USE CASE 1
HPC and Cloud
OpenCUBE leverages its cloud-first infrastructure to bring its benefits to HPC applications.
OBJECTIVES
Bring solutions such as elasticity and reliability, usually seen in cloud, to HPC applications.
CHALLENGES
HPC applications are tight-coupled and traditional cloud schedulers do not take that into account.
SOLUTION
Extend the existing schedulers with methodologies proper to tight-coupled applications.
USE CASE 2
Disaggregated Memory
OpenCUBE leverages aspects of disagregated memory as a means to boost efficiency in the servers.
OBJECTIVES
Allow both HPC and Cloud applications to efficiently use disaggregated memory.
CHALLENGES
The usage of disaggregated memory currently relies on upcoming protocols or hardware, such as CXL.
SOLUTIONS
Develop software tools that can leverage disaggregated memory, such as emulator or poolers.
USE CASE 3
Workflows
OpenCUBE makes use of different applications workflows to showcase its stack, while also providing efficient resource management.
OBJECtiVES
Bring HPC workflows into cloud-first system, such as Apache Airflow.
CHALLENGES
Many applications are monolithic or do not have a proper established workflow.
SOLUTIONS
Develop such workflows with a cloud-first mentality.
USE CASE 4
Driver Workloads
OpenCUBE leverages different workloads from the HPC domain as a means to test and validate its cloud stack.
Weather forecasting
The IFS software is a major European resource representing many years of investment by ECMWF and its Member States. The IFS has been developed for over 30 years and it runs operationally, providing time-critical global forecasts several times per day.
space weather and machine learning
iPIC3D is an open-source C++ and MPI Particle-in-Cell code for the simulation of space plasma. The workflow will run iPIC3D simulation on the HPC partition with ML classification of simulation results on the cloud partition.
High-throughput molecular docking for drug discovery
AutoDock software, one of the most used software for molecular docking will be used to test on widely used databases, such as DrugBank database, Enamine database, ZINC15, and Cambridge.
