ABSTRACT:
High Performance Computing is changing the way scientists make discoveries. Large scale simulations performed in supercomputers are allowing researches of all domains to better understand and study complex natural phenomena. Extreme scale computing promises great opportunities to the entire scientific community, motivating the design and development of always larger supercomputers. However, at extreme scale, component failures start compromising the usability of these systems. Multiple techniques can be used to guarantee the successful completion of the simulation, checkpoint/restart being the most popular of them. This method has been useful for several decades, but it is starting to show some limitations: while the computational power of supercomputers has been increasing exponentially, the I/O system has been growing linearly. This causes a bottleneck while writing large amounts of data to the File System. Fault Tolerance Interface (FTI) is a library that aims to provide researchers easy and scalable multilevel checkpointing.
