I am actually thinking about sticking with one dat.conf.

For example, OFED would change to look like the following:

#

# DAT 1.2 and 2.0 configuration file

#

# Each entry should have the following fields:

#

# <ia_name> <api_version> <threadsafety> <default> <lib_path> \

#           <provider_version> <ia_params> <platform_params>

#

# For the uDAPL cma provder, specify <ia_params> as one of the following:

#       network address, network hostname, or netdev name and 0 for port

#

# Simple (OpenIB-cma) default with netdev name provided first on list

# to enable use of same dat.conf version on all nodes

#

# Add examples for multiple interfaces and IPoIB HA fail over, and bonding

#

OpenIB-cma u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2 "ib0 0" ""

OpenIB-cma-1 u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2 "ib1 0" ""

OpenIB-cma-2 u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2 "ib2 0" ""

OpenIB-cma-3 u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2 "ib3 0" ""

OpenIB-bond u1.2 nonthreadsafe default libdaplcma.so.1 dapl.1.2 "bond0 0" ""

OpenIB-2-cma u2.0 nonthreadsafe default libdaplcma.so.2 dapl.2.0 "ib0 0" ""

OpenIB-2-cma-1 u2.0 nonthreadsafe default libdaplcma.so.2 dapl.2.0 "ib1 0" ""

OpenIB-2-cma-2 u2.0 nonthreadsafe default libdaplcma.so.2 dapl.2.0 "ib2 0" ""

OpenIB-2-cma-3 u2.0 nonthreadsafe default libdaplcma.so.2 dapl.2.0 "ib3 0" ""

OpenIB-2-bond u2.0 nonthreadsafe default libdaplcma.so.2 dapl.2.0 "bond0 0" ""

Arlin,

how do two proposed way impact configuration files?

Subject: [dat-discussions] RFC: DAT 1.2 and 2.0 library build and installation

I am thinking about allowing coexistence of 1.2 and 2.0 libraries for the next release. This will insure that we continue to support 1.2 providers while new providers needing 2.0 features can also install and run on the same system. Does anyone see problems with this or have any suggestions other then separate naming conventions? I am thinking we will have to build/install 2.0 as dat2.conf, libdat2.so, libdapl2.so, and the development package as /usr/include/dat2/include.

comments?

Thanks,
