Experience
HPC Cluster Patching and Upgrade
The project involved systematically patching and upgrading the software stack, including the operating system, middleware, and HPC-specific applications, to ensure optimal performance and compliance with industry standards.
AI/ML Job Prediction
Cluster Consolidation
I designed the architecture of the consolidated clusters based on the assessed requirements, considering factors such as workload distribution, fault tolerance, scalability, and resource allocation. Next, I deployed the new cluster infrastructure according to the designed architecture, covering hardware setup, software installation, configuration, and testing.
