Hi all, Following question can be of naïve nature. Kindly, help me to clarify the points. Thanks in Advance.
Consider an application on top of uverbs / udapl library and wants to use only rdma write operations. While using RDMA write operations, one has to indicate the responder side(receiving side) somehow that the data transfer is complete. This can be achieved simply by doing an extra rdma write (sort of control write) conveying successful completion of DTO. Instead of this, can programmer poll/check on the last data (int or byte) assuming in-order placement of data in the receive buffer. Can such behavior of last byte written last, assumed ? If application programmer can rely on such behavior, then this asks for all networks to guarantee such behavior. It will be helpful if some information is shared as how mvapich2 handles the situation regarding above point (while using rdma operations) ? I thought that i should mail to both the mailing lists as topic covers both domains.
