Building MOAB-TempestRemap for E3SM

Posted by in E3SM, MOAB

MOAB-TempestRemap Pre-installed MOAB comes pre-built as part of a package to test and experiment with the capabilities. This is also useful for linking against MOAB built with TempestRemap for E3SM as the build is consistent with all TPLs available with MPI enabled or disabled. For a more extensive TPL support in Conda, use the E3SM-Unified conda package. Optional Dependencies There are several...

Offline remapping workflow with mbtempest

Posted by in MOAB

For coupled climate simulations, computing accurate and conservative field remaps are critical. The MOAB unstructured mesh library with the TempestRemap remapping tool have been integrated in an effort to provide a fast, efficient and high-order accurate implementation that is scalable on large machines (refer to our manuscript in Geoscientific Model Development [1] for more details). This work...

ANL ALCF GPU Hackathon

Posted by in Hackathon, MOAB

The SIGMA team working on several MOAB mini-apps, targeted at remapping applications in climate science recently participated in a GPU hackathon and made significant progress towards exploring performance-portable implementations for remapping weight SpMV applications, and fast Kd-tree searches on both multicore and the A100 GPU architectures. Some more details are...
