=========================================================================
SCREAMv1 Tutorial Information: During the E3SM All-Hands meeting, the EAMxx development team will conduct a one-day SCREAMv1 tutorial. EAMxx (and its km-scale configuration called SCREAM) represents a complete overhaul of the existing E3SM Atmosphere Model, developed from scratch in C++ utilizing the Kokkos performance portability library. The tutorial will introduce participants to the EAMxx software infrastructure, covering essential topics such as running E3SM with EAMxx, incorporating new parameterizations, and developing and executing unit tests. We will conclude with an “advanced topics” session focusing on strategies for parallelism and memory management within EAMxx.
This tutorial is aimed at anyone interested in running or modifying EAMxx as well as developers seeking a deeper understanding of EAMxx design choices to inform their own component development. Please note that seating is limited to 40 participants, so register early if you are interested.

Prerequisites
Participants are encouraged to familiarize themselves with the following topics. See the provided links for helpful information.
Familiarity with CIME case management system. User guide available here.
Some familiarity with C++ programming. There are plenty of online resources (e.g., cplusplus, learncpp, geeksforgeeks, etc.)
Basic understanding of HPC architectures, including concepts like CPU, GPU, threads, memory, and parallelism. Wikipedia can be a good place to get some knowledge (e.g. see pages for CPU, GPU, threads, memory, parallel processing, MPI, and pages linked within those)
Familiarity with CMake. You can find a good intro here (particularly the basics and testing). Or you can go straight to the source.
