Are there languages that support threads?

    Currently, Ada, Modula-3, Python 1.4, SmallTalk/X, Objective-C/ Gnustep and Java have intrinsic language elements to support threads (for example, Ada has the 'Select' statement which is a "thread guard"). However, the Linux implementations of these languages do not yet support the new kernel threads.

    Naturally, C and C++ can make calls to spawn threads and processes, but there are no language elements to support them beyond these system calls. See below for a listing of available languages:

Threading Languages

Titles: Ada/Ed

Newsgroup: comp.lang.ada [news:comp.lang.ada]
Threads Lib: LinuxThreads
Description: Ada/Ed is a translator-interpreter for Ada. It is intended as a teaching tool and does not have the capacity, performance or robustness of commercial Ada compilers. Ada/Ed was developed as a long-range project in language definition and software prototyping.
License: GPL

Title: Guavac & Kaffe (Java)
Author: ???
Repositories: Guavac Documentation [http://http.cs.berkeley.edu/~engberg/guavac/]

Kaffe Source [ftp://ftp.sarc.city.ac.uk/pub/kaffe/]

Newsgroup:
Threads Lib: ???
Description: Guavac is a new compiler for the Java language, written by Effective Edge Technologies and distributed under the Gnu Public License. You should feel free to use, copy and modify it, based on the terms in the COPYING file included in this distribution.

Kaffe is a virtual machine design to execute Java bytecode. Unlike other virtual machines available, this machine performs "just-in-time" code conversion from the abstract code to the host machine's native code. This will ultimately allow execution of Java code at the same speed as standard compiled code but while maintaining the advantages and flexibility of code independence.
