Zhejiang University Team Claims Global Championship at IndySCC Supercomputing Competition

In a remarkable display of talent and tenacity, the supercomputing team from Zhejiang University (ZJU) has clinched the global championship at the IndySCC Student Supercomputing Competition. This victory, announced recently, marks the second time ZJU has claimed the top honor in this prestigious event, solidifying their position as a powerhouse in student-led high-performance computing (HPC) challenges. 72 71 The win comes after an intense 46-hour cloud-based showdown where the team optimized limited virtual resources to outperform competitors from leading universities worldwide, including rivals from Peking University and Tsinghua University.

The IndySCC competition, tied to the renowned SC supercomputing conference series, emphasizes education and inclusion, making it accessible to emerging talents through its remote format. ZJU's success highlights the growing prowess of Chinese universities in fostering HPC expertise among undergraduates from diverse majors, from computer science to English and business analytics. This achievement not only boosts national pride but also underscores the role of such competitions in preparing students for cutting-edge careers in research and technology.

Decoding the IndySCC: Supercomputing for the Next Generation

The IndySCC, or Indy Student Cluster Competition, is a fully remote, cloud-based event designed as a companion to the more hardware-intensive Student Cluster Competition (SCC) held at the annual SC conference. Unlike the SCC, which requires teams to assemble physical clusters, IndySCC levels the playing field by providing standardized virtual machines (VMs)—typically a handful like five H100 GPU nodes—in a cloud environment. Teams have just 46 hours to tackle a series of computationally demanding benchmarks and applications, simulating real-world HPC pressures. 72

Key challenges include:

• HPL (High-Performance Linpack) benchmark: Measures raw floating-point performance through dense linear algebra computations, requiring optimizations like parallel partitioning and BLAS library tuning.
• Climate simulation (Exascale Climate Emulator - ECE): GPU-heavy modeling of Earth's climate systems to predict environmental changes.
• System simulation (Structural Simulation Toolkit - SST): CPU-focused emulation of large-scale computing architectures.
• High-energy physics tasks: Including particle tracking and reconstruction.
• Mystery problem: A surprise challenge, such as ACTS (A Common Tracking Software) for high-energy physics event reconstruction, demanding rapid adaptation.

Success hinges on endurance, strategic scheduling, bottleneck identification, and no-idle resource utilization, often monitored via live dashboards. ZJU's team excelled by achieving perfect scores on multiple tasks and maximizing output on the mystery challenge until the submission deadline. 71

ZJU Supercomputing Team: A Multidisciplinary Powerhouse

Established in 2014, ZJU's supercomputing team recruits undergraduates across disciplines, fostering a 'mentoring chain' where veterans guide newcomers. The latest championship squad featured:

• Li Chenxiao (team leader, Computer Science undergraduate, Class of 2026): Orchestrated scheduling and mystery task execution.
• Mao Jinyuan (sophomore, Business Big Data Analytics): Handled SST, proactively fixing organizer material gaps.
• Hong Yixun (second-year, Information Security): Emphasized methodical code debugging.
• Li Hourong (second-year English major): Contributed to ECE, embodying the team's 'stay hungry, stay foolish' ethos.
• Others like Jiang Yize and Hao Xingxing from prior iterations highlight the team's continuity.

Advisors such as Associate Professor Wang Zeke integrate coursework, labs, and weekly meetings, promoting knowledge sharing over siloed expertise. This approach yielded over 50 awards, including multiple ASC first prizes and ISC top-5 finishes. 71

For students eyeing HPC careers, ZJU's model offers actionable insights: join cross-major teams, prioritize hands-on practice, and embrace evidence-driven problem-solving. Explore opportunities at research jobs or higher ed jobs to launch your path.

The 46-Hour Marathon: Strategies Behind ZJU's Triumph

From kickoff at 9 a.m. U.S. time to 7 a.m. submission, ZJU adopted a 'no-idle' strategy: reserving GPUs for heavy tasks like ECE and ACTS, threading SST on CPUs, and trial-running on weak nodes first. They manually compiled dependencies, iterated fixes amid sparse docs, and maximized data points on mystery tasks. Live dashboards ensured 100% utilization, with uploads hitting full just in time.

Li Chenxiao noted, 'It wasn’t just about solving problems; it was about scheduling.' This blend of tactics, stamina, and feedback—like Mao's organizer corrections—secured the crown against global elites. 72
