Default Prepare the way! SRBase is coming for the next bit level.

SRBase is turning results in 967M at the 72-73 bit level. Those who are working down in the 120-200 range at the 73 to 74 bit level may want to start up at the 74 bit level now. I know that most folks are watching out, but I figured a heads up would not hurt.

It sure would be nice if they kept their fire trained on the exponents less than 332.2M, instead of doing TF on exponents that won't be tested for a LONG time.

That is not happening though. Gift horses and such.

The SRBASE breadth-first approach is not original. Wasn't GPU72 or some other group doing the same? TJAOI something similar?

As I recall, the frequent results produced by low bit level TF are part of SRBASE's appeal, to those to run BOINC, so providing more throughput.

It does provide on occasion a little benefit on scattered deep tests. In two subprojects:

...

223606807
271828199
292005113
314159311
853973437

One could also claim that people working at the 73-bit level really ought to be taking exponents up to the recommended bit level for P-1 and PRP, that is, 76 at the wavefront, or 81 for 100Mdigit.

Two of the pluses of participating in GIMPS are, there is such variety of work types and orders of magnitude range of work unit size, and we get to pick what we want to do within the limits of hardware and software capabilities and expiration rules and our own patience.

GPU72 always targeted the "optimal" before releasing, but offered "Breadth First" for anyone who didn't want to do the "heavy lifting".

But as you said, Ken... Whatever rocks your boat is fine. Heck, Wayne's "Less than two K" sub-sub project has no actual use for GIMPS, but it's still fun.

I did breadth first somewhat initially up in the 332M range.

Remember who did the big movement of all those expos at 332.x-333.xM few bitlevels when the GTX580's entered the market? Chris still had the movies for a while (and I saved them somewhere, I think). The forum still keeps the posts.

I do indeed remember. The little desktop 'toaster' style machine that I was using was slow.
