While \textsf{\itshape{GuiGen}} was originally designed for the use in computational grids, it can be used in client/server environments as well. Compared to other GUI generators, \textsf{\itshape{GuiGen}} is more versatile and more portable. It can be employed in many different application domains and on different target platforms. With \textsf{\itshape{GuiGen}}, application experts (rather than computer scientists) are able to create their own individually tailored GUIs.}, language = {en} } @misc{AllalenBrehmStueben, author = {Allalen, Mohammed and Brehm, Matthias and St{\"u}ben, Hinnerk}, title = {Performance of Quantum Chromodynamics (QCD) Simulations on the SGI Altix}, issn = {1438-0064}, url = {http://nbn-resolving.de/urn:nbn:de:0297-zib-11086}, number = {08-54}, abstract = {We study performance and scaling of the Berlin Quantum Chromodynamics Program (BQCD) on the SGI Altix 4700 at Leibniz Supercomputing Centre (LRZ).
