I can see where you had some questions on how to best adjust the default
setting on the client, but I'm going to leave those for someone else to

For the % completed so far, obviously we are going slower than the rc5-64
project.  Rc5-72 is a much more difficult task and the project hasn't grown
in size to compensate.  However even with rc5-64 my recollection is that,
while it took 1,726 days (almost 5 years) to find the key, it took at least
1 year and I think almost 2 years to pass the 1% complete mark.  

Towards the end of the project, we could have redone all the work from the
first year in a matter of days.

That gain was due to gaining additional support in terms of new
participants, additional performance optimizations in the cores, additional
computers being added, and Moore's law raising the speed of new computers.
Using the 18 month doubling rule of thumb for Moore's law, by the end of the
project new computer performance had doubled over 3 times since the

I wish the key rate history for rc5-64 was still active so I could double
check my recollections, but they should be too far off.

So I wouldn't be too discouraged by the fact that rc5-74 is still at only
0.247% complete.  That rate is bound to improve greatly.

Jim, Thank you for the response.

1st, please let me say that the clients are very well programmed!  And I
agree that they are ready to go out of the box.

And let me also add that I have enjoyed my very short
time at Distributed.net and learning about
distributive computing.  And trying to submit as many
work units as possible with x86 chips :-)  Darn mac's!

But here is my insight.  And remember I am new and
represent a completely non-informed and non-biased
humble opinion.

It was difficult to find my way to this list to talk
with other knowledgeable people about the project and
client.  I mean, it took me 60 seconds to download and
start the client, but 3 weeks to find the conversation

Then, when I first downloaded the client and started
running, I wondered what the heck OGR-P2 was.  And why
since we were going after the RC5 crack, what was I
wasting time on OGR.

Then several of my computers only have sporadic
Internet access to transfer files.  And I didn't want
them to run out of work.  It would be nice to have a
help file that explains to people what would be
optimized for their system.  If you are running a
500MHz P3, 24 work units is a days supply, but if you
have the faster PC's, that would take more than 5+
connections per day to transfer files.

Jim, I am not just a complainer :-)  I would love to
learn more and to help other Distributed.net people
maximize their efforts.  Anything that I can do to
help, I will be more than willing to do.

Does the client configuration have a help file that
really details out every aspect of configuration?

My last thoughts, where have all the people gone? 
Were a lot of people that participated in RC5-64 put
off because of the size and time duration required for

Have a lot of people went to other distributive
computing projects?

How can we attract and maintain more of the people who
come to Distributed.net?  There have been over 65,000
people who have submitted work, but only @ 15% are
active on a daily basis.

Again I wasn't around for the 64 crack so this may be
a completely normal performance %.  But as a new
member I wish it were more.

Thanks for listening and let me know if there is more
that I can do to help.

Partly because no one's ever raised it as an issue and
partly because 
one's volunteered to write it. What specific issues
are you having? The
client is intended to be as ready-to-go out of the box
as possible.

Most likely a network.
