Hi @hkaiser,

I’m interested in contributing to HPX for GSoC and found this issue intriguing. I have been learning HPX and parallel computing, and I would like to work on implementing P2079 for the system execution context. Could you provide some guidance on where to start and any specific areas I should focus on?

Looking forward to your suggestions.

Well first of all you will have to look into sender/receivers in order to understand the context. Then, looking into HPX and how we integrated S&R with it, would be the next step.

hello @hkaiser I’m planning to implement P2079 by creating hpx::parallel_scheduler to wrap hpx::threads, with a schedule() returning a sender, tying into HPX’s sender/receiver model. Does that sound good?

For tests, should I start fresh or extend existing ones? Any specific scheduler code I should look at? Thanks!

@charan-003 Here are the currently existing schedulers:

For tests, should I start fresh or extend existing ones?

I'd leave that up to you.
