Summary
Energy Sector Leverages HPC and Cloud to Meet Rising Computational Demands
In the evolving landscape of the energy sector, high-performance computing (HPC) is increasingly crucial for digital transformation, particularly in advanced seismic imaging. As computational demands skyrocket, the industry is turning to cloud solutions like AWS Energy HPC Orchestrator and NVIDIA Energy Samples to meet these challenges. “The integration of cloud-native solutions is essential for tackling complex computational tasks,” states Mark Tindale, head of HPC at a leading energy firm. These developments signify a pivotal shift toward optimising performance and cost-efficiency.
Main Article
In recent years, the energy sector has witnessed a transformative shift driven by high-performance computing (HPC) technologies, particularly in seismic imaging and reservoir simulation. These advanced methodologies, including reverse time migration (RTM) and full waveform inversion (FWI), are indispensable for generating high-resolution subsurface images, pivotal for oil and gas exploration. However, the computational load associated with these techniques has seen exponential growth. For instance, a mere doubling of the maximum frequency in seismic imaging can result in a 16-fold increase in computational demands. Similarly, halving the grid discretisation across all three dimensions in reservoir simulations can amplify computational requirements by a factor of eight.
Cloud Computing as a Solution
In response to these escalating demands, the energy industry is increasingly embracing cloud computing for its inherent scalability and flexibility. The transition to cloud-based HPC applications, however, necessitates substantial engineering efforts to modernise existing systems. This is where solutions like the AWS Energy HPC Orchestrator and NVIDIA Energy Samples become indispensable.
AWS Energy HPC Orchestrator
The AWS Energy HPC Orchestrator is an integrated platform designed to facilitate the transition of HPC applications to the cloud. Developed as a collaborative effort between AWS and leading energy companies, the platform is engineered to ensure interoperability between processing modules, thereby optimising scalability, flexibility, and economics. At its core, the Orchestrator provides a suite of pre-optimised, cloud-native HPC templates, significantly simplifying the modernisation process and fostering the creation of an open HPC marketplace.
The reference architecture of the AWS Energy HPC Orchestrator is noteworthy. It includes an orchestration system for various HPC applications, utilising a common storage system, along with enterprise functionalities for user and data management. A marketplace for distributing compatible HPC applications is another integral component. This architecture also establishes data standards to ensure seamless interoperability between diverse applications.
A unique feature of the AWS Energy HPC Orchestrator is its use of extensions—plug-ins that offer domain-specific capabilities, including implementations of algorithms like RTM or FWI. These extensions must comply with the event-based protocols defined by the core system, ensuring a cohesive operational environment.
Microservice Architecture and NVIDIA Integration
The RTM template stands out as a significant component of the AWS Energy HPC Orchestrator. This template is designed to transform traditional RTM applications into modernised, cloud-native versions, leveraging robust AWS services to enhance scalability, resilience, and operational efficiency. The RTM algorithm is executed through a dynamic backend, segmented into four distinct microservices: Analysis, Migration, Reduction, and Converter.
Each microservice is specialised for specific tasks within the RTM algorithm. For example, the Analysis Service initiates the workflow by scanning seismic files and dispatching metadata into the migration queue. Subsequently, the Migration Service loads models and processes seismic data to generate 3D images, followed by the Reduction Service, which stacks these images into a single composite image. Finally, the Converter Service formats this stacked image for output.
This microservice architecture is designed for resilience and scalability, employing a queuing system that enables autonomous scaling of each service. This design ensures optimal resource allocation and fault tolerance, allowing the system to efficiently manage varying workloads.
The integration of NVIDIA Energy Samples with the AWS Energy HPC Orchestrator further augments the platform’s capabilities. NVIDIA Energy Samples offer reference implementations of key seismic processing algorithms, optimised for NVIDIA GPUs, enabling geophysicists to develop high-performance implementations incorporating their customisations.
RTM, in particular, benefits significantly from accelerated computing powered by NVIDIA GPUs. The AWS RTM template, coded in Python, is structured into four microservices and pre-optimised for compatibility with Amazon S3. Modifications to the Migration Service enable seamless integration of NVIDIA Energy Samples with the AWS Energy HPC Orchestrator.
