In this video from PASC18, Leonardo Bautista from the Barcelona Supercomputing Center presents: Easy and Efficient Multilevel Checkpointing for Extreme Scale Systems.

Extreme scale supercomputers offer thousands of computing nodes to their users to satisfy their
computing needs. As the need for massively parallel computing increases in industry, computing
centers are being forced to increase in size and to transition to new computing technologies.
While the advantage for the users is clear, such evolution imposes significant challenges, such
as energy consumption and reliability. In this talk, we will discuss how to guarantee high reliability
to high performance applications running in extreme scale supercomputers. In particular,
we cover the tools necessary to implement scalable multilevel checkpointing for tightly coupled
applications. This includes an overview of failure types and frequency in current HPC systems.
The talk will also cover the theoretical analysis necessary to achieve optimal utilization of the
computing resources. Moreover, we will discuss the internals of the FTI library tool, to study how
multilevel checkpointing is implemented today.
