# This is the default HCA parameters file for Open MPI's OpenIB BTL.
|
|
# If HCA vendors wish to add their respective values into this file
|
|
# (that is distributed with Open MPI), please contact the Open MPI
|
|
# development team. See http://www.open-mpi.org/ for details.
|
|
|
|
# This file is in the "ini" style, meaning that it has sections
|
|
# identified section names enclosed in square brackets (e.g.,
|
|
# "[Section name]") followed by "key = value" pairs indicating values
|
|
# for a specific HCA vendor and model. HCAs are identified by their
|
|
# vendor ID and vendor part ID, which can be obtained by running the
|
|
# diagnostic utility command "ibv_devinfo". The fields "vendor_id"
|
|
# and "vendor_part"id" are the vendor ID and vendor part ID,
|
|
# respectively.
|
|
|
|
# The sections in this file only accept a few fields:
|
|
|
|
# vendor_id: a comma-delimited list of integers of HCA vendor IDs,
|
|
# expressed either in decimal or hexidecimal (e.g., "13" or "0xd").
|
|
# Individual values can be taken directly from the output of
|
|
# "ibv_devinfo". Example:
|
|
#
|
|
# vendor_id = 0x05ad
|
|
|
|
# vendor_part_id: a comma-delimited list of integers of different HCA
|
|
# models from a single vendor, expressed in either decimal or
|
|
# hexidecimal (e.g., "13" or "0xd"). Individual values can be
|
|
# obtained from the output of the "ibv_devinfo". Example:
|
|
#
|
|
# vendor_part_id = 25208,25218
|
|
|
|
# mtu: an integer indicating the maximum transfer unit (MTU) to be
|
|
# used with this HCA. The effective MTU will be the minimum of an
|
|
# HCA's MTU value and its peer HCA's MTU value. Valid values are 256,
|
|
# 512, 1024, 2048, and 4096. Example:
|
|
#
|
|
# mtu = 1024
|
|
|
|
# use_eager_rdma: an integer indicating whether RDMA should be used
|
|
# for eager messages. 0 values indicate "no" (false); non-zero values
|
|
# indicate "yes" (true). This flag should only be enabled for
|
|
# HCAs that can provide guarantees about ordering of data in memory --
|
|
# that the last byte of an incoming packet will always be written
|
|
# last. Certain cards cannot provide this guarantee (such as iWARP
|
|
# cards), while others can (such as many InfiniBand cards).
