Hi, all,
Is the following formatting permitted for the pe_list attribute in a
queue configuration:
...
pe_list [@hgrp1=pe_sw1],[@hgrp2=pe_sw2],[@hgrp3=pe_sw3],[@allHosts=pe_all]
...
or, perhaps
...
pe_list [@hgrp1=pe_sw1 pe_all],[@hgrp2=pe_sw2 pe_all],[@hgrp3=pe_sw3
pe_all]
...
Consider that @hgrp1 is on IB switch 1, @hgrp2 is on IB switch 2, and
@hgrp3 is on IB switch 3; that @allHosts = @hgrp1,@hgrp2,@hgrp3; that
switches 1-3 are connected to a 4th switch.
Then, we do something fun like
-pe pe* <#slots>
to get a poor man's best-effort IB topology scheduling. Would it work?
