Hi Frank, Ian, Everyone<br>
<br>
Yes, I meant doing this via Simfactory. But at the same time I
acknowledge the fact that it could as well be doable via some Cactus
parameter... On that note, we have tried changing the parameter in
the top-level SIMFACTORY directory under the job directory. However,
looking at the parfile in the new checkpoint directory, it still
bore the old value. We even went as far as changing the parameter in
all parfiles in the previous checkpoint subdirectory, in addition to
changing it in the top-level SIMFACTORY directory. <br>
<br>
In any case, if you also suggest that then I'm going to give this a
try again over the weekend (or on Monday - our computing center is
on a shut down for the weekend).<br>
<br>
Thank you <br>
Dumsani<br>

steered on recovery in this manner, by changing them in the
parameter file. Be careful when steering the out_every
parameters; you almost certainly want out_criterion =
divisor, not the default of "iteration". "iteration"
outputs if the current iteration number is N greater than
the last output iteration. "divisor" outputs if the current
iteration is divisible by N.<br>

I assume Dumsani refers to simfactory. How do you change the
parameter file that simfactory tells Cactus to use for a
restart? I admit that in that case I usually go in and change
the file in the output directory (simulations/name/...), but
there must be a better way. I didn't have to do that so often,
so I never bothers to find out myself.<br>
<br>
Does simfactory actually observe a --parfile option on
submission of a restart? It probably will not complain if you
try, but does it actually do what you want?<br>

<div>That I do not know. It would be nice if it did. What I
usually do is change the top-level SIMFACTORY/par/*.par file.
I don't think simfactory reads anything from restarts; it
only reads from the top-level SIMFACTORY directory when
creating a new restart.</div>
