WebSep 24, 2015 · A process that uses RDMA would have an open device file connected with the ib_uverbs module. When that file descriptor is closed the module cleans up every open RDMA resource opened by the process, including any memory region and queue pair. This clean up includes notifying the HCA's driver and through it the device itself. http://www.hpdc.org/2015/program/slides/akiyama.pdf
