Abstract: A system obtains code that includes sequences of code; identifies, within a first sequence of code and based on obtaining the code, a first routine that, when executed, enables an array of values to be generated. The array of values is associated with a variable included within the first routine. The system determines whether the routine includes a particular term, and identifies, within the routine, a first identifier when the routine includes the particular term. The first identifier corresponds to a second sequence of code that identifies a first data structure that stores information that identifies one or more second routines. The system identifies, within the data structure, a second routine based on the particular term and a second identifier corresponding to the first routine; executes, using the variable, the second routine to generate a result; and outputs the result based on executing the second routine.

Abstract: A device receives a command to initiate parallel processing. The command includes an indication of a function that is to be performed in connection with the parallel processing, and a reference to a multidimensional array to which the function is to be applied. The multidimensional array includes at least three dimensions. The command also includes an indication of one or more dimensions by which the multidimensional array is to be partitioned. The device partitions the multidimensional array, along the one or more dimensions, to divide the multidimensional array into multiple blocks, each of the multiple blocks representing a subset of the multidimensional array. The device controls application of the function to the multiple blocks to cause the function to be applied in parallel to at least two blocks of the multiple blocks.

Abstract: A device may identify a first compiled block with an original constraint and an additional constraint. The first compiled block may be identified based on a program counter value and may include compiled information relating to a first segment of program code, linking information associated with a second compiled block, and information distinguishing the original constraint from the additional constraint. The original constraint may relate to a type of variable used in the first segment of programming code. The additional constraint may relate to a variable used in a second segment of programming code associated with the second compiled block. The device may copy information of the first compiled block to generate a third compiled block that lacks the additional constraint. The device may execute the third compiled block to execute a program associated with the programming code.

Abstract: A method of dynamically analyzing source code for generating usage hints while editing the source code is disclosed. A parse tree data structure is generated for each function called. The incoming and outgoing arguments in the parse tree are identified. A user calls the function by entering arguments as part of the function-call. The user's input arguments are associated with the corresponding argument in the parse tree. Relevant preconditions and post-conditions of the nodes surrounding the current location in the parse tree are analyzed to provide usage hints for the completion of the function call. In the case of a completed function call argument entered by the user, the type and number of arguments in the completed function call are compared to the required type and number of arguments of the function to validate the function call. Error messages are provided in the event of an invalid call.

Abstract: A device may receive a model including a group of blocks, and may receive a command to execute the model. The device may assign a parameter sample time to a subset of blocks of the group of blocks. The parameter sample time may permit a block, of the subset of blocks, to be executed based on a parameter change event detected during the execution of the model. The device may cause the model to be executed after assigning the parameter sample time to the subset of blocks. The device may detect a parameter change event, associated with the model, prior to the execution of the model being completed. The parameter change event may include an event that is external to the execution of the model. The device may cause at least one block, of the subset of blocks, to be executed based on the detecting the parameter change event.

Abstract: A method of ensuring the integrity of read-only components in deployed mixed-mode applications that includes generating a digital fingerprint prior to the deployment of a mixed-mode application is discussed. The digital fingerprint is based on a read-only component in the mixed-mode application and uniquely identifies the read-only component. The method also deploys the mixed-mode application and the digital fingerprint. Additionally, the method verifies, at execution time by using the digital fingerprint, that the read-only component in the mixed-mode deployed application that served as the basis for the digital fingerprint is identical to the same read-only component originally packaged with the mixed-mode application.

Abstract: A device receives program code, and receives size/type information associated with inputs to the program code. The device determines, prior to execution of the program code and based on the input size/type information, a portion of the program code that is executable by a graphical processing unit (GPU), and determines, prior to execution of the program code and based on the input size/type information, a portion of the program code that is executable by a central processing unit (CPU). The device compiles the GPU-executable portion of the program code to create a compiled GPU-executable portion of the program code, and compiles the CPU-executable portion of the program code to create a compiled CPU-executable portion of the program code. The device provides, to the GPU for execution, the compiled GPU-executable portion of the program code, and provides, to the CPU for execution, the compiled CPU-executable portion of the program code.
