Unobtrusive Asynchronous Exception Handling with Standard Java Try/Catch Blocks

The sophisticated nature of parallel computing concepts makes parallel programming challenging. This has encouraged investigations for higher-level 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 and soundness 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 computing 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 codes, and reducing the asynchronous execution concerns in the API level. This study suggests that the concept simplifies efficient management of asynchronous exception handling concepts that appears to be challenging in parallel programming.
