Summary, in English

LCG and ARC are two of the major production-ready Grid middleware solutions being

used by hundreds of HEP researchers every day. Even though the middlewares are based

on same technology, there are substantial architectural and implementational

divergencies. An ordinary user faces difficulties trying to cross the boundaries of

the two systems: ARC clients so far have not been capable accessing LCG resources and

vice versa. After presenting the similarities and differences of the LCG and ARC

middlewares, we will focus on the strategies implementing interoperable layers over

the two middlewares. The most important areas are the job submission and management

and information system components. The basic requirement for the interoperability

layer implementation is capability of transparent cross Grid job submission both from

ARC and LCG.
