<div style="margin:0;">Dear all,</div>
<div style="margin:0;"><br>
</div>
<div style="margin:0;">Following my presentation of Geodesic at
the previous weekly users call, I would</div>
<div style="margin:0;">like to give a brief status on the one
item I flagged as an open limitation:</div>
<div style="margin:0;">exercising the multi-process (MPI)
configuration on a Carpet AMR evolution.</div>
<div style="margin:0;"><br>
</div>
<div style="margin:0;">The single-process + AMR runs already
reproduce the unigrid reference orbits with</div>
<div style="margin:0;">the three samplers, with no lost
particles and no NaNs. Since then I have been</div>
<div style="margin:0;">working on the MPI path, but the work is
still under test: current MPI + AMR runs</div>
<div style="margin:0;">still show particle loss with non-finite
metric samples, and I am debugging the</div>
<div style="margin:0;">cause. I do not yet have a clean,
reproducible result, so I have no conclusion to</div>
<div style="margin:0;">report this week.</div>
<div style="margin:0;"><br>
</div>
<div style="margin:0;">In short: no new deliverable on the MPI +
AMR path this week -- it is still under</div>
<div style="margin:0;">verification. I will report a concrete
result as soon as the verification passes.</div>
<div style="margin:0;"><br>
</div>
<div style="margin:0;">I remain available to discuss, and as
before I am most comfortable continuing</div>
<div style="margin:0;">in writing. Any questions are welcome.</div>
<div style="margin:0;"><br>
</div>
<div style="margin:0;">Best regards,</div>
<div style="margin:0;">Yuhua Li</div>
