[libfabric-users] Scalable Memory Registration.

[Isaac Nuñez]

Hi,

I was wondering about the flexibility of Scalable Memory Registration (for RMA operations). In the man pages for libfabric-1.9.0 (the version I am using) says that memory registration occurs in address ranges, but then what the parameter of len in fi_mr_reg implies? Can I allocate this MR dynamically? Let's say I reserve a space 256 bytes at first, but my application grows and now I need 1GB (Checkpoints), can this adapt or both must now exactly the MR size not only for the MR key but when executing the fi_read, can I read more of what was initially reserved?
