Re: Minnesota Crunchers

There is something weird in tonight's team figures. The total time is listed as
1:157:00:45:34 and the number of units returned is listed as 4707, both a little more than normal, but not too much, yet the points are listed as
6,281,640, which about 3 times normal. There is something screwy about the number of points. The time listed for yesterday is 1:165:13:38:33 which is a little more than today with yesterday's points being 2,457,256 and yesterday's units are 4,164. Something is off kilter.
Cheers

A few of us have powerful GPU's running the Beta for OPN for GPU. Looks like mbotmiller, mclaver, and myself at least. The work units are apparently about 20 times the work of a CPU work unit but finish in a fraction of the time, hence the points increase. Can't speak for the others but my GPU's have several thousand "cores" each. I imagine there will be some discussion around whether the points granted for the GPU's are appropriate compared to CPU. In the end it's the science that really matters and we have the chance to accelerate the research by an order of magnitude, so hopefully they get it going soon.

Edit: Think I see what your getting at now, Joe. My machines processed 26 pages of betas, 15 work units per page, and around 500-1000 points per wu. It should add up to around 300,000 points. But one of my machines did 1.1M and the other 1.3M points yesterday. So perhaps there is an big error somewhere.

If your machines did a little over 2 million in points rather than 300,000 that would have accounted for 1/3 of the perceived overage. So together with the other gpu users that would account for the great total in points yesterday. However, I only see a difference of about 600 more work units done. With a difference of 4 million points accounted for by 600 work units would imply a credit for each of the additional work units of about 6600 points. My average credit for a cpu work unit is about 80 boinc/560 wcg points. The totals might be off by a factor of 10. (Perhaps somebody moved a decimal point over to the right by mistake.)
In the big scheme of things the points don't really matter, the important thing is the work gets done quicker and accurately.

Re: Minnesota Crunchers

Just for the numbers people out there, today April 3, 2021 as written in month/day/year format with a two digit year would be 4/3/21. Just might be a lucky day somewhere. Might even have been a fortuitous day for a rocket launch.
Cheers

Re: Minnesota Crunchers

More recreations with digits and numbers in dates, more specifically, this year …
1-9-2021 (three sequential numbers can be recognized here: 19, 20, 21).
2021-2-2 (three sequential numbers can be recognized here: 20, 21, 22).
12-02-2021 is a palindrome in digits (of course, also 2021-12-02).
4-3-'21 is a decreasing sequence of digits.
5-3-'21 is part of a Fibonacci sequence in decreasing order (5, 3, 2, 1).
7-3-'21 can be written as a product: 7 * 3 = 21. (Also: 3-7-'21, 21-1-'21)
Each twelfth day of the first nine months of this year is a palindrome in digits: 12-1-'21, 12-2-'21, 12-3-'21, 12-4-'21, …
2021 is the product of 43 and 47, or (45 - 2) * (45 + 2) = 45² - 2² = 2025 - 4.
2021-03-19T14:46:56 = 1616161616 seconds since 1970-01-01 00:00:00 UTC; 16*16*16*16*16 = 16^5 = 2^20 = 1048576 = 1/2 * 2^21 (12221, didn't we see those digits before? yes: 12-2-'21).
One last look at 2021 for now: 20*21 = ten times the answer to "What is the meaning of life, the universe and everything?"

Re: Minnesota Crunchers

Big lightning storm last night. I shut down my systems and went to bed. It was a good thing because we had a power outage for little bit just after I hit the sack. I just left them off until this morning just in case there was a repeat. Everything fired back up this morning with no problem. I don't worry too much about the Linux systems as they seem to recover from outages pretty well, but unexpected power loss to the Windows systems seems to create unforeseen problems. Thankfully, I did not have to deal with any of that. It was all a big show, but we only got a trace of rain out of the whole business.
Cheers

Re: Minnesota Crunchers

Didn't get much rain by clearwater. Nice lightning show though. Looks like more tonight. I have both of my crunchers on a UPS so protected. Just had to replace the batteries for one last week. Good insurance though.

I have thoght about a UPS for the bank in the shed, but I have 5 machines running there on two separate circuits, so I would need two of them. Since they are all on Linux, I don't worry too much except for a lightning strike which may overwhelm the lighting protection in the power strips. I had another little outage last night too, but i am mostly back up and running now.

Re: Minnesota Crunchers

Looks like Open Pandemics GPU work units just released. Got a couple. 27 minutes estimated run time on my GPU.

EDIT: They are only Intel GPU at the moment.
