Scaling supercomputers comes with an increase in failure rates due to the increasing
number of hardware components. In standard practice, applications are made resilient …

As supercomputers are entering an era of massive parallelism where the frequency of faults
is increasing, the MPI standard remains distressingly vague on the consequence of failures …

Fault-tolerance has always been an important topic when it comes to running massively
parallel programs at scale. Statistically, hardware and software failures are expected to …

Future exascale systems, formed by millions of cores, will present high failure rates, and
long-running applications will need to make use of new fault tolerance techniques to ensure …

Fault-tolerance has always been an important topic when it comes to running massively
parallel programs at scale. Statistically, hardware and software failures are expected to …

Driven both by the anticipated hardware reliability constraints for exascale systems, and the
desire to use MPI in a broader application space, there is an ongoing effort to incorporate …

Most predictions of exascale machines picture billion ways parallelism, encompassing not
only millions of cores but also tens of thousands of nodes. Even considering extremely …

The resilience approach generally used in high-performance computing (HPC) relies on
coordinated checkpoint/restart, a global rollback of all the processes that are running the …

As supercomputers are entering an era of massive parallelism where the frequency of faults
is increasing, the MPI Standard remains distressingly vague on the consequence of failures …

The current system reaction to the loss of a single MPI process is to kill all the remaining
processes and restart the application from the most recent checkpoint. This approach will …
