(moderation:
it's not very long that einstein is working on my computer and at the beginning it went very fast: it took half an hour to complete a work.. now, after about two weeks, it takes hours!! about 7 to complete a work!! does anybody know why????

Work units come in two sizes. Short and Long.

Nope, if fact if you look at the crediting, the old units you were getting were less than 12.50 each. The new ones are running approximately 112 each.

Hi,
...Still another related question...
Question: Is there a way to get only the short WUs???
I noticed that I'm getting large WU - when I wanted the small ones....
I thought the parameter below would control whether
you got a small or large WU.
General Parameter:
"Connect to network about every ______
(determines size of work cache; maximum 10 days)"
My laptop is slow and I have to throttle it to control heat-up.
So the small WU ia also good for this and:
- a faster turn around time
- Less loss to recoup when suspending and restarting.
(Shutdown needed when traveling with laptop daily.)
I had the connect time set to 0.35 days.
Any insight anyone can share?
Thanks, Jay
There's no way that I know of

There's no way that I know of to pick long vs. short units.
There are a subset of the slowest computers that always get short ones but I don't remember the requirements.
If you are super interested, I can poke around and find the thread for you.

T H A N K Y O U!!!!
I have been running on the same, slow, computer -
and noticed that it went from small to large WU.
I didn't know if E@H had
a) temporarily run out out short units
b) Changed all to long units
c) Something I changed in the configuration. (Like storage allocated)
(Since some Boinc params are shared for all; projects....)
d) something else.
I did spend 2+ hours looking through the posts - but
I might have missed something.
If you have seen something along these lines,
please pass it along.
Thanks again, Jay

Here's the link to Dr. Allen's post on the matter:
Long WU Criteria
The only part I'm not clear on is how they determine the credit per CPU second.
Essentially it works out that roughly 1GHz class hosts and faster will get long WUs.

Thanks for digging up that

I was just popping by to find it.
LOL!

Hosts whose benchmarks place them among the slowest 20% of hosts are given short WU if possible. The remaning 80% of machines get both slow and fast WU.
