Hello,
I'm using a custom datatype created through MPI_Type_create_struct() to
send data with a dynamic structure to another process on the same node over
shared memory, and noticed it's much slower than expected.
I ran a profile, and it looks like it's not using CMA zero-copy, falling
back to us
ong as the
