How to read the "Exponent Status Distribution"
Hello again, and sorry for another beginner question.
When i look up the "Exponent status Distribution" list under http://www.mersenne.org/primenet/ I see the list of all work types and how many are left of each kind, i assume i need to read the table from right to left, see attachment, a work type is done when the column Available is empty. Correct? The table "PrimeNet ECM Progress" under http://www.mersenne.org/report_ecm/ shows me the same only for ECM? Example: So when i have checked the option i only wanna have the smallest possible assigned and forced the Work type to ECM, I should get ECM between 0 and 1.000.000 regarding the attached photo. Maybe this is all in the wiki, I dont think so or I dont know how to search it. Feel free to post a useful link. English is not my native language, I apologize for any Grammar and spelling mistakes and promise I will get better! Thank you for your answers Gabriel aka 3mg4

No problem at all. Every question (and answer) adds to the archive of GIMPS help, information, and answers that this forum will offer for years to come.

First of all I apologize for my ugly english.
I'm a new forum's user at this moment just out of curiosity. I red your post about the Exponent Status Report. Very clean explanation. But.... I am searching for the status of each exponent. May you help me?

Have you found this link ( http://www.mersenne.org/report_exponent/ )? From the PrimeNet page Reports> Detailed Reports > Exponent Status

Great, explanation Nathan. This is exactly the information I was looking for.
That said, I do have a few follow up questions for you if you don't mind. Quote:

Thanks in advance for the additional details. And thanks again for this excellent summary of the Exponent Status Report.

Thanks!
In regards to the first question, I still don't fully understand. That said, you've answered the question I just need to ponder on your response a bit and maybe it will come to me. Yes, this definitely clears things up for me on the P1 vs TF questions. I also came up with another question regarding the Exponent Status Distribution. Specifically the values listed under Assigned and Available TF. https://www.mersenne.org/primenet/ It may be easiest to ask this question via an example. I see that the 111M exponent range has a range count of 53,816. And, as I understand from your previous post, this is the number of prime numbers between 111M and 112M1 (though I still need to do some work to understand why). I also see that there are currently 14,220 TF assignments associated with this exponent range with none available. I'll come back to this in a moment. My GPU is currently working on ~6,000 TF assignments in the 111M range. For all of the assigned values it appears to be testing a range from 2^73 to 2^74 (I selected "what make sense" when requesting these assignments). From these links https://www.mersenne.org/various/mat...rial_factoring and https://www.mersenne.org/report_expo...2918073&full=1 I can see that TF'ing is completed in stages (though the factoring cost appears to have changed slightly since this table was published based on my testing interval of 73 to 74 on exponents in the 111M range) with each stage generally assigned out over the course of many years (Moore's Law at work I assume). Back to my example question. How are the various bit levels captured in the Assigned and Available TF data fields? In other words, what are the units of Assigned/Available TF? Is 1 Assigned TF equal to 1 Range Count in terms of units, if that makes sense? Or, is 1 Assigned TF equal to 1 bit level of 1 Range Count? I'm sorry these questions might not make any sense at all, but I'm trying to understand what I'm looking at in the Exponent Status Distribution vs. what my CPUs/GPUs are actually telling me they are working on at the moment. I feel like I need to sit down with someone much more knowledgeable than myself for many many hours  each with beer in hand  and discuss a wide variety of GIMPS related topics that are still a bit fuzzy to me. That said, I am still learning by reading and asking questions on this forum. This team does a great job of supporting those of us that are interested in supporting the cause but are very ignorant of what's actually going on behind the curtains. And for that I thank you.

Those are "small" primes, fast to generate. Remember, the primes are from 111000007 to 111999997 and not from 2^1110000071 to 2^1119999971 which, if prime, is a Mersenne prime. nemonusquam
