I actually don't plan on running code without a transport (well, at least not at the moment) but being able to build it with gcc without extra flags means it can be studied and used out-of-box with IDEs. It will be great if we can eventually have a pure implementation (designed for standalone multicore systems) that works with ordinary processes/threads and shared memory. This would be great for users who want to develop Thorium applications on platforms that most of us might never use (e.g. Windows), say, using Cygwin.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Reading the rest of this thread reminded me of something. What do I need to do in order to get access to some of these nifty systems (i.e. jenny)? I also would like to be able to run Thorium programs on one of our clusters but don't think I have access to anything yet (silverclaw is just a single VM, right?) Perhaps we could give some priority to this when I come in this week. I feel a growing need to be able to run code on real systems. </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">See you on Wednesday.

I will redo the tests on jenny-mic0 since the glibc was using a lot of syscalls !<br>
