1) Message boards : News : Repealing Net Neutrality Could Affect MilkyWay@home (Message 66838)
Posted 3 days ago by Jake Weiss
Hello Everyone,

On December 14th, 2017, the Federal Communications Commission (FCC) plans to take a vote to remove the Title II classification of Internet Service Providers (ISPs). In effect, this will remove the FCC's authority to enforce the doctrine known as net neutrality. Net neutrality is the idea that all traffic on the Internet, regardless of its origin, should be treated equally. This doctrine is responsible for the massive success of the Internet today. It allows any company, institutions, and individuals to host their own websites and web services without the fear of having their web-traffic throttled to accommodate another company, institute or individual who has more money to pay for their traffic to be prioritized. It also prevents ISPs from throttling or being paid to throttle websites for any reason, such as, political, or ideological reasons.

Why is this important for MilkyWay@home? As a research group that survives off of donations from our wonderful volunteers and government grants, we do not have the means to pay for things like paid prioritization, or any other potential ransoms that ISPs may decide to charge in the future to transmit data. This could lead to a decrease in our workunit availability and overall reduction to our abilities to make discoveries. The repeal of net neutrality can also lead to new fees for our volunteers. For example, ISPs will be allowed to sell access to certain websites as part of "bundled" packages. This means to receive workunits from us or any other BOINC project, or visit our websites, you will have to buy into a "bundle" that includes our or other BOINC websites. In our minds, this is not a partisan issue as there is overwhelming support for net neutrality from both parties, (76% of Americans, 81% of Democrats and 73% of Republicans). [1]

If you live in the United States and would like to help protect net neutrality, the best thing you can do is contact your congressmen and senators to let them know how you feel about net neutrality, why it is important to you, and why they risk your vote in future elections if they do nothing to protect it. Additionally, if you would like to help fund larger efforts to prevent the repeal of net neutrality or if you live outside of the United States and would still like to help, consider donating the Electronic Frontier Foundation or the American Civil Liberties Union to allow them to cover the costs of the looming legal battle.

Thank you all for your continued support and I hope for everyone's sake network neutrality can be saved.

I made a 9 and 10 year badge today. They should be released tomorrow, just waiting for a chance to see Sidd and Heidi to make sure they think they look good.

I also checked to see if we need a new credit badge, but we are still a couple billion credits short of needing that.

Hey Adrianxw,

I think that's probably a database hiccup. We've been having a few of those recently and I am looking into ways to prevent them.

Thanks for the report,

Hey everyone,

I noticed some database instability this weekend. I'm going to update some server applications to try to fix this. If you notice any issues over the next couple days, let me know.

Hey dgd3,

I don't see any tasks crunched by your computer. Any chance you can run a couple and let me know what errors you are seeing?

They've been running for a couple weeks now. I just wanted to put this here because I know there is a tradition of putting up broken runs before a long weekend. I actually stayed an hour late today to make sure everything was running smoothly before the holiday.

It looks like all the runs have reported a few successful results now though so I'll be heading home soon.

Happy Thanksgiving,

Jake

Hey Everyone,

Just noticed some issues with the work unit generator. Working on it.

[Edit]

Was a quick fix. I'll keep an eye on things for the rest of the night.

Posted 26 Oct 2017 by Jake Weiss
Hi,

We currently do not support the open source AMDGPU drivers. Getting the client working on AMDGPU is on my list of things to do, but it has taken the back burner to a few more important tasks recently.

Sorry,

Yes, it seems like it is functioning normally now. It is common to have 70+ results waiting for validation as each workunit it crunched 2-3 times each to ensure no one is running faulty hardware or trying to cheat for credits. I see you do have one mistakenly marked as invalid. This must have happened in the weird in-between period after I told the server to revalidate those types of workunit. I'll have the server revalidate that one tomorrow.

Hey HassanShebli,

I just checked all of those listed workunits. It seems the workunits that is still waiting to validate is de_modfit_fast_19_3s_146_bundle5_ModfitConstraintsWithDiskandUpdateStreams_1_Bouncy_3_1508646134_281802_0.

I can confirm this one is just waiting for its sister result to return to check your answer against.

Hey TimeRanger,

I just got the validator fixed. I've tested it on a few workunits and I watched it validate them. I'm going to go ahead and try to come up with a query to tell the validator to recheck all validation inconclusive workunits as well as workunits that were errored for running too many runs. You should see a massive validation run here in a few minutes and you should see retroactive credits even on dead workunits.

As a note some units which we cancelled over the last couple days still will not validate as they were cancelled before a consensus could have been reached on the correct answer.

Hey Ulrich,

I'll keep an eye on those two work units. It might take me a while to figure out why they aren't validating.

Sorry,

Hey Everyone,

I just wanted to give you all a quick and more technical update on what we have been dealing with over the last week.

Our project has been running for upwards of 10 years now and we have been crunching literally billions of workunits over those years. As a result of all of your hard work and dedication, we have actually calculated enough results that we have run out of room to store the IDs of all of these results in a normal unsigned integer value (the default data type used for storing IDs in BOINC databases). As a result, on Tuesday night, I updated our database to be able to store IDs in a much larger data type to prevent this issue from happening again during the remaining life of the project. As a result, I also had to quickly patch the BOINC code we run on the server to allow it to use this newly available data type in the database.

During this process, I missed one of the foreign keys that refers to the results, specifically in the validation process. This led to an issue in validation of work units over the last couple days. I had trouble diagnosing this issue because before the workunit queue clear, everything was running fine however, after the workunit queue clear, when new work with large IDs was being returned, it silently failed to validate workunits.

I have implemented a fix for this last issue and my hope is that things will be smooth sailing from here on with regards to this issue. Of course, there is always the possibility I missed another bug in this pipeline, or I might realize I need to force validation on workunits received over the last couple days. In any case, I will be watching the server pretty closely over the next couple days to make sure its running correctly.

Sorry for all of the trouble over the last couple days and I hope you all continue to support the important research we are doing into the future.

Jake
