Compiler systems and methods that solve the DAE transformation problem by simulating DAEs using general-purpose compilers are disclosed herein. The compiler systems and methods extend an existing general-purpose intermediate representation (IR) with a minimal set of intrinsics to represent the model function, which allows leveraging existing compiler technology. A first compiler input is a model of a physical system from source modeling languages. A second compiler input is a first IR for each subroutine specific to the model. The model is compiled to a second IR that is universal across multiple source modeling languages. The IR maps each primitive of the source modeling language to a subroutine call specific to the source modeling language from which the primitive is derived. The first and second IRs are combined into a third IR that describes the model in terms of intrinsics of the third IR.

A structured query language (SQL) query including an SQL intrinsic function is processed using native code including single instruction multiple data (SIMD) or single instruction multiple thread (SIMT) processor instructions for execution on a processor having native parallelism. The native code is compiled from an implementation of the SQL intrinsic function in a platform-independent source code. The compiling comprises compiling the source code to generate a platform-independent intermediate representation (IR) of the source code. The IR is optimized for improved performance through parallelization. The optimized IR is lowered to generate the native code.

This invention relates to the field of SIMD technology on the Shenwei platform, and particularly to a method for implementing SIMD intrinsics based on the Shenwei platform. The method includes the following steps: S1: Scan the source code to determine if there are x86 intrinsic functions; S2: Determine if the x86 intrinsic functions can be reconstructed on the Shenwei platform; S3: Reconstruct the x86 intrinsic functions; S4: Perform testing; Test the x86 intrinsic functions reconstructed on the Shenwei platform in step S3 using libjpeg test cases. If the test results on the Shenwei platform are consistent with the test results on the x86 platform, it proves that the SIMD intrinsic functions on the Shenwei platform and the x86 intrinsic functions have the same functionality. This method can achieve x86 intrinsic compatibility at the source code level.
