OK. I've completely got my plan for GSoC!
1. Learn other implementations (as Antoniu said)
2. Learn Mercurium implementation
(1. and 2. would be done concurrently ;-) )
3. Implement the Mercurium `tied task' feature in libgomp/ ,
then evaluate it
4. Implement the Mercurium `untied task' feature in libgomp/ ,
then evaluate it
(4. is optional)
I'll write my proposal tomorrow (since it is 1:00 a.m. in Japan).
I'll ask you check it. If you have a time, please examine it.
Thanks,
