The analysis identifies potential performance bottlenecks – in particular those concerning communication and synchronization – and offers guidance in exploring their causes. The latest Scalasca v2 release series is based on the community instrumentation and measurement infrastructure Score-P, which is jointly developed by a consortium of partners from Germany and the US. This significantly improves interoperability with other performance analysis tool suites such as Vampir and TAU due to the usage of the two common data formats CUBE4 for profiles and the Open Trace Format 2 (OTF2) for event trace data. This paper will showcase recent as well as ongoing enhancements, such as support for additional platforms (K computer, Intel Xeon Phi) and programming models (POSIX threads, MPI-3, OpenMP4), and features like the critical-path analysis. It also summarizes the steps necessary for users to migrate from Scalasca v1 to Scalasca v2. 000202902 536__ $$0G:(DE-HGF)POF3-511$$a511 - Computational Science and Mathematical Methods (POF3-511)$$cPOF3-511$$fPOF III$$x0 000202902 536__ $$0G:(DE-Juel-1)ATMLPP$$aATMLPP - ATML Parallel Performance (ATMLPP)$$cATMLPP$$x1 000202902 588__ $$aDataset connected to CrossRef Book 000202902 7001_ $$0P:(DE-Juel1)132244$$aFeld, Christian$$b1 000202902 7001_ $$0P:(DE-Juel1)132112$$aGeimer, Markus$$b2 000202902 7001_ $$0P:(DE-Juel1)132163$$aKnobloch, Michael$$b3 000202902 7001_ $$0P:(DE-Juel1)132199$$aMohr, Bernd$$b4 000202902 7001_ $$0P:(DE-Juel1)132249$$aSaviankou, Pavel$$b5 000202902 773__ $$a10.1007/978-3-319-16012-2_1 000202902 909CO $$ooai:juser.fz-juelich.de:202902$$pVDB 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)144419$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132244$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132112$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132163$$aForschungszentrum Jülich GmbH$$b3$$kFZJ 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132199$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000202902 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132249$$aForschungszentrum Jülich GmbH$$b5$$kFZJ 000202902 9131_ $$0G:(DE-HGF)POF3-511$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data$$vComputational Science and Mathematical Methods$$x0 000202902 9141_ $$y2015 000202902 920__ $$lyes 000202902 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 000202902 980__ $$acontrib 000202902 980__ $$aVDB 000202902 980__ $$aI:(DE-Juel1)JSC-20090406 000202902 980__ $$aUNRESTRICTED
