Course convener: David Vicente

Lecturers: David Vicente, Javier Bartolomé, Carlos Tripiana, Oscar Hernandez, Rubén Ramos, Félix Ramos, Pablo Ródenas, Jorge Rodríguez, Marta Renato, Cristian Morales

Objectives: The objective of this course is to present to potential users the new configuration of MareNostrum and a introduction on how to use the new system (batch system, compilers, hardware, MPI, etc).Also It will provide an introduction about RES and PRACE infrastructures and how to get access to the supercomputing resources available.

Learning Outcomes: The students who finish this course will know the internal architecture of the new MareNostrum, how it works, the ways to get access to this infrastructure and also some information about optimization techniques for its architecture.

Level: INTERMEDIATE -for trainees with some theoretical and practical knowledge; those who finished the beginners course.

Prerequisites:  Any potential user of a HPC infrastructure will be welcome
