@Simon - done, thanks - I put the clinfo-issue fix in the Troubleshooting section of the OP.

16GB should be OK with just 1 instance running, but suggest watching progress through at least one p-1 stage 2 ('P2' in the progress-line just right of the exponent): If that takes more than a few hours, maybe ratchet things back to 14-15GB. (I always run 2 instances per R7, but perhaps other 1-instance runners can comment on whether maxAlloc of 16GB works for their p-1 stage 2s).
