Bug#636075: boinc-client: Boinc is (too) disk intensive

[franckr]

Hi Kevin,

You probably posted as same time as me above.

3 points I disagree with you:

1. Clean Energy project system requirements do NOT state the high disk transfer.
It just mention the large disk space needed (2Gb).
(so nothing to see with the up to 2.9Gb/hr I found)

Ref: When selecting projects in "My Projects" (https://secure.worldcommunitygrid.org/ms/viewMyProjects.do)
there is a link near Clean Energy project stating "Please review the system requirements before opting to participate in this project"
I stored this link in system_requirements.txt
I don't see the disk transfer in it.


2. Boinc should control (1) your project and (2) where the data are saved
See my <3> in previous message.


3. I never had 3 workunits running in parallel.
I don't know why above shows like that (3 "in progress" = another bug ?, or because I aborted units ?), but I only have one dual core, so max 2 units runs in parallel.
But you are right, I don't remember having seen 2 workunits from Clean Energy project running at same time.

I do agree that further discussions specific to WCG should happen on WCG Forum.

Thanks, 
Franck

System Requirements

    What are the recommended minimum system specifications?
    How much data will I download and upload while participating with World Community Grid?
    How do I know if my computer is running the 64-bit research application?


What are the recommended minimum system specifications?
In order to participate in World Community Grid, you will need to have at least the following:

    The ability to display graphics (if you wish to see the graphics)
    An Internet connection

In addition, each research project has its own requirement for memory and disk space. These are as follows:

Research Project 	Memory Available 	Disk Space 	Operating Systems
Computing for Clean Water 	400 MB 	100 MB 	Windows1,5, Mac, Linux3,5
The Clean Energy Project - Phase 2 	1,024 MB 	2,048 MB 	Windows1, Mac, Linux3,4
Discovering Dengue Drugs - Together - Phase 2 	1,024 MB 	250 MB 	Windows1, Mac, Linux3
Help Cure Muscular Dystrophy - Phase 2 	64 MB 	50 MB 	Windows1, Mac2, Linux3
Help Fight Childhood Cancer 	250 MB 	100 MB 	Windows1, Mac, Linux3
Help Conquer Cancer 	250 MB 	50 MB 	Windows1, Mac, Linux3
Human Proteome Folding - Phase 2 	250 MB 	100 MB 	Windows1, Mac2, Linux3
FightAIDS at Home 	250 MB 	100 MB 	Windows1, Mac, Linux3

1. World Community Grid supports the following Windows platforms: Windows XP, Vista, 7, Server 2003, Server 2008
2. For these projects, only Mac computers using Intel processors are supported
3. Only Linux on x86 and x86-64 is supported
4. Users who choose to run this project are encouraged to set the 'Leave applications in memory while suspended' option in their device profile
5. 64-bit application available

How much data will I download and upload while participating with World Community Grid?
The amount of data that you transfer depends upon how your processing preferences are set to run, how powerful your computer is and how often your computer is on. It also varies based upon which research projects you run on your computer. An average computer contributing to World Community Grid returns about 2 results per day.

Each of the research projects at World Community Grid uses a different application, input files and output files. As a result, the size used for each of these varies by project. This is outlined on the chart below. Please note that the data is compressed during transfer and is decompressed after it has been downloaded. As a result it will occupy more space on disk than the numbers shown below.

Research Project 	One-Time Download 	Per Workunit Download 	Per Workunit Upload
Computing for Clean Water 	10 MB 	0.001 MB 	0.5 MB
The Clean Energy Project - Phase 2 	200 MB 	0.1 MB 	20 - 80 MB
Discovering Dengue Drugs - Together - Phase 2 	10 MB 	1-20 MB 	1 MB
Help Cure Muscular Dystrophy - Phase 2 	0.7 MB 	0.1 MB 	0.2 MB
Help Fight Childhood Cancer 	1.0 MB 	0.1 MB 	0.1 MB
Help Conquer Cancer 	1.0 MB 	0.1 MB 	0.1 MB
Human Proteome Folding - Phase 2 	12.0 MB 	1.5 MB 	0.1 MB
FightAIDS at Home 	1.5 MB 	0.1 MB 	0.1 MB

How do I know if my computer is running the 64-bit research application?
On a Windows machine, you can use the Windows task manager to view the process name. 64-bit research applications will end with "windows_intelx86_64", while 32-bit applications will end with "windows_intelx86"



On a Linux machine, you can find the PID of the research application (which will start with the name "wcg") and then execute the command "file -L /proc//exe"

There is no 64-bit research application for Mac machines at this time.
