Unobtrusive Asynchronous Exception Handling with Standard Java Try/Catch Blocks

Abstract

The sophisticated nature of parallel computing concepts makes parallel programming challenging. This has encouraged higherlevel frameworks that conceal much of the complications behind abstraction layers. Paradigms in this category are mostly performance centric, and do not share the same sentiments for the robustness of asynchronous executions. This is while current applications demand consistency in addition to fast performance. Therefore, programming environments that offer high-level support for asynchronous exception handling will have higher chances for popularity. This paper discusses our latest enhancements to @PT, a parallel programming environment that is based on Java annotations. The proposed concept promotes the robustness of parallelized programs by adhering to the familiar exception handling standards of sequential code, and reducing the asynchronous execution concerns at the API level. This study suggests that the concept simplifies efficient management of asynchronous exceptions, which appears to be a challenge in parallel programming.
