A new release of the MOAB library (v5.5.0) is now available. The tarball can be downloaded here. If you are working with release branches in Bitbucket, please use the newly created “5.5.0” tag to get the latest changes.Some notable updates:– New support for the calculation of scalable, bilinear maps with TempestRemap for Climate problems– Removed: Mesquite sources and...
Read MoreFor 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...
Read MoreMOAB Pre-installed MOAB comes pre-built in several different flavors and can be directly installed on several supported platforms. Docker image: Conda: Optional Dependencies There are several option dependencies for MOAB. Features and tools get automatically built based on the enabled dependencies when configuring MOAB library. MPI: MOAB supports usage of MPICH and OpenMPI libraries configured...

Read MoreThe 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...
