSphere Portal, one of the most popular JSR-168 portlet containers. We will substantiate our choice of the portal solution, analyze other available LCG compliant Grid portals and examine alternative ways of integration.

Moreover we will investigate how the solution fits in GridSphere's general PortletService paradigm. We will also discuss the strengths and weaknesses of our solution, demonstrate how to "LCG-enable" simple Grid portlet and discuss the differences between "regular Grid portlet" and "LCG portlet".

LSF and SGE Interoperability Using Globus Toolkit 4
Kuba Rozkwitalski, Chris Wilk

In distributed, heterogeneous environment the interoperability between DRM solutions from different vendors is essential. Currently, the de-facto standard, Globus Toolkit 4 (GT4) is able to submit jobs to various job schedulers through its WS-GRAM component. In the sametime the GGF's DRMAA working group has been developing universal API for job management.

One of the job schedulers integrated with GT4 is Platform LSF. With GridwiseTech's compliance suite for Sun Grid Engine it is possible to submit jobs to the SGE through WS-GRAM interface.

In this paper we want to share our experiences in building truly interoperable environment for job submission to various job managers. We will present results of this integration, focusing on SGE and LSF. This will be followed by discussion on interoperability issues in job schedulers, as well as possible future directions of such integration.
