libcppa - Designing an Actor Semantic for C++11 | Dominik Charousset
; Thomas C. Schmidt
; | Date: |
4 Jan 2013 | Abstract: | Parallel hardware makes concurrency mandatory for efficient program
execution. However, writing concurrent software is both challenging and
error-prone. C++11 provides standard facilities for multiprogramming, such as
atomic operations with acquire/release semantics and RAII mutex locking, but
these primitives remain too low-level. Using them both correctly and
efficiently still requires expert knowledge and hand-crafting. The actor model
replaces implicit communication by sharing with an explicit message passing
mechanism. It applies to concurrency as well as distribution, and a lightweight
actor model implementation that schedules all actors in a properly
pre-dimensioned thread pool can outperform equivalent thread-based
applications. However, the actor model did not enter the domain of native
programming languages yet besides vendor-specific island solutions. With the
open source library libcppa, we want to combine the ability to build reliable
and distributed systems provided by the actor model with the performance and
resource-efficiency of C++11. | Source: | arXiv, 1301.0748 | Services: | Forum | Review | PDF | Favorites |
