11) Message boards : General discussion : Question about electricity (Message 32649)
Posted 3746 days ago by PilgrimProject donor
I used to have 18 machines, halve of which were 5 year old Pentium P4's.

All machines were connected into a 20 amp circuit but if my wife used her
hair dryer or the washer the circuit breaker would blow.

When I actually checked and found out one old P4 used as many watts
as 8 threads on a i7-920 and more than a i7-930, I got rid of them.

My electric bill drops in half if I turn off all machines, but then my electric supplier increased their rate 100% so I was right back where I started.

I pay for the remaining machines by turning off the heat if not home and all night while sleeping. For example, air temp last night was -10F with winds
of 25 mph. When I woke up this morning the house was 55 degrees F.

Then the heater kicks on. I do the opposite in the summer with air conditioning.

Now my bill is back to where it used to be, until the next hike in prices.

By the way, all my i7's, whether 920, 930, or whatever use 440 watts
each using BOINC at 100% with 8 threads.

Power supply on each is a Corsair 750watt.

I could afford to add decent GPU's to these machines but
I would be adding close to 300 watts per machine if the are going
full tilt.....that I CANNOT afford.

Unless I want icicles on my cats
whiskers int the morning.

We all have a way to go.

The #1 person on PG has almost 500 MILLION,
half a BILLION!

You will need more than an AMD to hit that.

This also hapens when you have been running a large
queue with 20 or 30 workunits waiting to be uploaded
and then the server runs out of work and/or is down a
day or so due to whatever reason. When the server
eventually comes back up or is reloaded I get the same error and lose hundreds of workunits and lots of CPU time.

It can be very discouraging.

This is the error I got trying to run with CUDA toolkit
and a GTS250........

2011-01-09 16:34:38 CET] GFN262144TEST: No data in file [genefer.log]. Is genefer broken?

(debuglevel=2).

I think I found my problem.

I have a GTS250.....which I
believe is not double precision.

Oh well...will have to save up to play
with the big boys.

I got the same error.

Downloaded correct package with correct dll.

Still got same error.

Renamed it like our friend tried to, then got a different
error for a different dll name.

Bit the bullet and downloaded the CUDA toolkit at
over +100MB.

Now, no more missing dll errors, however still does not work.

It starts up fine but then says no data, and suggests
I am missing genfer.log.

I am not.

I would suggest if possible to do a disk image or backup if you can
and download toolkit...see if that fixes the missing dll problem.

It did for me but still not working for some other reason.

Cheers

20) Message boards : General discussion : So which tasks are supposed to find megaprimes then? (Message 28906)

IF you have a fast processor, it is getting to the point on
PrimeGrid that if it takes 1-2 years to find a Megaprime,
you might as well look for a Mersenne prime and get some
cash to boot.

I know they are rarer but there are also more
participants. Plus you get a chance to REALLY
make history + $50,000.

On my two fastest machines, one work unit that would be
over 13,000,000 digits takes a little over 2 weeks or
about +350 hours.
