Writing fast numeric algorithms for GPUs offers high application performance by offloading compute-intensive portions of the code to the GPU. The course covered basic aspects of GPU architectures and programming. Focus was on the usage of the directive-based OpenACC programming model, which allows for portable application development. Examples of increasing complexity were used to demonstrate optimization and tuning of scientific applications. Topics covered: Introduction to GPU/Parallel computing, Programming model OpenACC, Interoperability of OpenACC with GPU libraries (like cuBLAS and cuFFT) and CUDA, Multi-GPU Programming with MPI and OpenACC, Tools for debugging and profiling, Performance optimization. The course consists of lectures and interactive hands-on sessions in C or Fortran (the attendee’s choice). 000915928 536__ $$0G:(DE-HGF)POF4-5122$$a5122 - Future Computing & Big Data Systems (POF4-512)$$cPOF4-512$$fPOF IV$$x0 000915928 536__ $$0G:(DE-HGF)POF4-5111$$a5111 - Domain-Specific Simulation & Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x1 000915928 536__ $$0G:(DE-Juel-1)ATML-X-DEV$$aATML-X-DEV - ATML Accelerating Devices (ATML-X-DEV)$$cATML-X-DEV$$x2 000915928 588__ $$aDataset connected to DataCite 000915928 7001_ $$0P:(DE-Juel1)176815$$aHater, Thorsten$$b1$$ufzj 000915928 7001_ $$0P:(DE-Juel1)176293$$aHaghighi Mood, Kaveh$$b2$$ufzj 000915928 7001_ $$0P:(DE-Juel1)137023$$aKraus, Jiri$$b3$$ufzj 000915928 7001_ $$0P:(DE-Juel1)180799$$aHrywniak, Markus$$b4$$ufzj 000915928 8564_ $$uhttps://www.fz-juelich.de/en/ias/jsc/news/events/training-courses/2022/gpu-openacc-2022 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/0-aherten-overview.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/1-aherten-gpu-intro.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/2-aherten-openacc-intro.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/3-hater-debugging.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/4-hrywniak-OpenACC_Performance_Optimization.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/5-haghighi-interoperability.pdf$$yOpenAccess 000915928 8564_ $$uhttps://juser.fz-juelich.de/record/915928/files/6-kraus-Multi-GPU-Programming-with-MPI_and_OpenACC.pdf$$yOpenAccess 000915928 909CO $$ooai:juser.fz-juelich.de:915928$$pdriver$$pVDB$$popen_access$$popenaire 000915928 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145478$$aForschungszentrum Jülich$$b0$$kFZJ 000915928 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)176815$$aForschungszentrum Jülich$$b1$$kFZJ 000915928 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)176293$$aForschungszentrum Jülich$$b2$$kFZJ 000915928 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)137023$$aForschungszentrum Jülich$$b3$$kFZJ 000915928 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)180799$$aForschungszentrum Jülich$$b4$$kFZJ 000915928 9131_ $$0G:(DE-HGF)POF4-512$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5122$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vSupercomputing & Big Data Infrastructures$$x0 000915928 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5111$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x1 000915928 9141_ $$y2022 000915928 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000915928 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 000915928 980__ $$alecture 000915928 980__ $$aVDB 000915928 980__ $$aUNRESTRICTED 000915928 980__ $$aI:(DE-Juel1)JSC-20090406 000915928 9801_ $$aFullTexts
