Abstract: A method for executing a plurality of data-parallel threads of a processing logic on a processor core includes grouping the plurality of data-parallel threads into one or more workgroups, associating a first workgroup from the one or more workgroups with an operating system thread on the processor core, and configuring threads from the first workgroup as user-level threads within the operating system thread. In an example, a method enables the execution of GPU-kernels that has been previously configured for a GPU, to execute on a CPU such as a multi-core CPU. The mapping of the numerous data-parallel threads to the CPU is done in such a manner as to reduce the number of costly operating system threads instantiated on the CPU, and to enable efficient debugging.

Abstract: A linker is described and the method of forming an executable program from object code modules using the linker. The linker uses a linker control language in the form of an ordered sequence of relaxation instructions. The relaxation instructions include a jump relaxation instruction which specifies the instruction count of the relaxation instruction which is subsequently read. In this way, more flexibility can be provided for linkers.

Abstract: A method of forming an executable program from a plurality of object code modules, each object code module comprising section data and relaxation instructions, at least one of said object code modules comprising a library module of predefined section data and relaxation instructions, the executable program to be run on a target processor having a selected endianness, the method comprising in response to a relaxation instruction, loading a library module into temporary storage; retrieving the value of a first variable, said first variable denoting the selected endianness of the target processor; comparing the value of said first variable with the endianness of the section data and relaxation instructions of the library module; in response to the result of the comparing step not being a match, converting the endianness of the section data of the library module to that of said first variable; processing the relaxation instructions and converted section data to form part of the executable program.
