Its looking likely I will go ahead with the purchase of another computer which gets to the important issue of what to call it? The two I already have are called Shake & Bake. It has occurred to me to call it 'computer' in much the same way that someone might call their dog, 'dog'.


Perhaps you could have Shake, Bake, and Quake? :)

Got a late start (about 80 minutes), but I am in now. Will be running a bit underpowered through much of tomorrow as an AC unit is replaced.

Are you using an account manager such as BAM? If so, settings from it might cause such problems.

I thought that I would weigh in on this discussion. As I see it, the are points to be made on both sides of the issue of searching primes wherever one likes.

On the side of searching as one likes:

1) Science and mathematics are driven by an openness of sharing results to be reviewed by others and to have those results available for the benefit of society at large (although, of course in some circumstances, corporate and other interests may delay that accessibility).

2) Prime hunting has traditionally been a free endeavor where one's interest and personal goals typically drive one's search. This is not different at PrimeGrid where a cursory search through the forum will yield numerous instances by a number of posters making that exact point--and often these are comments coming from PG admin regarding which PG project to run.


On the side against searching as one likes:

1) Projects often exist (not just in prime searching) to provide a systematic approach to discovery. In the case of some prime searches (e.g., SoB), this is an essential approach as efforts to "search ahead" might lead to unnecessary work when a smaller prime is found before reaching that advanced search range. In other projects, it is a helpful way of organizing a search for a number of reasons. For example, the GFN projects were often searched in the past in a more haphazard manner that is now being processed to fill in those gaps (e.g., the work at PG, the work on GFN13 and GFN14 being done on a private server).

2) "Searching ahead" is a waste of energy on most prime projects. In most cases, even modest advances in the range searched results in considerably larger numbers being examined. These larger numbers take much more processing time to run. Assuming no advances in software, hardware advances would make those searches much more efficient once reached in a systematic search than would be done by searching ahead on current hardware. This effect is often exacerbated by software development making those searches faster on all hardware. (Indeed, under this point one might question why PG runs either the PPS-mega or GFN17-mega searches, but those searches are being done in tandem with searches that are filling in the gaps.)

3) "Searching ahead" creates extra work for a project administration that should be unnecessary.

4) "Searching ahead" could cause much larger problems if more computing were doing this type of work. Certainly this would be the case if a significant percentage of PG users decided to do this, but that scenario is not very likely given the technical skill threshold to conduct such searching. However, a much more likely scenario that could occur would be if a "larger" user decided to do this approach to prime searching. Imagine, for example, if I were to decide that I would skip ahead and search GFN21 well ahead of where the PG search is right now. Would other users be upset by that?


While there are arguments on both sides of this issue (and I am sure that there are other points that could be made), there has been a practice in the prime searching community (as occurs in other fields) to establish an etiquette for how to conduct one's searches. These include things like crediting software developers, etc. for the tools being used as well as avoidance of knowingly searching the same candidates as another person or group. "Searching ahead" on a project that is already ongoing strains this etiquette, and at least in my opinion, should be avoided.

As has already been noted, there are literally an unlimited number of types of primes to be found. PG already has ongoing plans to search GFN primes at much higher ranges, but will do so systematically. While there is nothing to be done to stop anyone from searching those advanced ranges first, I would encourage anyone considering such actions to think about how that affects prime searching projects (not just PG) and the overall endeavor of prime searching.

And when I went to Tokyo for 26.2 I had to request the "XL" t-shirt size and even that is a bit snug.

My experience in Japan (visiting my wife's family years ago) was very unexpected for a physical giant such as myself--I am 5ft 8in or about 172cm. One of my wife's aunts has a home from the 19th century (1880s as I recall). When visiting them the first time, I entered their home last in our procession. As I strode across their living room to greet them, I slammed my forehead into a ceiling beam! At my height, that is one experience that I was never expecting to have.

One lonely mac on autopilot, and:

Very nice, well done.
Welcome back btw, if you're back.


Jeez, was I really gone that long :)


94 days from the forum to be exact. Glad to see you here again!

Just what *are* you running at home??


A Quad-core Haswell Xeon (mine) and an i7-4790 (the wife's) as the main two systems, but the upgrades aren't on CPU.

My GTX 1060 6GB is being replaced with an RTX 2060 (needed the tensor cores as we are starting to play with them at work and I needed something to match up with my 2070 at the office).

I will be replacing the wife's aging 2GB GTX 960, likely with a GTX 1660 Ti. I am also moving her over to an SSD from her old 7200RPM drive (my macine already has that setup).

Congrats to Z-San and Scott! Well done all you ratties!


Thanks! Was hoping to break the 10 million barrier on this one.

Now, time for a couple of summer upgrades to the home systems. :)

The most bang for the buck is probably the 1660 at stock prices (in US dollars):

1650 $149 896 shaders ~6 shaders/dollar 1660 $219 1408 shaders ~6.4 shaders/dollar 1660 Ti $279 1536 shaders ~5.5 shaders/dollar
