The project http://boinc.vtu.lt/vtuathome/ is a test project. It is developed to test the BOINC platform and to learn the BOINC API. The project is still incomplete and your notes, suggestions and comments are appreciated.

The aim of the project is to count the quantity of prime numbers in a large interval. The worst algorythm is used, as we need a lot of computing hours and many workunits. The client side application gets the beggining and the end numbers of the interval and divides every number from this interval by every number from 1 to it self. As we know there are better algorythms:

1. To divide the current number only by every number from 1 to sqrt(itself);
2. To divide the current number only by every known prime number from 1 to sqrt(itself); This one is the best known algorythm. In some modifications division operation can be changed into some set of sum operations.
We have some plans for future:

1. To use the platform to solve a wire bundle parametrical optimization problem
2. To use the platform to solve medicine research problems
3. To use the platform to solve any interesting suggested problem. Your suggestions are also appreciated.

今天翻出这个项目来想算一个任务包
本来预计40分钟完成的任务包,算了6个多小时后进度还是0,剩余时间也从来不变,终止之...

白白浪费六个小时运算能力!

这个项目我也算了,确实很不稳定,测试项目最好还是谨慎参加的好

现在好像改成了[url=http://boinc.vgtu.lt/vtuathome/],是测试BOINC平台的项目。目前没有工作单元,但根据新闻来看将会有包。
Test problem (#4) solved!
The key has been found by [AF>WildWildWest] lamoule from L'Alliance Francophone team. Congratulations! Our thanks to all participants.
Job generation has been stopped. We wait for all results to return before the purging of database and start of the new test.
With best regards,
The Project Team.

大意:#4系列包已经解决完成,分析现有数据后将开始新一轮发放。

Start of the project
Dear All,

We would like to announce some kind of reincarnation of VTU@Home project. Some of you may remember that project, which was created in 2006 by Aurimas Norkevičius (VGTU postgraduate student at that time). Over that time, several different applications in various fields were developed in VGTU Department of Mathematical Modelling. They have gained significant attention from BOINC volunteers. Project had almost 3.500 users, which was actually on the top of capabilities of available server. However, in late 2009 due to hard drive failure, all project data were unrecoverably lost… and we had no technical and human resources to continue.

However, after two years, we have decided to recreate our BOINC project. We believe that in volunteer computing there is a place for true Olympic principles and spirit, and so we hope to find a place for our small academic project among the others. We start with cryptographic applications and hope to find scientists from our university and other Lithuanian academic institutions interested in solving their problems using this computational platform. In any case we believe that our project can contribute to popularization of ideas of volunteer computing in VGTU community.

At this point, we would like to thank the users of VTU@Home for their contribution and apologize for the possibly lost work due to hardware crash. Old project’s database is lost. Therefore we do not announce the return of VTU@Home, but the start of “VGTU project@Home”. Furthermore, this project name indicates correctly the name of hosting institution, which was changed some time ago.

With best regards,
The Project Team. 15 Feb 2012 | 17:24:39 UTC
PS:项目已经重启,原先的数据丢失,现在改名为VGTU project@home。

这个项目好像是测试BOINC接口用的,现在依然没有任务包。

We start solution of a new problem. The delay bound of the single job (deadline) has been extended to 7 days.

With best regards,
The Project Team.

2018-03-16: VGTU project@Home, News

Dear VGTU project@home users,

We are constantly working on the current research problem.

Although, you don?t see changes in the client applications (versions are the same), generation of work and assimilation/processing of the results are changed from time to time.

After one of such changes, the bug was introduced into generation of tasks (workunits). We believe that we have fixed this bug in work generator on Monday, March 12. It seems that there are no problems with the tasks/workunits generated since then. However, some older erroneous work units may still be there? We don?t know exactly which to cancel them. Don?t worry, no time is lost: application simply fails to start and generates ERR_TOO_MANY_EXITS error after some number of trials.

The good news is that we have started to write a draft of the paper on the current research using our BOINC project.


With best regards,
The Project Team.

亲爱的算友们:
我们最近正全力以赴地解决当前研究上的问题。
虽然计算程序的改变(即便相同版本号的计算程序也有所改动)、每一代的任务包的改变、计算结果分析的改变都没有明显到让各位都察觉到,但我们确实在时时改进着项目。
在引入某项改进的时候,这项改进给任务生成程序带入了一个bug 。我们确信在本周三(3月12日)已经将此bug修复。看起来从那以后再没有出现与任务生成相关的问题。不过,那些已经产生的错误任务包仍然存在,而且我们暂时还不知道如何干掉他们。请不要担心,这也不会浪费各位的处理时间,计算程序在开始计算这种错误包的时候会直接出现“ ERR_TOO_MANY_EXITS”错误信息。
好消息是我们已经开始起草一篇关于项目研究成果的文章了。
以上
