What would be a place to look? Should this just be default then for
OMPI? ompi_info shows the default as 10 seconds? Is that right
'seconds' ?
The other IB guys can probably answer better than I can -- I'm not an
expert in this part of IB (or really any part I guess :). Not sure
why
a larger value isn't the default. No, its not seconds -- check the
description of the MCA parameter:
4.096 microseconds * (2^btl_openib_ib_timeout)
You sure?
ompi_info --param btl openib
MCA btl: parameter "btl_openib_ib_timeout" (current value: "10")
InfiniBand transmit timeout, in seconds
(must be >= 1)
