[ini file:file not found]
|
|
The Open MPI OpenIB BTL component was unable to find or read an INI
|
|
file that was requested via the btl_openib_hca_param_files MCA
|
|
parameter. Please check this file and/or modify the
|

btl_openib_hca_param_files MCA parameter:

[ini file:not in a section]
|
|
In parsing Open IB BTL parameter file, values were found that were not
|
|
in a valid INI section. These values will be ignored. Please
|
|
re-check this file:

[ini file:unexpected token]
|
|
In parsing Open IB BTL parameter file, unexpected tokens were found
|
|
(this may cause significant portions of the INI file to be ignored).

In parsing Open IB BTL parameter file, unexpected tokens were found

[no hca params found]
|
|
WARNING: No HCA parameters were found for the HCA that Open MPI
|
|
detected:
|
|
|
|
Hostname: %s
|
|
HCA vendor ID: 0x%04x
|
|
HCA vendor part ID: %d
|
|
|
|
Default HCA parameters will be used, which may result in lower
|
|
performance. You can edit any of the files specified by the
|
|
btl_openib_hca_param_files MCA parameter to set values for your HCA.
|
|
|
|
NOTE: You can turn off this warning by setting the MCA parameter
|
|
btl_openib_warn_no_hca_params_found to 0.
|
|
[btl_openib:retry-exceeded]
|
|
The InfiniBand retry count between two MPI processes has been
|
|
exceeded. "Retry count" is defined in the InfiniBand spec 1.2
|
|
(section 12.7.38):
|
|
|
|
The total number of times that the sender wishes the receiver to
|
|
retry timeout, packet sequence, etc. errors before posting a
|
|
completion error.
|
|
|
|
This error typically means that there is something awry within the
|
|
InfiniBand fabric itself. You should note the hosts on which this
|
|
error has occurred; it has been observed that rebooting or removing a
|
|
particular host from the job can sometimes resolve this issue.
|
|
|
|
Two MCA parameters can be used to control Open MPI's behavior with
|
|
respect to the retry count:
|
|
|
|
* btl_openib_ib_retry_count - The number of times the sender will
|
|
attempt to retry (defaulted to 7, the maximum value).
|
|
|
|
* btl_openib_ib_timeout - The local ACK timeout parameter (defaulted
|
|
to 10). The actual timeout value used is calculated as:
|
|
|
|
4.096 microseconds * (2^btl_openib_ib_timeout)
|
|
|
|
See the InfiniBand spec 1.2 (section 12.7.34) for more details.

[no active ports found]
|
|
WARNING: There is at least on IB HCA found on host '%s', but there is
|
|
no active ports detected. This is most certainly not what you wanted.
|
|
Check your cables and SM configuration.
|
|
[error in hca init]
|
|
WARNING: There were errors during IB HCA initialization on host '%s'.
|
|
[default subnet prefix]
|
|
WARNING: There are more than one active ports on host '%s', but the
|
|
default subnet GID prefix was detected on more than one of these
|
|
ports. If these ports are connected to different physical IB
|
|
networks, this configuration will fail in Open MPI. This version of
|
|
Open MPI requires that every physically separate IB subnet that is
|
|
used between connected MPI processes must have different subnet ID
|
|
values.
|
|
|
|
Please see this FAQ entry for more details:

http://www.open-mpi.org/faq/?category=openfabrics#ofa-default-subnet-gid
|
|
|
|
NOTE: You can turn off this warning by setting the MCA parameter
|
|
btl_openib_warn_default_gid_prefix to 0.
