Individual Account Report queries
The client has been running on my home and office system since about 7 days. Still I get the following status:
LL P90* Exponents Fact.P90 Exponents P90 CPU CPU yrs LL Tested CPU yrs* w/ Factor hrs/day      0.000 0 0.001 0 1.46 The P90 CPU hrs/day value seems to be decreasing every day. What is this? Why doesn't the value of Exponents CPU yrs* change? Then, what does each of this this mean? prime fact current days exponent bits iteration run / to go / exp date updated date assigned computer ID Mhz Ver One of my prime exponent doesn't have a *, has been running for 7 days and there are 6 days to go. What does it mean? The other still has a * after 7 days (That PC is slow & I am testing 10M number there!!). What does that mean? Thank you for your help, ...Shu

OK, let me have a go at trying to answer this...(moderators, if i am wrong can you please correct me)
Quote:
prime exponent: this is the exponent that you are testing. therefore the mersenne number that you are testing will be 2^(prime exponent)1 fact bits  shows how far the number has been factored to without finding a factor for example, if it was 68, all factors up to 2^68 have been tried but none of them are a factor current iteration  shows what iteration you are up to. when the number of iterations equal the prime exponent, the LL test is complete and you will know if the number that you were testing is prime or not (hopefully it is) days run  how long it has been running for davs to go  approximately how long until the test completes exp  how long before the exponent expires and is assigned to someone else. however, don't worry if days to go is higher than exp. every time that you update the server, the days before expiry are set back to 60 again. so just make sure that your computer is connected to the internet at least once every 2 months so that it can set the expiry back to 60 again. date updated  the last time your client conected to the server date assigned  the date that you checked out the exponent from the server. computer id  the name that you gave your computer (only really important if you are part of a team Mhz  the speed of your computer in Mhz Ver  what version of the client you are using Quote:
Therefore, for you first computer, it has started the LL test, it has been running for 6 days, and it still has about another 7 days of crunching to go. For the second computer, it is still trying to factor the number, then it will start the LL test I hope that this has answered your questions. Hopefully I haven't confused you any more.

Thank you very much dave_0273.
It certainly did not confuse, it was very helpful. Regarding "If no factor is found, the asterisk disappears, and the assignment remains on the list until the 64bit LucasLehmer residue is returned. When the residue is returned, the completed exponent is moved to the Cleared Exponents report" So, is the number being tested for being prime or not? What is the "64bit LucasLehmer residue"? Would we know whether or not the number was prime after 7 days? When do we come to know whether or not the number is prime? Now, regarding "This is the number of hours of work in a day that a 90Mhz computer would do. It gives an average of how many hours work you do measured in how long it would take a 90Mhz computer to do the same amount of work." I have one P4 2.5G and one P3 800MHz system. The faster system is my office PC that stays on 24 hours a day. With that logic, shouldn't the hours per day value be some 10 or 20 times (atleast) the multiple of 24? After all, how much can my home system degrade the overall performance. Still, my rating shows 1.46. Any explanation for this? Thanks, ...Shu

As for why your P90 CPU hrs/day is so low, this i can't explain. Maybe one of the moderators or someone more knowledgable than me will be able to answer this one for you.

P90 CPU hrs/day: I think this entry means: The worth of completed work measured in p90 hours, divided by the number of days passed since you started prime95 the first time.
Example: You tested some exponent. You got some p90 CPU years credit and the "P90 CPU hrs/day" now reflects the amount of work your box did in an average day. Until the work on your next exponent is completed you will not get any credit for it, the entry for "CPU years" will therfore not change, but "P90 CPU hrs/day" will decrease and decrease every day. When the exponent is completed you will get p90years credit for it and the "P90 CPU hrs/day" entry will again reflect the work your box did in average day.

You only get credit for an LL test when it completes... and then you get all the credit at once. Because of that, the "P90 CPU Hrs/Day" figure is not very meaningful, you shouldn't worry about it.
