Hey there,  
I’m trying to parallelize some code.  
The idea is to do so by dividing the data into smaller chunks and running the script on those in parallel. My question is whether it’s possible to run the same script on all nodes in a Ray cluster, however, on different data chunks.  
Sorry if it’s obvious but I’m new to Ray and would appreciate your advice!  
Thanks!
