Mar 1, 2025March 2025 performance summary for gismo/gismo. Focused on stabilizing the build, expanding domain modeling capabilities, and reducing technical debt to accelerate future delivery. Key features delivered - Domain API: Added domain() accessor to gsComposedBasis, delegating to the underlying basis (commit 22b3656e9525184285b7282ad749bd023d62ddc1). This improves API usability and reduces boilerplate for domain retrieval. - New Expression Classes in G+Smo: Added a broad suite of expression classes (abs_expr, add_expr, adjugate_expr, asdiag_expr, colBlocks_expr, colsum_expr, constMat_expr, curl_expr, diag_expr, divide_expr, exp_expr, flat_expr, frprod_expr, grad_expr, idMat_expr, lapl_expr, max_expr, mult_expr, nabla2_expr, nabla_expr, normal_expr, onormal_expr, pow_expr, ppart_expr, ppartval_expr, replicate_expr, reshape_expr, rowsum_expr, sign_expr, sub_expr, tangent_expr, temp_expr, trace_expr, transpos...) to extend expression evaluation capabilities in G+Smo (commit a0069ebb9b25ca8ac1710c70d9c0c3874f5dcd2b). Major bugs fixed - Bug Fix: Correct include path to resolve compiler error in gsComposedBasis by updating the include to gsDomain/gsDomainIterator.h (commit 1947aed77ba6cf991a9167456f70ad5c96083116). Codebase improvements and impact - Codebase Refactor and Cleanup: Substantial internal reorganization—header cleanup, macro standardization, removal of legacy code, and quadrature/tests cleanup across multiple commits (b5f5956a5b644dc58030efd2a58e2e7dc7651273; 393ee06b7aa4491f2e9b1c390c2cb2304066dcbf; e994f7beab3802787d4925aff2f08ab989b9884f; 1ce61d1a34ba041c2e7d1afbf6f26a7ff6e8c427; 5cdd86529df40add5d59e25c9c899182c795b82f; fb25323eb1e60e4769544ff00703e36bf8171005; af9f66ba95a353eac08b6ef9560ba0fda2eeab30). This reduces debt, improves maintainability, and stabilizes builds across modules. - Test infrastructure: Added a temporary test file to support ongoing quality checks (commit fb25323eb1e60e4769544ff00703e36bf8171005). Technologies/skills demonstrated - C++ header management and include-path resolution; API design; large-scale refactor and cleanup; expanded DSL/expression evaluation capabilities; test scaffolding. Business value - Faster, more reliable feature delivery; improved maintainability; enhanced modeling capabilities enabling customers to build richer domain simulations with less risk.
