Hi,
re:

I can be available today at 14:00 MST. Monday is still OK for me too.
re:
> Bruce Chiarelli (CC'ed) may be able to answer these questions better.
OK.

Very good.

I really asked the questions to set the framework for the discussion we will
be having.
re:

If I recall our previous Zoom sessions correctly, I seemed to recall coming
to the conclusion that it would be best if your LDM queue size were
significantly
larger than what it is now. This, in turn, would require that there be more
vRAM in the VM.
re;

The other thing I think I recall was commenting that having more vCPUs
available in the VM would be very useful
re:
> 3. To run the LDM with no additions at least 64 GB of memory is needed

Yes, a VM with this much memory and additional vCPUs would give you an
environment where you could implement all of the processing that was
being done in your old environment with plenty of room to grow your
activities.

Very good.

Excellent.
re:

Excellent.
re:
> Please let me know if you need any additional information.
No, that is enough to set the stage for our upcoming discussions.
re:
> Thank you very much for your time and help.
No worries.
Cheers,
Tom
