[argobots-discuss] How to yield a running Xstream?

[Shintaro Iwasaki]

Hi Raghav,

xstream?
No. The official Argobots does not support this.

We wrote a research paper on preemptive context switch using ABT_thread
(i.e., automatic context switching without modifying thread's function).
This work open-sources an artifact, so you can try it for a research
purpose (but again, it is not officially supported by Argobots and not ETA
for this feature).

Thanks,
Shintaro
