It will be interesting to see what the papers say when they are released/published

Aurum420 Out of complete curiosity can I ask what age range of hardware you are using thank you are seeing checkpoints takes 6+ hours, does this increase the length of the overall task?

Yes I agree ARP does not like hyperthreading hence why I only run on 12 of my threads at a time. Thanks for PDF document. The way I see it having slower CPUs are good for adding to your runtime

Whilst I agree with the observations made, I find hyperthreading works if arp is restricted to half the threads or mip to one third of threads. However I don't push my luck.
With both together on an 8 thread machine, i7-3770 with 4 cores, I have set its profile to 4 arp, 2 mip, 3 mcm and 2 opn. That allows me to hold 3 units in reserve.
app_config.xml is set to 3 arp, 2 mip, 2 mcm & 2 opn. The one that doesn't get its full quota is usually mip because that has a 10 day deadline and the others have 7 days, but it allows for possible interruptions in supply for long enough for me to spot.
My older, slower, laptop with 4 threads isn't set to run arp ever since it was given a 3.5 day resend which regularly took 4 days plus queuing time and didn't get its credits. That resend should never have gone to that machine. It is set up for 2 mip, 2 mcm and 2 opn, but only runs 1 mip at a time, because of the longer deadline, with 3 between the other 2.
That leaves my tablet & phone which are both 4 core/thread and are currently running mcm & opn.
All are set to also receive scc whenever it returns. hst is not set at the moment because I already have diamond (5 year) on that, but should come back into play once the others have reached that target.
mcm is the exception because I am 4.5 years away from my 20 year badge and I have prostate cancer, thankfully reduced to a very low PSA now.

arp are readily available, but that doesn't mean that they are instantly available. They are still releasing them randomly. I suspect that you have requested a new unit when the latest batch has just run out. The next batch should be released soon. I hold a cache of 4 units, 3 of which are running at any one time. I normally have all 4 but for brief periods I sometimes get down to 3.
