This is my second time going through your Ray videos, about 6mo after first watching them. I just want to say not only is this some of the most thorough and digestible Ray content I've come across, its also some of the best technical tutorial/explanation content I've come across. You have a real knack for this stuff.

Awesome video ! Can yo cover more of the high level APIs Ray offers? And things like connecting to different - hybrid - clusters ?

Hey, when I start ray on my own system it gets started and I connect another laptop using ray start -address=‘xxxxx’ -redis-password=‘xxxxxx’ The laptop gets connected to my computer but when I run heavy task only I see my computer is using 80% memory and 80% cpu while the laptop (worker) doesn’t use much cpu and memory it’s just getting connected but not using all the resources. I wonder why Do you have any idea where am I going wrong? Thanks

it is hard to say without knowing more about the specifics of the machines and code that is running. My guess is that the task might not need more resources than the computer already has (hence only 80% utilization). So Ray might be using the resources it needs only from the single computer and since it is more efficient to avoid communication over the network it never uses the "cluster"

Does a cluster have a max amount of workers it can hold?
@JonathanDinu

you can specify a maximum when you launch a cluster if you want but in theory there is no bound (or you can set this to effectively be infinite)

Hmm whats the difference between Ray and MPI? 🤔
@JonathanDinu
2 жыл бұрын
conceptually they are a little similar, but Ray has a higher level API that feels very Pythonic, has built in fault tolerance, and likely different performance characteristics for different types of jobs. From a technology standpoint, Ray is much more similar to Akka than it is to MPI.

so is it like the akka for python
@JonathanDinu

only the Actor API can be thought of as similar to Akka. The Ray project itself has many other components and is designed for ML and reinforcement learning, hence the focus on Python. So even though you could probably do similar things with Akka, they have somewhat different target audiences and use cases.
