Checkpointing is an I/O intensive operation increasingly used by High-Performance
Computing (HPC) applications to revisit previous intermediate datasets at scale. Unlike the …

Efficient checkpointing of distributed data structures periodically at key moments during
runtime is a recurring fundamental pattern in a large number of uses cases: fault tolerance …

While many HPC applications are known to have long runtimes, this is not always because
of single large runs: in many cases, this is due to ensembles composed of many short runs …

Abstract Reverse Time Migration (RTM) is an important scientific application for oil and gas
exploration. The 3D RTM simulation generates terabytes of intermediate data that does not …

High-Performance Computing (HPC) workloads generate large volumes of data at high-
frequency during their execution, which needs to be captured concurrently at scale. These …

Seismic imaging techniques like Reverse Time Migration (RTM) are time-consuming and
data-intensive activities in the field of geophysical exploration. The computational cost …

Parallel I/O is an effective method to optimize data movement between memory and storage
for many scientific applications. Poor performance of traditional disk-based file systems has …

In this paper, we propose an active file mode change mechanism in which the file
synchronization system of cloud storage automatically changes files in a directory of a client …

During the forward and backward modeling in Reverse Time Migration (RTM), stencil
computations constitute one of the main computationally intensive components. Their classic …

Exascale HPC systems often utilize accelerators like GPUs to accelerate entire or parts of
applications. Often, large-scale applications struggle to use the available resources fully …
