摘要： Embodiments are disclosed for inserting profiling instructions into graphics processing unit (GPU) kernels. An example apparatus includes instructions, and at least one processor to execute the instructions to determine whether a GPU supports modification of entry point addresses, detect a first entry point address and a second entry point address of an original GPU kernel, create a corresponding instrumented GPU kernel from the original GPU kernel based on the determination by inserting at least one of first profiling initialization instructions or first jump instructions at the first entry point address of the instrumented GPU kernel, inserting at least one of second profiling initialization instructions or second jump instructions at the second entry point address of the instrumented GPU kernel, and inserting profiling measurement instructions into the instrumented GPU kernel.

摘要： Embodiments are disclosed for emulation of graphics processing unit instructions. An example apparatus includes a kernel accessor to access an instruction of an original GPU kernel, the original GPU kernel intended to be executed at a first GPU. An instruction support determiner is to determine whether execution of the instruction is supported by a second GPU different from the first GPU. An instruction modifier is to, in response to determining that the execution of the instruction is not supported by the second GPU, create an instrumented GPU kernel based on the original GPU kernel. The instrumented GPU kernel includes an emulation sequence. The emulation sequence is to, when executed by the second GPU, cause the second GPU to emulate execution of the instruction by the first GPU.

摘要： Embodiments are disclosed for emulation of graphics processing unit instructions. An example method executing an instrumented kernel using a logic circuit, the instrumented kernel including an emulation sequence; saving, in response to determination that the emulation sequence is to be executed, source data to a shared memory; setting an emulation request flag to indicate to processor circuitry separate from the logic circuit that offloaded execution of the emulation sequence is to be executed; monitoring the emulation request flag to determine whether the offloaded execution of the emulation sequence is complete; and accessing resulting data from the shared memory.

摘要： Embodiments are disclosed for inserting profiling instructions into graphics processing unit (GPU) kernels. An example apparatus includes an entry point detector to detect a first entry point address and a second entry point address of an original GPU kernel, the first entry point address including a first entry point instruction, the second entry point address including a second entry point instruction. An instruction inserter is to create a corresponding instrumented GPU kernel from the original GPU kernel by inserting first profiling initialization instructions at a first address of the instrumented GPU kernel, the instruction inserter to insert profiling measurement instructions into the instrumented GPU kernel. An entry point adjuster is to adjust a list of entry points of the instrumented GPU kernel to replace the first entry point address with the first address and the second entry point address with the second address.

An example apparatus includes an entry point detector to detect a first entry point address and a second entry point address of an original GPU kernel. An instruction inserter is to create a corresponding instrumented GPU kernel from the original GPU kernel by adding instructions of the original GPU kernel and one or more profiling instructions to the instrumented GPU kernel. The instruction inserter is to insert, at the first entry point address of the instrumented GPU kernel, a first jump instruction to jump to first profiling initialization instructions, the instruction inserter to insert, at the second entry point address of the instrumented GPU kernel, a second jump instruction to jump to second profiling initialization instructions. The instruction inserter is to insert profiling measurement instructions of the profiling instructions into the instrumented GPU kernel.
