This paper presents the state of the art in UNICORE with respect to file transfer, and takes an in-depth look at the existing functionalities, the performance (transfer rates, reliability) and last-not-least the current limitations of the existing interfaces and available implementations. The recently introduced UFTP file transfer has been deployed and thoroughly tested in realistic environments. Here, we look at the performance of UFTP in two settings: a test installation within the PRACE infrastructure, and a 100GBit/s testbed operated by the TU Dresden and TU Freiberg. The latter study shows the potential of UFTP in a network of the highest performance. Furthermore, we present work that has been done to integrate the widely used GridFTP transfer into UNICORE, motivated by interoperability requirements in the U.S. XSEDE infrastructure as well as other European software such as dCache. Finally, we review the reliability aspects of the UNICORE server-to-server file transfer and present some possible improvements. 000129004 536__ $$0G:(DE-HGF)POF2-412$$a412 - Grid Technologies and Infrastructures (POF2-412)$$cPOF2-412$$fPOF II$$x0 000129004 7001_ $$0P:(DE-Juel1)132232$$aRambadt, Michael$$b1 000129004 7001_ $$0P:(DE-Juel1)132123$$aHagemeier, Björn$$b2 000129004 773__ $$p89-94 000129004 909CO $$ooai:juser.fz-juelich.de:129004$$pVDB 000129004 9141_ $$y2012 000129004 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132261$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000129004 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132232$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000129004 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132123$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000129004 9132_ $$0G:(DE-HGF)POF3-519H$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data $$vAddenda$$x0 000129004 9131_ $$0G:(DE-HGF)POF2-412$$1G:(DE-HGF)POF2-410$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lSupercomputing$$vGrid Technologies and Infrastructures$$x0 000129004 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 000129004 980__ $$aVDB 000129004 980__ $$aUNRESTRICTED 000129004 980__ $$aI:(DE-Juel1)JSC-20090406 000129004 980__ $$acontrib 000129004 980__ $$acontb
