Hungry hosts could be a problem to Einstein?

Hello everybody. I brought

Hello everybody.
I brought some rigs along to crunch Einstein with my GPUUG buddies whilst SETI is getting fixed.
I see what you mean about download bandwidth, I just trashed half my 50GB allowance in 2 days.

Cheers from a VERY wet and stormy Hereford, UK.

Not sure but i belive, even

Not sure but i belive, even for 6 hosts in E@H, 25 GB on 2 days is to much, are you sure of that? Something else could be taking a ride at you conection? Did you remember to start with 0 resource share and small number of days in the cache settings? Different from SETI, a 0.5 days cache is a lot here, new WU are allways avaiable in large quantities (someone tells me the E@H limits to 300WU max, must check i´m not sure about this info).

Yes, 25GB is way over for E@H usage, something else perhaps?

Cheers, Mike.

Maybe you know, what is the normal complete bandwith DL+UL used by a normal Einstein WU? Just an aproximate figure will help.

Oooh, of the order of a few MB. We use 'locality scheduling' - making use of what you already have - precisely to reduce the ongoing bandwidth loads.

Download : what happens is that you get a 'loaf' of data which is then sliced as the days go by. For first attachment ( or re-attachment after some long break ) to E@H you also get quite a number of smaller data files as a once only ( in addition to executables which are varied occasionally ). The individual WU's are instructions to slice off from a particular part of the loaf that you probably already have - the server keeps track of you and your potential wingmen here - unless that loaf is used up in generality by the project. In which case you get another.

Upload : is a rather more compact results file.

Gary/Oliver/Bernd - what figures would you give?

Cheers, Mike.

I need to run out the door, but I posted on this topic a year ago in the thread I pointed to earlier.

Here is a link to the relevant point in that thread.

With this numbers lets make

With this numbers lets make some calculations:

Is something about 16 MB (8 x2MB) for each 1 1/2 hour WU (the average runing time with 2WU at a time on each GPU on this destroyer with an I5 and 2x670 GPUs) close to 11 MB/hour, about 0.25 GB/day for a normal average host not a top one.

In a battleship with 2x690 running 2 WU on each sub-GPU, with the same average time to run that goes to about 1GB/day. Or more on a big battleship with 3x690 super-crunchers some mates have.

That could be realy a problem for some mates how have a limited usage quota of their conection if they try to put to much hosts to work on that conection.

But they are cleary far from 25GB in just 2 days in a 6 mixed fleet.

Could anyone else verify the calculations, sorry i just in the middle of a few beers drinking task.

Cheers!

Well done, I stand corrected. Of course it depends on the number of hosts your running .... :-)

Well, I was away from home

Message 113100 in response to (parent removed)

Well, I was away from home and it just kept downloading thousands of 2MB tasks.
I got the emails from ISP, 50%
75% then today 100%. I had to buy an extra 5GB. Got 8 hosts on it now.
My cache was set to the max.

Just checking the project

Just checking the project folder and I have about 2000 tasks remaining and quite a few are 8MB !
