Orthos "blinks and beeps" more when there is an error Smile

I've tried Orthos, and 255 and 255A and they all seem to be doing
essentially the same kind of testing. I find Orthos seems to take
a bit more time to get started.

I don't understand the source of the 255 and 255A variants. They were
found in the mersenne.org/gimps directory, and were not indexed in the
"freesoft" section. The reason for that could well be, that someone
contributed a multithread version, and since the "official" development
people didn't produce it, it was hosted on the server but not advertised.
I wouldn't have found that one myself, except to see it mentioned on
an overclocking web site. Otherwise I'd still be using the Orthos
version.

LOL, I thought about that afterwards. The green/red "Paging" thing is a
great feature. Wink

Yep. I agree, they all seem to use the same engine. However, P95 25.5 will
automagically start as many threads as there are cores. That's gotta be a
bonus no?

That's how I found it too, reading web forums on OCing.

It sure would be!

As have I. It is comforting to know that it is available frome mersenne.org
by
FTP . ftp://mersenne.org/gimps/

I was going to check-out which APIs it uses with QuickView first.
