Computer-implemented method, computer-readable medium and heterogeneous computing system

Abstract

A computer-implemented method includes initializing a first processing unit (71) of a heterogeneous computing system with a first compute kernel (140-144) and a second processing unit (72) of the heterogeneous computing system with a second compute kernel (150-154). Both the first compute kernel (140-144) and the second compute kernel (150- 54) are configured to perform a numerical operation derived from a program segment (220) configured to receive a first data structure (A) storing multiple elements of a common data type. The program segment (220) includes a function meta information including data related to a size of an output of the numerical operation, a structure of the output, and / or an effort for generating the output. The function meta information and a data meta information of aruntime instance (A1) of the first data structure (A) are used to determine first expected costs of executing the first kernel (140-144) on the first processing unit (71) to perform the numerical operation with the runtime instance (A1) and to determine second expected costs of executing the second kernel (150-154) on the second processing unit (72) to perform the numerical operation with the runtime instance (A1). The data meta information includes at least one of a runtime size information of the runtime instance (A1), a runtime location information of the runtime instance (A1), a runtime synchronization information of the runtime instance (A1) and a runtime type information of the runtime instance (A1). The method further includes one of executing the first compute kernel (140-144) onthe first processing unit (71) to perform the numerical operation on the runtime instance (A1) if the first expected costs are lower than or equal to the second expected costs, and executing the second compute kernel (150-154) on the second processing unit (72) to perform the numerical operation on the runtime instance (A1) if the first expected costs are higher than the second expected costs.

Description

technical field [0001] The present invention relates generally to a feedthrough element, and more particularly to an improved feedthrough element capable of being used in harsh environments with high operating or emergency temperature above 260°C. Specifically, the feedthrough elements of the present invention can withstand operational and / or emergency pressures of 42,000 psi. They can therefore be used in various applications, notably in downhole drilling equipment and for the safe containment of toxic substances and in aircraft. Background technique [0002] The efficient utilization of heterogeneous computing resources is extremely demanding, especially in the field of numerical and data analysis. This involves the task of parallelizing programs, which is often tedious, expensive, and requires knowledge of low-level computer architecture and programming techniques associated with parallelizing programs. [0003] Historically, the starting point for solving this problem ...
