IntegralSpecification -> C++SourceCode
Compile symbolic molecular integral recurrence relations (such as Obara-Saika) into highly unrolled, SIMD-friendly C++ code for specific angular momenta.
Problem it solves
Manual implementation of molecular integrals for high angular momenta is error-prone and lacks optimal processor instruction scheduling.
