The studies are almost done. We only lack 300 jobs. We will then do post analysis to determine where there is more work needed. This will be about 8* 28'000 1'000'000 turn jobs."

so.. 300 more jobs.. so.. are we multiplying 8x28000 to get 230,000 work units?

I'm not the LHC Alex. Just a number cruncher like everyone else here.

>>are we multiplying 8x28000 to get 230,000 work units?

That's the way I read it.

It's about a week's work, on recent performance.

I wonder what will come after that.

This are 230'000 jobs not WU's.
How I unterstand the 'BOINC-terminology' here at LHC:
1 job is equal with 1 result, which is distributed to 5 clients. For that 1 job cotains 5 WU's.

So we can calculate with 1'150'000 WU's!

And with LHC's ever growing membership (13240 when I last looked) this will last us...oh...about ten days! :-))

Terminology:

1 job ~ 1 wu (maybe more if we resubmit jobs to finish fast)
1 wu ~ 5 results (maybe more if deadline is surpassed)

1 result = 1 computation on a client.

It is confusing that a result is called a result before it is actually a result, but that is the BOINC naming convention.

Okay now it is clear.

I mixed this 'BOINC naming convention' (1 wu ~ 5 results) in the wrong direction. I mixed the word WU and result, but now it is clear.

For that I correct:
So we can calculate with 1'150'000 results!

@MikeW
yes, thought that too... 'Maybe work for 2-3 weeks' .. as long as the last study was.

We are fast, but not that fast ... these are the 10 hour Results. So, you are looking at 11 million hours of compute time. Willy shows about 26K hosts, rounding up shows 30K hosts ...

11,500,000 / 30,000 = 383 CPU hours per host

I run 5 projects so, I will have work for about 1915 hours ... of course this asumes that all work runs to the full time ...
