hi all.

after i create a project and add an application to the server, i have to craete work for clients.

my question is:
if i use the create_work command for one time, is the generated workunit represent the whole work and i will have the results to my App. or i have to build a work generator and craete more workunits to get the work done.

my question is about the concept of workunit in boinc when it is in action (i have read the definition of workunit) but when i saw the grid running on a test application, i confused.

thanks.

Hi all.

Can any one help me to develope my application from begnning to end?

let's say we want the application to search a space consist of 1 trillion choice by trying them one by one, for example:

int c=?;
for(int i=0;i<1000000000000;i++)
{
if(c==i)
finish();
}

if i would to divide the work to 1000 task :
1.how would the boinc workunit templete file be?(parameters values???)

2.what is the code that i have to write in my application?

please someone explain that to me, to understand and make my own applications.

thanks.

thanks Ageless for your help.

i knew the links that you have puted and i have read them before.

I will explain the whole thing. if I have this code for example:

for(int i0=0;i0<1000;i0++)
{
do_computation();
}

and i want to divide this work to four workunits or tasks (each one 250 iter), how i determine that to server???

I meant exactly what I said.
The handful of developers have their own area, and don't normally read the posts on this site. Most of the problems posted here are just routine, and get answered by other BOINC users.

I'm not interested in developing my own project, so I don't know much about doing this.
Some questions may take days to get an answer. It depends on who knows it, and what they're doing with their life at the time.

edit
Judging by this thread, the error may be some sort of time limit for how long the WU was allowed/expected to run.

thanks a lot my friend.
I am student and I am working on my graduate project,I dont have much time so dont blame me for my posts.

thanks again.

Please don't expect instant answers. The people who post here are are mostly just other BOINC users, and don't necessarily know the answers to all questions.
And not everyone is in the same part of the world as you, and awake at the same time as you.


ok.thanks and i m sorry for westing your time.

but what did you mean by:

Dear Mrs/Mr

I m trying to build a grid computing platform using BOINC, briefly I configured a boinc server using the VM image on BOINC website, I created a project using the documentation.

Now I m developing my application which is Cracking DES-56bit, but I have some problems that my work units returned with an error 177 (rsc-limit-exceeded).

I have some questions, please help me:

1. How Boinc server divide the whole work into tasks, I mean where did specify the rang to my client, for example, in my application DES_Cracker (start_key,end_key).

It looks that boinc applications code is sequential, so where the dividing is made?

2. What are the role of the workunit template file and what's the relation with the dividing of work into tasks. How can I calculate the following:

<rsc_memory_bound> </rsc_mem_bound>

<rsc_disk_bound> </rsc_disk_bound>

<rsc_fpops_est> </rsc_fpops_est>

<rsc_fpops_bound> </rsc_fpops_bound>



And are they calculated for the whole application or for one job for the client???



3. does The workunit represent the whole work of the application or it is a part of it?



There are another question about create my own work generator and Validator…



But now I really have to know the answers of the main previous questions.



Please help me…



And I will be thankful for replying me.

Sincerely.
