Outline

• Lattice introduction
• Methods
• Software
• Work to date
• Grid Sp(2$N$) integration
• DiRAC technical assessment
• H100 benchmarking
• Ongoing work
• Grid BSM benchmarks
• Continuous benchmark

Summary

• Lattice
• Has a wide software ecosystem
• Requires a lot of resources
• We have
• Integrated changes for Sp(2$N$) into Grid
• Assessed code performance on problems of interest
• Found H100+SXM+NVLink much faster thann H100 PCIe
• We will
• Develop a SOMBRERO-like benchmark in Grid
• Continue to optimise Grid Sp(2$N$) performance
• Upgrade SOMBRERO to support CUDA, explore SYCL
• Use more robust infrastructure for continuous benchmarking
