Memory Profiling and Migration for Heterogeneous Memory Architectures
Marios Asiminakis, Polydoros Petrakis, Manolis Marazakis
Heterogeneous memory systems that combine high-bandwidth memory (HBM) with commodity DRAM can accelerate bandwidth-bound HPC workloads, but current page placement largely depends o…
EPAC: The Last Dance
Filippo Mantovani, Fabio Banchelli, Pablo Vizcaino +36
This paper presents EPAC, a RISC-V-based accelerator chip developed within the European Processor Initiative (EPI) as part of a multi-year, multi-partner effort to build a European…
Running Cloud-native Workloads on HPC with High-Performance Kubernetes
Antony Chazapis, Evangelos Maliaroudakis, Fotis Nikolaidis +2
The escalating complexity of applications and services encourages a shift towards higher-level data processing pipelines that integrate both Cloud-native and HPC steps into the sam…
The ExaNeSt Prototype: Evaluation of Efficient HPC Communication Hardware in an ARM-based Multi-FPGA Rack
Manolis Ploumidis, Fabien Chaix, Nikolaos Chrysos +21
We present and evaluate the ExaNeSt Prototype, a liquid-cooled rack prototype consisting of 256 Xilinx ZU9EG MPSoCs, 4 TBytes of DRAM, 16 TBytes of SSD, and configurable interconne…
Event-Driven Testing For Edge Applications
F. Nikolaidis, A. Chazapis, M. Marazakis +1
With the rise of the Internet of Things (IoT) and Edge computing, a considerable amount of system services are moving from reliable Cloud data centers to less reliable infrastructu…
Frisbee: automated testing of Cloud-native applications in Kubernetes
Fotis Nikolaidis, Antony Chazapis, Manolis Marazakis +1
As more and more companies are migrating (or planning to migrate) from on-premise to Cloud, their focus is to find anomalies and deficits as early as possible in the development li…
Improving the Performance and Resilience of MPI Parallel Jobs with Topology and Fault-Aware Process Placement
Ioannis Vardas, Manolis Ploumidis, Manolis Marazakis
HPC systems keep growing in size to meet the ever-increasing demand for performance and computational resources. Apart from increased performance, large scale systems face two chal…
Power and Performance Analysis of Persistent Key-Value Stores
Stella Mikrou, Anastasios Papagiannis, Giorgos Saloustros +2
With the current rate of data growth, processing needs are becoming difficult to fulfill due to CPU power and energy limitations. Data serving systems and especially persistent key…
Shall numerical astrophysics step into the era of Exascale computing?
Giuliano Taffoni, Giuseppe Murante, Luca Tornatore +5
High performance computing numerical simulations are today one of the more effective instruments to implement and study new theoretical models, and they are mandatory during the pr…
