Dear All,
<div><br>
</div>
<div>Apart from discussing the answers to the SPC we should also discuss:</div>
<div><br>
</div>
<div>1) Progress with disconnected diagrams (Chris C.)</div>
<div>2) DA calculations (Daniel)</div>
<div>3) GPD paper status</div>
<div><br>
</div>
<div>Cheers,</div>

<div class="">Dear PI,</div>
<div class=""><br class="">
</div>
<div class="">The SPC are discussing the proposals received for the USQCD computational resources, and will finalize allocations over the next couple of weeks. As I mentioned at the AHM, the demand is almost a factor of two over available resources, except
for the GPU resources (The 21g is oversubscribed by a factor of 2 as well). If you haven't mentioned it in your proposal, but can use the non-21g GPU resources efficiently, now would be a good time to mention it.</div>
<div class=""><br class="">
</div>
<div class="">In addition, while reading your proposal, we had some questions. We would appreciate if you could provide some clarification by return email, as soon as possible, and definitely by this weekend. This will help us better evaluate the expected
benefit to USQCD of the allocation we recommend for your proposal.</div>
<div class=""><span class="" style="font-size:12pt"><br class="">
</span></div>
<div class=""><span class="" style="font-size:12pt">Q1. Which deliverables would you prioritize in case the allocation is reduced?</span><br class="">
</div>

<div>KNL = 50% contractions for flavor-singlet hadron structure and 50% peramabulators and genprops on 48^3 lattice</div>
<div>21g = perambulators and generalized perambulators</div>
</div>

<div>We can certainly move 19g -> 21g - note latter undersubscribed. I would prioritize two-point functions on KNLs.</div>

Maybe we should think about this.</div>
