After Compilers and Operating Systems : The Third Advance in Application Support
share
After compilers and operating systems, TSIAs are the third advance in application support. A compiler supports a high level application definition in a programming language. An operating system supports a high level interface to the resources used by an application execution. A Task System and Item Architecture (TSIA) provides an application with a transparent reliable, distributed, heterogeneous, adaptive, dynamic, real-time, interactive, parallel, secure or other execution. In addition to supporting the application execution, a TSIA also supports the application definition. This run-time support for the definition is complementary to the compile-time support of a compiler. For example, this allows a language similar to Fortran or C to deliver features promised by functional computing. While many TSIAs exist, they previously have not been recognized as such and have served only a particular type of application. Existing TSIAs and other projects demonstrate that TSIAs are feasible for most applications. As the next paradigm for application support, the TSIA simplifies and unifies existing computing practice and research. By solving many outstanding problems, the TSIA opens many, many new opportunities for computing.
