Gamma 3.3 and OFED 1.2 DAPL Release

June 2007

DAPL GAMMA 3.3/OFED 1.2 RELEASE NOTES

This release of the DAPL reference implementation

is timed to coincide with OFED release 1.2 of the

Open Fabrics (www.openfabrics.org) software stack.

NEW SINCE Gamma 3.2 and OFED 1.1

* New Features

1. Added dtest and dapltest to the openfabrics build and utils rpm.

Includes manpages.

2. Added following enviroment variables to configure connection management

timers (default settings) for larger clusters:

DAPL_CM_ARP_TIMEOUT_MS 4000

DAPL_CM_ARP_RETRY_COUNT 15

DAPL_CM_ROUTE_TIMEOUT_MS 4000

DAPL_CM_ROUTE_RETRY_COUNT 15

* Bug Fixes

+ Added support for new ib verbs client register event. No extra

processing required at the uDAPL level.

+ Fix some issues supporting create qp without recv cq handle or

recv qp resources. IB verbs assume a recv_cq handle and uDAPL

dapl_ep_create assumes there is always recv_sge resources specified.

+ Fix some timeout and long disconnect delay issues discovered during

scale-out testing. Added support to retry rdma_cm address and route

resolution with configuration options. Provide a disconnect call

when receiving the disconnect request to guarantee a disconnect reply

and event on the remote side. The rdma_disconnect was not being called

from dat_ep_disconnect() as a result of the state changing

to DISCONNECTED in the event callback.

+ Changes to support exchanging and validation of the device

responder_resources and the initiator_depth during conn establishment

+ Fix some build issues with dapltest on 32 bit arch, and on ia64 SUSE arch

+ Add support for multiple IB devices to dat.conf to support IPoIB HA failover

+ Fix atomic operation build problem with ia64 and RHEL5.

+ Add support to return local and remote port information with dat_ep_query

+ Cleanup RPM specfile for the dapl package, move to 1.2-1 release.
