Does IJobProcessComponentData run in parallel?

Hey all, I had a quick question about

IJobProcessComponentData

. I've seen spurious documentation claiming that

IJobProcessComponentData

runs in parallel similar to

IJobParallelFor

. I'm trying to understand how

IJobProcessComponentData

determines the batch size. If it sets the batch size to

1

then wouldn't that be less efficient than using

IJobParallel

and setting the batch size to something like

32

,

64

,

128

, etc.?

Thanks in advance!

 

If I am not wrong it goes parallel per chunk

 

So it processes 16k of data per core at a time I guess?

 

Yes, if the chunk is full. I never really looked into the source or read a detailed explanation, my understanding is that it is just an abstraction layer of IJobChunk (i.e. the inner loop)

 

Oh I see, so it's going to process some number of entities based on the archetype size but the amount of data depends on which components you're actually accessing. Thanks very much for the clarification!
