Interesting. rpcnet.dll from the v18 distribution is much
smaller than that in the v17 distribution.
Should be safe enough to keep the v17 distribution copy.
Yes, but it the v17 version uses a proxy running on the old PrimeNet
3.1 server's box. I'd rather everyone use HTTP if possible, or at
least use the updated v18 version dated 4/12/1999.
Ooops, sorry... I presumed that something had gone wrong which
was making the v18 rpcnet.dll misbehave and had a much smaller
file size as an indirect result ...
Actually my systems are all using either http or the special
rpcnet.dll used to connect to the PrimeNet Proxy server, so I just
don't know how badly the v18 rpcnet.dll is broken.
The v18 program defaults to HTTP when you first install it, so new
users should not run into it. The PrimeNet FAQ page also describes
how to handle the RPC run-time library crash situation.
I've updated the posted v18.1 zips with a new RpcNet.dll. I couldn't
get it to crash. If you have an environment that can test this,
please do so and tell me how it went.
I don't have a suitable environment, as I explained above. Perhaps
other people could have a go.
BTW, Scott, when you post new versions of software, could you
please either mail me or change the "last updates" date on the
PrimeNet News page. I didn't know that the files had been changed
until I read this message, hence by ftp mirror was still serving the
version with the "old" v18 rpcnet.dll. (I've just pulled the latest files
onto the mirror. Sorry to anyone who's been fetching over the last
few days)

You are merely restating a law of nature. After a point, everything
becomes useless.
I am reminded of a quote from Homer Simpson: "Trying is the first
step toward failure." :)
A question for George (and Scott): Is there any chance that Prime95's
ECM factoring will ever become automated as a part of PrimeNet? Even
if it is never given as a default type of assignment, it would still
be useful to dedicated number theory enthusiasts who want to run it
on more machines than they can manage manually.
For automated ECM factoring you might want to have a look at the ECM
client/server setup at http://www.interlog.com/~tcharron/ecm.html instead,
once you get it running it works quite well.

It also seems that the number of sumout errors [that is, sum(inputs) !=

My bet would be overheating or flaky memory - but I certainly
cannot prove that.
I understand that hardware problems certainly cause sumout errors.
If I had an overheating CPU or flaky memory, I would expect the problems to
continue but
they seem to have stopped for the moment. This is indistinguishable from
an intermittant hardware problem like a separating circuit board (or other
component).
Oh, well, and thanks.

Subject: Mersenne: Performance hit on Pentiums with 64MB?
I currently have a P200MMX with 64MB running Primenet under Linux. Finding
64MB rather limiting on my desktop workstation, I'm looking to equip the
machine with a couple of 64MB SIMMs.
However I shall be running into the limitation of most Pentium motherboards
in that the machine will be unable to cache more than 64MB of RAM. How
much of a performance hit am I likely to encounter in running Primenet?
I've seen figures of 10-30% quoted for various applications.
Not that I'm overly bothered - I have a PII contributing rather more these
