Mike Dubman	19748e6957	fix race condition which can happen on finalize ... 1. Change in rte api implementation: now comm_world used to do p2p. This allows to not worry about other comms being destroyed. 2. added a notification mechanism with a help of which runtime can say libhcoll that RTE api can not be used any longer. pass a pointer to a flag, and its size to libhcoll. The flag changes when the RTE is no longer available. Currently this flag is just ompi_mpi_finalized global bool value. cmr=v1.7.3:reviewer=jladd This commit was SVN r29331.	2013-10-02 13:38:47 +00:00
Joshua Ladd	82e092db1b	Adding interface changes in hcoll component to support non-blocking collectives in libhcoll. This was added by Elena Elkina and reviewed by Josh Ladd. ... cmr:v1.7.3:reviewer=jladd:subject=Add support for non-blocking collectives in hcoll This commit was SVN r29244.	2013-09-25 16:14:59 +00:00
Joshua Ladd	d7a50343bf	Per the details and schedule outlined in the attached RFC, Mellanox Technologies would like to CMR the new 'coll/hcoll' component. This component enables Mellanox Technologies' latest HPC middleware offering - 'Hcoll'. 'Hcoll' is a high-performance, standalone collectives library with support for truly asynchronous, non-blocking, hierarchical collectives via hardware offload on supporting Mellanox HCAs (ConnectX-3 and above.) To build the component, libhcoll must first be installed on your system, then you must configure OMPI with the configure flag: '--with-hcoll=/path/to/libhcoll'. Subsequent to installing, you may select the 'coll/hcoll' component at runtime as you would any other coll component, e.g. '-mca coll hcoll,tuned,libnbc'. This has been reviewed by Josh Ladd and should be added to cmr:v1.7:reviewer=jladd ... This commit was SVN r28694.	2013-07-01 22:39:43 +00:00
