Hi All,
I have written a simple ring program that seems to run fine but I get
the following warning even though I am not explicitly defining the
btl_openib_ib_max_inline_data with an MCA parm. I'm only getting the
warning in the 3 machines that have the QLE7240, the other 40+ machines
with Mellanox cards give no such warning.
--------------------------------------------------------------------------
WARNING: The btl_openib_ib_max_inline_data MCA parameter was used to
specify how much inline data should be used, but a device
reduced this
value. This is not an error; it simply means that your run will use
a smaller inline data value than was requested.
Local host: fs2.calvin.edu
Local device: ipath0
Requested value: 128
Value used by device: 0
--------------------------------------------------------------------------
When I do set the value btl_openib_ib_max_inline_data = 0 in
/usr/local/etc/openmpi-mca-params.conf I get a different warning about
the setting being "deprecated"
A deprecated MCA parameter value was specified in an MCA parameter
file. Deprecated MCA parameters should be avoided; they may
disappear
in future releases.
Deprecated parameter: btl_openib_ib_max_inline_data
Is there any way I can get rid of these warnings and/or work with these
settings to optimize performance.
As always any help would be greatly appreciated.
Gary
