Being personally involved in the activities of the CoreGRID Institute on
Resource Management and Scheduling, I felt privileged by the possibilities
in collaborating with so many excellent partners. The continuous interest
inresearchcollaborationsleadtofruitfulandencouragingdiscussions. This
demonstratesthatCoreGRIDachieveditsgoaltoformavividandsustainable
EuropeanNetworkofExcellence.
One outcome of these collaborations is the organization of this workshop
and this seminar, and eventually the creation of this book. The proceedings

TheERCIMCoreGRIDworkinggroupincludesalargenumberofEuropean
scientistsworkingtoachievehigh-levelresearchobjectivesinGridandPeer-

established researchers from more than forty European institutions active in
thefieldsofdistributedsystemsandmiddleware,models,algorithms,toolsand
environments.
