<span class="iconify mr-1 svg-loading" data-icon="mdi:arrow-left"></span>====== Lehrveranstaltung: High-Performance Data Analytics ====== Data-driven science requires the handling of large volumes of data in a quick period of time. Executing efficient workflows is challenging for users but also for systems. This module introduces concepts, principles, tools, system architectures, techniques, and algorithms toward large-scale data analytics using distributed and parallel computing. We will investigate the state-of-the-art of processing data of workloads using solutions in High-Performance Computing and Big Data Analytics. ===== Key information ===== || Contact || [[about:people:julian_kunkel|Julian Kunkel]], [[about:people:jonathan_decker|Jonathan Decker]] || || Location || [[https://meet.gwdg.de/b/jul-35w-lfd-xfv|Virtual]] || || Time || Monday 16:15-17:45 (lecture), Monday 12:15-13:45 (lunch exercise, starts 1 week later) || || Language || English || || Module || Modul B.Inf.1712: Vertiefung Hochleistungsrechnen, Module M.Inf.1236: High-Performance Data Analytics || || SWS || 4 || || Credits || 6 || || Contact time || 56 hours || || Independent study || 124 hours || || Exam || Written date: 15.02.2024, 12-14 (Be punctual!), [[https://www.geodata.uni-goettingen.de/lageplan/?ident=2409_1_EG_0.112|Geo MN14]], 2nd exam: 28.03.2024 12-14, [[https://www.geodata.uni-goettingen.de/lageplan/?ident=2409_1_EG_0.112|Geo MN14]] || Please note that we plan to record sessions (lectures and seminar talks) with the intent of providing the recordings via BBB to other students but also to publish and link the recordings on YouTube for future terms.

In the process of learning, students will form a learning community and integrate peer learning into the practicals. Students will have opportunities to present their solutions to the challenging tasks in the class. Students will develop presentation skills and gain confidence in the topics. ===== Learning Objectives ===== * Assign big data challenges to a given use-case * Outline use-case examples for high-performance data analytics * Estimate performance and runtime for a given workload and system * Create a suitable hardware configuration to execute a given workload within a deadline * Construct suitable data models for a given use-case and discuss their pro/cons * Discuss the rationales behind the design decisions for the tools * Describe the concept of visual analytics and its potential in scientific workflows * Compare the features and architectures of NoSQL solutions to the abstract concept of a parallel file system * Appraise the requirements for designing system architectures for systems storing and processing data * Apply distributed algorithms and data structures to a given problem instance and illustrate their processing steps in pseudocode * Explain the importance of hardware characteristics when executing a given workload ===== Examination ===== Written (90 Min.) or oral (ca. 30 Min.) -> depends on the number of attendees.
