UBITECH as technical coordinator in close collaboration with all CYBELE technical partners (i.e. BSC, BULL, CINECA, USTUTT, PSNC, RYAX, LX, ICCS, CERTH, TUT, UPRC, S5, INTRA and ENG) made available the 2nd Functional Prototypes of CYBELE Artifacts integrated within the 1st version of the CYBELE Framework. The CYBELE partners successfully integrated their software components, tools and ML models within the CYBELE Testbeds in order to deliver a holistic environment for secure experimentation composition and exploration. The experimentation composition and exploration environment (i.e. ECE) supports the configuration and execution of end-to-end Big Data and HPC analytic applications taking advantage of the convergence of hybrid Big Data-HPC workloads at the CYBELE Testbeds.
