Present: Liwei, Roland, Steve, Lucas, Cheng-Hsin, Yosef, Allen, Helvi, Swapnil, Zach, Erik
Liwei
- Optimized the subcycling implementation in CarpetX, acchieving better performance compared to Carpet
Roland
- Working on adding a Z4c test
Lucas
- Tuning the parameter within the hybrid RK integrator to achieve larger CFL factors (7x faster already compared to the traditional RK method)
- Trying to evolve BBH simulations on Multipatch grids using CanudaX
- PR on NewRadX is almost ready
Cheng-Hsin
- Successfully compiled CanudaX on Bridges-2, which features V100 GPUs. Next steps include testing and profiling its performance
- Based on the tests on Delta, CanudaX is slightly faster then Z4c, but still comparable (~1.5 M/h on 1 GPU node, with qc0).
Jay
- Installing Fuka on Frontier to test the optimized subcycling implementation with BNS simulations
Swapnil
- A colleague is interested in porting their nucleosynthesis code to CarpetX
Zach
- BHaHAHA is working with ETK, doing some final performance and accuracy tests
Steve
- Progress on generating BSSN with NRPy+ for CarpetX
Erik
- Investigating an issue where the compiler struggles with accessing grid functions using foo(p.I), particularly when an object file is provided.
