just::thread C++0x Thread Library V1.3 Released

Wednesday, 13 January 2010

I am pleased to announce that version 1.3 of just::thread, our C++0x Thread Library has just been released.

This release is the first to feature support for the new std::async function for starting asynchronous tasks. This provides a higher-level interface for managing threads than is available with std::thread, and allows your code to easily take advantage of the available hardware concurrency without excessive oversubscription.

This is also the first release to support 64-bit Windows.

The linux port is available for 32-bit and 64-bit Ubuntu linux, and takes full advantage of the C++0x support available from g++ 4.3 and g++ 4.4. The Windows port is available for Microsoft Visual Studio 2008 for both 32-bit and 64-bit Windows. Purchase your copy and get started NOW.

As usual, existing customers are entitled to a free upgrade to V1.3 from all earlier versions.

Happy New Year 2010

Tuesday, 05 January 2010

It's already five days into 2010, but I'd like to wish you all a Happy New Year!

2009 was a good year for me. Back in January 2009, my implementation of the C++0x thread library went on sale, and sales have been growing steadily since — there's a new version due out any day now, with support for the new std::async functions and 64-bit Windows. I also presented at the ACCU conference for the second year running and completed the first draft of my book.

It's also been a big year for the C++ community. The biggest change is of course that "Concepts" were taken out of the C++0x draft since they were not ready. On the concurrency front, the proposal for the new std::async functions was accepted, std::unique_future was renamed to just std::future and the destructor of std::thread was changed to call std::terminate rather than detach if the thread has not been joined or detached.

Popular articles

As is my custom, here's a list of the 10 most popular articles and blog entries from the Just Software Solutions website in 2009. The key difference from last year's list is the rise of the C++0x thread library stuff.

What's coming in 2010?

Will 2010 be even better than 2009? I hope so. There's a new version of just::thread coming soon, and there's another ballot on the C++0x working draft due in the spring. I'll also be presenting at ACCU 2010 in April.

What are you looking forward to in 2010?
