If anyone's interested in tea, try Whittard if you haven't. Excellent but not as expensive as East India Company. I recommend their Mango and Bergamot.


I've never heard of that but a friend told me about the "PG Tips" tea and it's darn good!! I am not a tea drinker but was for awhile, I still have a cup once in awhile but not very often. Coffee is my go to drink every morning.

I've never cooked with cocoa either!!


I prefer loose leaf tea, rather than pre-made tea bags.

But the tea and the DIY tea bags can be quite a bit more expensive than they should be...

Hey guys!
Haven't posted for a long time, although I never really posted much.
In the past year (or two) I've:
- graduated from secondary school, and
- arrived here in London for uni
- upgraded from a 330M to a 950M
So I'm definitely winning :P
Nice to be back crunching!


Welcome back!!
Yes the 950 should do better than the 330 for crunching!!
Congratulations on your 'moving on up', have you figured out what you are studying at the uni yet or is it too early to focus yet?

Yes JumpinJohnny the Super Moon was cool!!!

I am now winning!!


the 950M is definitely way better than the old one, I've doubled my credit in a month!
I'm currently going for a MSci Mathematics (a 4 years undergrad course).

For me (Windows 7), it's collatz_sieve_1.21_windows_x86_64__opencl_nvidia_gpu.config under C:\ProgramData\BOINC\projects\boinc.thesonntags.com_collatz\

The exact file depends on which app you're running run.

I believe for collatz_sieve_1.21 we no longer have items_per_kernel, instead we have sieve_size

I'm completely new to this, so can someone check my interpretations in layman's term:

verbose: doesn't matter. (1 = log stuff)

kernels_per_reduction: refresh rate. (higher = lower "refresh rate" = less time "refreshing" = better performance)

threads: not sure about this one. Doesn't seem to matter that much.

lut_size: make it so that 2^N <= GPU cache size. (my GT 330M doesn't have L2 cache so it doesn't matter?)

sleep: idle time. (less idling = better performance)

reduce_cpu: doesn't matter. (1 = use a bit more CPU instead of GPU)

sieve_size: The meat of the update. Increase until computation error / driver crashed.

My settings with a GeForce GT 330M:
verbose=1
kernels_per_reduction=48
threads=6
lut_size=10
sleep=1
reduce_cpu=0
sieve_size=27

Winning!!!


Not any more!!!

That's what you think.


Welcome back guys, it was getting lonely in here!
Is everyone all warmed back up again now? My temps are 3 times what they were the other day and it is still only 25 degrees F at 7am!


25F ~ 269K

269*3 = 807

807K ~ 993F

How did you survive?


I stayed indoors!!
I live about 25 miles South of Washington DC in the US. Right now it is 32F with some freezing rain still falling, but another few degrees and it should turn to all rain for the rest of today and tomorrow.


freezing rain? you mean snow? or hail?

I'm glad I live in Taiwan where is about 68F (20C) right now.


17C here at Hong Kong, but feel more like 12C or something with the wind...

Is it too early to put the decorations up?




My family just putted on the Christmas tree. The plastic one that we used for 10 years or something.

@SandJ I am too old to change the celebration date of my birthday now, it just is what it is.

Fairy nuff.

That doesn't mean I can't still be WINNING though!!!

That was my thought.

Mayhap, it is everyone's thought.

Sadly doesn't make them correct.
