Thanks Dan for your

Thanks Dan for your explanations....I think I understand the complexity of it all a bit more

Oh dear! Just changed my

Oh dear!
Just changed my MacBook Pro to S5R
My BIG gun has just hit " h1_1339.0_S5R1__3203_S5Ra_0 "
predicted .... 5 hours 20 mins!!!!!!!!
What will happen when I get a big WU?????????

... my Measured Flops = 1742 million ops/sec
and Measured Integer Speed = 4734 million ops/sec

This is like atacking an elephant with a water pistol!!!!!!!

"h1_xxxx....."'s are long units-> that time will be way off. If its the first S5 units you've got on that machine it wont have got use to its times yet.

I think you’re confusing WUs and the data files from which they’re ‘sliced’. Short WUs can come from long data files and vice versa. Right now I’m crunching some short ones (@3-4h on an old Mac) whose names start with “h1_0384.0�; they come from a long (15.4-MB) Hanford file.

I am 41.2% through " h1_1339.0_S5R1__3203_S5Ra_0 " ..... at 2 hrs 19 mins

So THAT part of the equation is right.
How do I find out what that WU is?
Is it a short WU?
Is it a "long" short WU?
Is it a "short" long WU?
Is it a long WU?

Anybody out there with a hazard at the answer?

I originally thought that at first. Someone before in this thred I think said (think quoting bruce too) it was 0xxx.x=short and xxxx.x=long but i find that even more alarming. all the units a have are 'h1' and are '0xxx.x' and three i've got throught so far have taken over 11hours others estimated at over 13hours. If they are in fact short units then i'm frightend to think what a actual long one looks like! These are on a Pentium d 830 3.2ghz.

Seems that niether way works at distinguishing long/short.

This is what Bruce said

I'll update this as our generation and testing of our first S5 workunits proceeds
The names of these workunits are of the form h1_XXXX.X_S5R1x_* and l1_XXXX.X_S5R1x_*.

There are two types of workunits: short and long. The short workunits have XXXX.X less than or equal to 0400.0.

There are also two types of data files: short and long. The short data files (l1_XXXX.X) are from the LIGO Livingston Observatory, and are about 4.5MB in size. The long data files (h1_XXXX.X) are from LIGO Hanford and are about 16MB in size. Note: once your computer downloads one of these data files, it should be able to do many workunits for that same file.

So I am crunching a LOOOONG WU in 5hrs 20 mins ! This gives me 2 WU's in that time ... or a crunch time of 2 hrs 10 mins for a LOOOOOOOOOOONG WU!!!!

WOOTY - WOOT! WOOT!!!!!Anybody wanna buy a really good MacBook Pro????????? (REEEL CHEEEP!!!!!)
:-))))))))))))))

i think there are still differences between long ones. How much credit did you get for those?
Because i dont think you crunch a WU my Athlon 64 3500+ makes in 9:15 hours in 2:10 hours...

SORRY!!!! I was looking at wrong end of telescope!!!!
I apologise ... my mind was running away with me ...
EACH WU is being crunched in 5hr 20min
sorry ... I was wrong!!!

BUT IT IS STILL MAGNIFICENT, in that each 5hr 20 min, I turn in 2 WU's ..... which is EFFECTIVELY ... what I said (but not QUITE the same !!!!!)
Apologies!
