There are about 7 days work left for 10_223P what is next ?

i would say more 6 days (prediction). Richard told me what's would be next after 223, but i can't remember exactly. I just remember it's something between the 811 and the 223 in time of running. It's good to see another completed project.

4 days left, counting today ( @~500 workunits a day) so it should finish
Friday March 23 2004

March 23 (today) is a Tuesday.

You are correct, I put in today's date the 23rd instead of friday's the 26th.

all we know (or we hope) is the current project will finish this week :)

as we can see in the Work Units section, we are decreasing in speed :(

Actually, the current project is not even close to finishing. Ditto for M811.
The linear algebra still needs to be done.

if i've 2 relative good machines, do ya think i can help with something to close these 2 projects?

Correct, but that work is not performed by the NFSNET clients. From their point of view, the project is close to finishing.

Both views are correct, in my opinion, because the term "project" has this intrinsic ambiguity.

Certainly if your machines happen to be large Crays or Beowulf clusters.

The linear algebra is not something that can be distributed.

Unfortunately not.

You also need

a few dozen gigabytes of scratch space (not so hard to come by, these days)
a way of getting several gigabytes from "here" (either Cambridge UK or Austin Texas) to your machine
specialised software not generally available
significant expertise, also not generally available
either a cluster with multiple processors, a few gigs of RAM and a high-speed interconnect or a supercomputer, again with a few gigs of RAM. You need to be able to have exclusive use of this resource for a period best measured in weeks.

There may be other requirements that slip my mind for the moment.
