As artificial intelligence continues to move from experimentation to large-scale deployment, organizations across industries face a recurring challenge: AI solutions that perform well in pilot environments often fail when exposed to real-world production demands. These failures rarely stem from model design alone. Instead, they emerge from overlooked hardware-level constraints, system interactions, and verification gaps that surface only at scale.
Senior CPU Verification Engineer Santosh Appachu Devanira Poovaiah has emerged as a prominent technical voice addressing this challenge through a growing portfolio of invited and competitively selected speaking engagements at major global conferences. Through these forums, he is educating engineers, architects, and technical leaders on why AI scalability must be engineered holistically from silicon and memory systems to software and operating system behavior.
Educating the Community on Why AI PoCs Fail in Production
At DevFest Boston 2025, hosted by Google Developer Groups Cloud Boston, Santosh was selected from a competitive pool of applicants to deliver a session titled “Bridging Silicon and Software: Moving AI from PoCs to Production at the Hardware Level.” The flagship event, held in Cambridge, Massachusetts, drew a diverse audience of engineers, researchers, and industry leaders, and opened with remarks from Google CEO Sundar Pichai, underscoring its global significance.
During the session, Santosh addressed a question facing many AI teams today: why do so many projects stall after proof of concept? He explained how performance regressions and silent correctness failures often appear only when AI workloads scale beyond laboratory conditions. Drawing on real-world system behavior, he highlighted the influence of CPU and GPU architectural interactions, cache coherency mechanisms, memory bandwidth constraints, and system-level bottlenecks that are frequently underestimated during early development.
Rather than presenting theory alone, the talk focused on actionable engineering insights. Santosh demonstrated how insufficient verification of accelerators, incomplete coherency validation, or incorrect assumptions about shared memory behavior can derail AI deployments late in the integration cycle. He introduced practical countermeasures, including hardware-aware benchmarking, workload-driven verification methodologies, and hardware–software co-design strategies aligned with production realities.
The session resonated strongly with the audience. Technical leaders gained clarity on why AI systems must be designed end-to-end, while developers and system architects gained concrete guidance on verification practices that directly impact reliability and performance at scale.
Addressing Security and Trust in Unified CPU-GPU Memory Systems
Santosh’s focus on system-level rigor extends beyond performance into security. At the Secure Software by Design 2025 event organized by the Carnegie Mellon University Software Engineering Institute in Arlington, Virginia, he delivered an invited technical talk titled “OS-Level Trust Assumptions in Shared CPU-GPU Memory Systems.” He was selected from a competitive applicant pool to address emerging security risks in unified memory architectures.
The talk examined how implicit trust assumptions between operating systems and hardware components can introduce vulnerabilities in shared CPU-GPU memory environments particularly in modern AI platforms that rely on tight coupling and high-throughput data sharing. Santosh presented verification-driven strategies to identify and mitigate OS–hardware trust boundary weaknesses before they manifest as correctness or security failures in deployed systems.
The session attracted senior engineers, security leaders, and industry professionals, including individuals recognized for their leadership in the technology sector. Its strong reception led to the talk being published on CMU SEI’s official YouTube channel [ https://www.youtube.com/watch?v=KBV3VOqtxpg&list=PLSNlEg26NNpwJUAddNUV8bucX85aXPfX4&index=16 ], reaching an audience of nearly 19,000 subscribers and reflecting sustained community interest in the topic.
Advancing AI Adoption in Semiconductor Verification
In another notable engagement, Santosh was selected to present at the Verification Futures Conference 2025, held in Austin, Texas, as part of Tessolve Semiconductor Ltd’s global conference series. His session, “Applying Generative AI in Post-Silicon Validation: Real Use Cases and Technical Insights,” was chosen through a competitive technical review process.
The presentation explored how generative AI techniques can be applied to post-silicon validation workflows, including coherency-driven stimulus generation, automated failure triage, and coverage optimization in complex System-on-Chip environments. Emphasizing practical adoption over hype, Santosh showcased how AI-assisted validation can improve efficiency and diagnostic depth while preserving the rigor required for production silicon.
The session drew strong engagement from an international audience of verification engineers, architects, and semiconductor professionals, reflecting growing industry demand for AI-enabled verification methods grounded in real engineering constraints.
Building Knowledge Through Mentorship and Community Engagement
Beyond conference stages, Santosh actively contributes to knowledge sharing and professional development within the engineering community. He serves as a mentor in a global technical mentorship program supporting top new graduates, providing advanced guidance on system-level design, verification, and scalable computing challenges. He has also acted as a judge and mentor at national innovation hackathons, including SheBuilds 2025 and the TrackShift Innovation Challenge 2025.
In addition, he has been invited to serve as a resume review panelist for the University of Southern California’s Viterbi Career Connections program, offering industry feedback to undergraduate, master’s, and PhD students preparing to enter advanced engineering roles.
A Hardware-Centric Voice for the Future of AI
As organizations increasingly demand higher performance, stronger security guarantees, and predictable scalability from AI systems, Santosh’s work highlights a critical truth: many AI failures originate not in algorithms or code, but in hardware interactions and system assumptions that surface only under real-world workloads.
Through his speaking engagements, mentorship, and technical advocacy, Santosh continues to educate the industry on the importance of end-to-end system thinking. By bridging silicon-level realities with software expectations, his work supports a more reliable transition from AI experimentation to production execution. He plans to further expand his global speaking engagements and technical outreach, continuing to guide the industry at a pivotal moment in adoption of AI.
