Project Description

The 2025 INCITE OpenFanWing Team is collaborating with LLNL developer to transition one of the open-source libraries they will need in future INCITE cycles. The library is Zero-RK (https://github.com/LLNL/zero-rk/tree/hip). This is the hip compatible version of the library. The team is already using the library in El Capitan and in AMD machines at GE Aerospace but they want to transition it to Aurora. The suggestion was to port the library to our systems to understand how it works and evaluate paths to transition it to use ChipStar on Aurora (for that, a separate DD on Aurora will be requested). In principle, Catalyst and LLNL library developer are the expected users. It might be that another GE Aerospace collaborator would like to join but it is unclear at this time. Therefore, for the moment only 2 users.
