摘要

在这项工作中，我们演示了使用可移植性库将能源Exascale地球系统模型多尺度建模框架（E3SM-MMF）中使用的云解析模型（CRM）从其原始Fortran代码库移植到C++代码的过程。这个移植过程是使用另一个内核库（YAKL）执行的，YAKL是一个简化的C++可移植性库，专门用于Fortran移植。特别是，我们详细介绍了我们逐步移植大气建模系统（SAM）的方法，该系统是E3SM-MMF中使用的CRM，使用了一个混合的Fortran/C++框架，该框架允许系统复制和正确性测试逐步移植的YAKL C++代码。此外，使用OLCF的Summit超级计算机对移植代码的性能进行了分析。

SAM++: Porting the E3SM-MMF cloud resolving model using a C++ portability library

In this work, we demonstrate the process for porting the cloud resolving model (CRM) used in the Energy Exascale Earth System Model Multi-Scale Modeling Framework (E3SM-MMF) from its original Fortran code base to C++ code using a portability library. This porting process is performed using the Yet Another Kernel Library (YAKL), a simplified C++ portability library that specializes in Fortran porting. In particular, we detail our step-by-step approach for porting the System for Atmospheric Modeling (SAM), the CRM used in E3SM-MMF, using a hybrid Fortran/C++ framework that allows for systematic reproduction and correctness testing of gradually ported YAKL C++ code. Additionally, analysis is done on the performance of the ported code using OLCF’s Summit supercomputer.
