New release for uDAPL 2.0 available on the OFA download page and in my git tree.
New UCM provider uses it's own CM protocol on top of IB-UD queue pairs. During device open, this provider creates a UD queue pair and returns local address information via dat_ia_query. This 24 byte opaque address must be exchange out-of-band before connecting to a server via dat_ep_connect. This provider is targeted for MPI implementations that already exchange address information during boot/init phase and offers better scaling then existing scm and cma providers. md5sum: 9a8be3e780a6105fb4d9c85dacf556af dapl-2.0.22.tar.gz Summary of changes for last 2 releases: 2.0.22 v2 - ucm: new provider using DAPL based IB-UD cm mechanism for MPI v2 - dapltest: add processor yield when polling for completions 2.0.21 v2 - scm: Fix disconnect. QP's need to move to ERROR state in v2 - dtest: modify dtest.c to cleanup CNO wait code and consolidate into v2 - common: CNO events, once triggered will not be returned during the cno wait. v2 - scm, cma: CNO support broken in both CMA and SCM providers. v2 - common osd: include winsock2.h for IPv6 definitions. v2 - common osd: include w2tcpip.h for sockaddr_in6 definitions. v2 - DAPL introduced the concept of directly waiting on the CQ for v2 - dapltest: Implement a malloc() threshold for the completion reaping. v2 - scm: handle connected state when freeing CM objects v2 - scm, dtest: changes for winof gettimeofday and FD_SETSIZE settings. v2 - scm: set TCP_NODELAY sockopt on the server side for sends. v2 - windows: remove obsolete files in dapl/udapl source tree v2 - dtestcm: add UD type QP option to test v2 - scm: destroy QP called before disconnect v2 - cma: add support for rdma_cm TIME_WAIT event. v2 - scm: remove old udapl_scm code replaced by openib_scm. v2 - winof: fix build issues after consolidating cma, scm code base. v2 - cma: lock held when exiting as a result of a rdma_create_event_channel failurb v2 - windows: all dlist functions have been moved to the header file. v2 - dtestcm windows: add build infrastructure for new dtestcm test suite v2 - openib_common: reorganize provider code base to share common mem, cq, qp, dto v2 - scm: fixes and optimizations for connection scaling v2 - scm: double the default fd_set_size v2 - scm: EP reference in CR should be cleared during ep_destroy v2 - dtestx: fix conn establishment event checking v2 - dtestcm: new test to measure dapl connection rates.
