What is the maximum number of entries in the lookup table (numEntries)? What does this parameter affect? What are the boundaries of his assignment? How to choose this number correctly?

Hi Michael,

SharedRegion.numEntries defines the number of shared regions in the system. You can set this to however many shared regions you need, but increasing it will reduce the maximum size of each region.

See and for more information on SharedRegions.

I did not understand the purpose of this parameter. Why divide into entries? Can I write to a specific Entry? How to understand how many shared regions do I need? are there any criteria for choosing the number of shared regions?

Hi Michael,

It depends on your application and system. You may want multiple SharedRegions defined for different regions of memory, and you may want them to be cacheable or non-cacheable. Or you may want different cores owning each SharedRegion. In any case, this option gives you that flexibility.
