Asynchronous parallel I/O programming framework method under heterogeneous many-core architecture

Abstract

The invention discloses an asynchronous parallel I / O programming framework method under a heterogeneous many-core architecture. The method comprises the following steps: registering an operation coreagent writing file function in a control core function; asynchronously calling an operation core function in the control core function; when the operation core function executes the work, judging whether the last file writing of the operation core is completed or not, and if the file writing is completed, sending a file writing interrupt signal to the control core by the operation core; if the file writing is not completed, enabling the operation core to send a file writing interrupt signal to the control core by taking the to-be-executed file writing content as a parameter; when the control core executes work, if a file writing interrupt signal sent by the operation core is received, reserving the current working state, and executing the proxy file writing function to achieve the asynchronous proxy function of the control core on the operation core writing file. The operation core notifies the control core to complete the asynchronous proxy file writing function in a signal sending mode, so the execution efficiency of the control core is improved.

Description

technical field [0001] The invention belongs to the technical field of heterogeneous many-cores, in particular to an asynchronous parallel I / O programming framework method under the architecture of heterogeneous many-cores. Background technique [0002] Heterogeneous many-core is a special kind of chip, which is often equipped with a fully functional computing control core and a simplified computing core. The two cores have different instruction sets and different storage levels. When high-performance computing applications perform computing tasks, the computing core often needs to record the intermediate running results of the program by writing files at runtime for later analysis. However, when designing and implementing a heterogeneous many-core architecture, the computing core usually More consideration is given to how to speed up the operation efficiency of user programs, but less consideration is given to the support of file read and write functions, so it is difficult...
