So, what is almost certainly a mipsplepping or a typo, is misinterpreted as wrong word choice, purely for the sake of pedantry. But in quibbling over the imagined wrong word choice, the pedant commits a substantive error of fact. Entertaining to be sure!

For 'tis the sport to have the engineer hoist with his own petard; and 't shall go hard, but I will delve one yard below their mines, and blow them at the moon. -- Hamlet, Act 3 Scene 4

I was unaware that "horde" was a verb, but this usage is in my old Merriam-Webster Second Unabridged. My vocabulary is enriched, albeit minutely. Horde is rarely used as a verb, having to compete with such noun/verb words as as crowd, pack, and swarm. Or the verb converge, whose adjectival rendering convergent appears in the name of a well known insect, the convergent lady beetle (or "lady bug"), Hippodamia convergens.

"It is not a deliberate mass suicide, in which animals voluntarily choose to die, but rather a result of their migratory behavior." https://en.wikipedia.org/wiki/Lemming Are all myths and fictional characters and plot lines also off limits, to make a point in the forum? Say, Shakespeare's as well as Disney's, Heminway's, Asimov's, ...? We'd be the poorer for it. Ok, upon further review, whording has a certain appeal. Hadn't seen that one before.

I see your point Uncwilly. I later completed M104056283, then see Team_Inspector do it with larger B1 and B2. It is unproductive two people doing the same exponent.

Unless I write otherwise, I will not be doing any more of Lisander Viaene's exponents. If I do change my mind, I will announce the exponent 24 hours in advance. If someone says they have started an exponent, I will not start it.

*Ben got the PRP test of one I did earlier, but I realised I'd make an error in the worktodo.txt file.

 2021-06-24, 12:54 #27 slandrum   Jan 2021 California 101100102 Posts What I'm failing to understand is the lengths to which you are going to circumvent the server assignments to grab cat 0 assignments. This gives you exponents that are maybe 1-2% faster to process than if you just let the server give you cat 1 assignments, and your efforts at times are counterproductive. I'm not sure what the actual goal here is. You've suggested at times that you don't want to waste a lot of time reading through all the discussions here or read through all the reference posts, but you have the time and energy to try to circumvent the way things are set up to operate.

That was not really my intension.

Performing P-1 factoring followed by a PRP test will not save 1-2%. It will take longer than doing a PRP test of a slightly larger exponent, which are usually issued without the need for doing P-1 factoring. If one adds up the time doing the P-1 factoring, then the PRP test, it actually takes longer.

Yesterday I was allocated both M103822073 and M104139887, both of which had P-1 already done, and both smaller than anything Lisander Viaene has. It just seemed that it was wrong for Lisander Viaene to hog these, doing nothing, when others could be working on them.

Why not just do a bunch of P-1 on the following exponents (all have not been checked in since June 4) if you want to liberate the exponents. Use your power to facility others as opposed to doing the PRP yourself (and getting in a race condition with other users).

Code:
104093201
104182469
104204549
104212477
104215453
104216863
104219327
104219849
104226361
104231033
104231681
104235323
104241121
104261057
104261107
104261137
104261263
104265443

 2021-06-24, 14:24 #30 drkirkby   "David Kirkby" Jan 2021 Althorne, Essex, UK 3·149 Posts If you look at my rank doing PRP tests https://www.mersenne.org/report_top_500_ll/ (currently #75, with 43428.065 GHz days) vs my rank for P-1 factoring https://www.mersenne.org/report_top_500_p-1/ (currently #190 with 571.743 GHz days) it should be clear my interest is PRP, not P-1. But I did the P-1 on a couple, despite I'm well aware it is not actually cost-effective in time. Last fiddled with by drkirkby on 2021-06-24 at 14:25

Then bypass the P-1 on Lisander Viaene and start on the PRP's directly and stop carping and wasting everyone else's time. If you don't know how to do that Don't complain that you don't have an assignment for it. You have shown a willingness to poach already.

Stop winging at me. I'm well aware how to do/stop the P-1 - just change 0 to 1 in assignment line. But skipping is a bit silly, as it can save a lot of time if a factor is found. With the default parameters, the probability of that is around 4% - and no need to pick me up if it's nearer 3% or 3000%
