Jumping right in to an impressive start, IDSC Advanced Computing team new hire Assistant Scientist Rajesh Pasupuleti recently presented a paper at the 10th International Conference on Social Networks Analysis, Management, and Security (SNAMS-2023) in Abu Dhabi, UAE, November 21-24, 2023. (Click here for the full program.)
The paper (written with IDSC Advanced Computing Director Ravi Vadapalli and IDSC Systems and Data Engineering Director Chris Mader), entitled “Cyber Security Issues and Challenges Related to Generative AI and ChatGPT” looks at the gaining popularity of Generative AI and ChatGPT, assesses the areas of risk, and makes recommendations to secure usage. “Addressing these security issues and challenges,” Rajesh writes “requires a multi-faceted approach. It involves robust data curation and bias mitigation techniques during the model training process, implementing strong privacy and data protection measures, employing content moderation and filtering mechanisms, and continuously monitoring and updating the AI system to detect and mitigate potential vulnerabilities.” Additionally, he suggests that user education is essential, with researchers, developers, and policy makers (including CEOs, CIOs, and CSOs) working together to mitigate risks.

Fall 2023 was a busy term for Rajesh whose research areas of interest and expertise include: AI + machine learning, cyber security and threat detection analysis, business and big data analytics, grant collaborations, and research and predictive analytics. In October, he served as Technical program committee member for The International Conference on Intelligent Data Science Technologies and Applications (IDSTA2023), held in Kuwait City, Kuwait. He also served as a reviewer for Springer’s Financial Innovation journal and for the 2023 IEEE International Conference on Big Data held in Sorrento, Italy.
For IDSC, Rajesh created documentation on HPC-based container applications using Apptainer (by Singularity) and Nextflow (by Sequera) on the Pegasus supercomputer.
Apptainer is a secure, portable, and easy-to-use container system that provides absolute trust and security. It is widely used across industry and academia in many areas of work. Apptainer container applications are suitable, mostly, to fill the gap in integration between running applications on new software technologies and legacy hardware using the optimized resource utilization of CPU and memory, and can increase workflows by threefold. Apptainer was created to run complex applications on HPC clusters in a simple, portable, and reproducible way.
Nextflow is a scientific workflow system predominantly used for bioinformatic data analyses. It imposes standards on how to programmatically author a sequence of dependent compute steps and enables their execution on various high-performance and cloud computing resources. Nextflow’s scalable and reproducible workflows and allow the adaptation of pipelines written in the most common scripting languages.
Beyond these supercomputing container services provided to UM faculty and researchers, the IDSC Advanced Computing team is open to collaborations on Cyber Secuirty, Generative AI, and other emerging areas. Email us at hpc@ccs.miami.edu.
