POGS Skynet...

Started sending out work again on the 19th. On the morning of the 20th, I saw that their servers weren't responding. The whole POGS system is down (not just the BOINC portion) although the main Skynet site is up and appears unaffected.

I am guessing a serious crash at this point being out of commission for almost 2 days now... (When are they going to finally equip servers with air bags??)


Hey guys,

That's correct the NFS server had a complete meltdown over the weekend, (something about not enough beer) Kevin is currently on the scene and attempting to resuscitate it.

If all else fails we have regular backups so we will be back soon.

For smart TV features I use a chromecast, cost a whole $45 so not too concerned about future proofing and allows me to play pretty much anything I want on the TV using my phone as a remote.

ASAIK HTC don't yet pre-install it but they have branded their own application around BOINC. http://www.htc.com/au/go/power-to-give/.

AFAIK Win 10 Mobile supports ARM devices and i386 devices so both the boinc client and any application executables would need to be compiled for those devices. Which in theory is possible.

Hey guys,

Just looking at moving theSkyNet POGS onto the newer precompiled wrappers, from http://boinc.berkeley.edu/trac/wiki/WrapperApp and ran a quick virus scan using virustotal.com. Where it found that 4 of the scanners are detecting a trojan in the wrapper_26011_windows_intelx86.exe file.
see https://www.virustotal.com/en/file/b303fd5cf67c2132f3c188888777f05dd05cdf91c09f97cb0c3dab76fdbf6d68/analysis/ for more details.

I imagine it would just be a false positive but as we'll be pushing this out to clients we wanted to be doubly sure. Does anyone know one which machine the wrapper was compiled on and can verify that the machine is clean?

Cheers

I couldn't agree more.
We try our best to respond to people as fast as possible and will always try to provide direct feedback to our users as to what their computer is doing. At theSkyNet POGS for example we can show an image for every galaxy your computers have worked on and even highlight which section specific section of the galaxy your computer is responsible for processing.

Hey ChristianB

Have you had any feedback from David?

Also can you provide anymore information on what is wrong with the HTTPS config on the server and I'll see what I can sort out.

13) Message boards : Documentation : Recent Average Credit description incomplete (Message 55640)
Posted 27 Aug 2014 by eckley
Post:
Hey,

I realise this thread is a little old now but I was looking for the same information and thought I'd share what I found.
Apologies for the fairly long winded explanation you can skip to the bottom for some example graphs.

Credit is awarded by the code in this file sched/credit.cpp
Specifically were interested in the grant_credit function (starts on line 52). The users RAC is updated on line 79 with the following command
    update_average(
        now,
        start_time, credit, CREDIT_HALF_LIFE,
        user.expavg_credit, user.expavg_time
    );

The CREDIT_HALF_LIFE is defined in sched/sched_util_basic.h on line 32.
#define SECONDS_IN_DAY (3600*24)
#define CREDIT_HALF_LIFE  (SECONDS_IN_DAY*7)



We can find the definition for this function in the lib/util.cpp file on line 238.

// Update an estimate of "units per day" of something (credit or CPU time).
// The estimate is exponentially averaged with a given half-life
// (i.e. if no new work is done, the average will decline by 50% in this time).
// This function can be called either with new work,
// or with zero work to decay an existing average.
//
// NOTE: if you change this, also change update_average in
// html/inc/credit.inc
//
void update_average(
    double now,
    double work_start_time,       // when new work was started
                                    // (or zero if no new work)
    double work,                    // amount of new work
    double half_life,
    double& avg,                    // average work per day (in and out)
    double& avg_time                // when average was last computed
) 


Which, if you don't like the complex math in the source code, can be summarised as:
#First calculate the weight value 
weight = 2^[ -1 * days_since_last_update/7days ]
#then determine which function to use
if weight is approx 1 (this occurs as days_since_last_update approaches 0.0)
new_avg = old_avg * weight + ln(2)*new_credit/7days #the math here is a little more complex
else 
#this is the main function and will be used most of the time
new_avg = (old_avg - new_credit_per_day) * weight + new_credit_per_day


To help visualise the weight function I've graphed it here http://www.wolframalpha.com/input/?i=plot+2%5e(-x%2f7)+from+x%3d0+to+10 where x is the number of days since last updated.

If new_credit_per_day == 0 the above simply becomes
new_avg = old_avg * weight

Which gives your standard exponential decay.
If new_credit_per_day less than old_avg you get exponential decay to the new_credit_per_day value.
Finally if new_credit_per_day is greater than old_avg you get exponential growth towards the new_credit_per_day value.

for example: (where x is number of days)
Graph starting at 1000 RAC with no new credit
Graph starting at 1000 RAC with 500 new credit each day
Graph starting at 1000 RAC with 1500 new credit each day

This process is performed every time a user is granted new credit for any reason otherwise it is updated at least daily by the update_stats background task.

Hope this helps someone else :)

For me, Yes to both.
1) An option to mass hide posts would be nice.
2) The ability to delete posts without going through the DB would be useful as well. Although as you say it is possible to delete straight through the DB, I just like to avoid directly modifying the DB on production servers.

Also the combination of setting the Akismet key and limiting new members to only post in a single forum has really helped out on theSkyNet.

That's a really interesting idea, I imagine there are a host of computers sitting idle in stores. I wonder what this would do to their electricity bill though.

Hey,

I'm new here so someone more experienced might be able to jump in as well, but I had to figure this out for our project (http://www.theskynet.org).

You can make a call to /project/lookup_account.php with the get params email_addr and passwd_hash where passwd_hash is a MD5 hash of your_password + your_email. Note your email must be lower case.

This will return an authenticator that you can then use with /project/am_get_info.php with the get params account_key set to the authenticator returned by the first call.

This will then return all your account details including your user id.
more details at http://boinc.berkeley.edu/trac/wiki/WebRpc
