Orchestrating Multimodal RAG With Agentic Workflows With OpenSearch - Bobby Mohammed & Surya Kari, Amazon Web Services

Tuesday June 3, 2025 11:15am - 11:35am IST

Ceres

Retrieval-Augmented Generation (RAG) has emerged as a powerful paradigm for grounding large language models (LLMs) in external knowledge, enabling more accurate and contextually relevant responses. However, traditional RAG pipelines often operate in a static, pre-defined manner, limiting their ability to adapt to complex queries and dynamically explore information spaces. This talk introduces "Multimodal Agentic RAG", an innovative approach that integrates autonomous agents into the RAG framework to enhance its reasoning and retrieval capabilities. This talk will delve into the architecture and implementation of multimodal RAG with agentic workflows, showcasing its potential to address limitations of traditional RAG. The architecture is based on OpenSearch's multimodal capabilities, DeepSeek-R1's reasoning capabilities, and custom-tuned embedding models. Furthermore, we will discuss the challenges and future directions of Agentic RAG, including the development of robust planning mechanisms, efficient knowledge source management, and effective agent coordination.

Operational Logs and Event Management for HPC Systems Using OpenSearch: Alerting and Dashboards - Sinchana Karnik, Raghul Vasudevan & Ambresh Gupta, Hewlett Packard Enterprise

Tuesday June 3, 2025 12:00pm - 12:40pm IST

Ceres

HPCM (HPE Performance Cluster Manager) is a suite for monitoring HPC systems, consisting of rack, chassis, compute nodes(GPU, CPU), power,cooling components. OpenSearch, deployed in a distributed manner, enables efficient indexing and querying of large volumes of data. For real-time monitoring, events across the system is collected and streamed to Kafka, then persisted in OpenSearch via Logstash, allowing for efficient log management. OpenSearch Dashboards, integrated with Fluent Bit, provide real-time log observability, enabling users to visualize and analyze system logs for insightful cluster monitoring. We have developed a user-friendly wrapper around OpenSearch Alerting that uses custom YAML-based configurations to define alerting rules, categorize alerts by severity and group, and trigger notifications to endpoints like email,alertmanager. Argonne National Laboratory's Aurora, the third-fastest supercomputer in the world, uses 21,248 CPUs and 63,744 GPUs across 166 racks. HPCM, along with its 10-instance OpenSearch database deployed on 10 nodes, successfully manages and monitors events and logs, with OpenSearch Alerting effectively deployed to track critical system issues.

Observability in a Airgapped High Performance Computing Environment - Adinarayana Haridas, IBM

Tuesday June 3, 2025 1:40pm - 2:00pm IST

Jupiter

In high-performance computing (HPC) environments, the need for robust observability mechanisms is critical to ensure optimal performance, fault tolerance, and resource utilization. Airgapped systems, often used in sensitive or high-security domains, require innovative solutions to capture, analyze, and visualize system metrics, application performance, and infrastructure health without compromising security.

Challenges arise in airgapped HPC environments, where network isolation adds complexity to monitoring and diagnostics. I explore methodologies for establishing observability in airgapped HPC environments, focusing on the unique challenges of data collection, real-time monitoring, and offline analytics. Additionally, I discuss the role of automated anomaly detection, resource optimization, and performance tuning in maintaining the efficiency and reliability of these systems. The findings highlight the importance of maintaining a balance between high security and comprehensive observability, paving the way for more resilient and performant airgapped HPC environments.

Integrating Graph Context With OpenSearch for Enhanced RAG Application Performance - Satej Sahu, Zalando SE

Tuesday June 3, 2025 3:35pm - 4:15pm IST

Grand Ballroom 1

OpenSearch is a powerful tool for log storage, analysis, and dashboard reporting. In the context of Retrieval-Augmented Generation (RAG) applications with Large Language Models (LLMs), OpenSearch serves as a vital component, acting as a vector database. This presentation explores an architecture and process flow to integrate graph-based context with OpenSearch, enhancing the correlatability of data and improving the context and performance of search results.

Through experimentation with synthetic data from a travel app, we’ll demonstrate how customer activity data—such as travel points, preferences, and interactions with destinations—can be integrated into OpenSearch. By introducing graph points and correlating them with other data (e.g., maps and historical data), we can provide personalized, more relevant search results for users. Additionally, we’ll compare metrics before and after the introduction of graph context to showcase how it improves search performance and the overall user experience in RAG-based systems.
