Assuming you have permission to run BOINC & BOINC-based applications on what would appear to be a "company owned and managed" computer you will have to ask for the Rossetta servers to be white listed on the corporate firewall and any associated security applications that may be running. It is not unknown for firewalls to allow an "initial sniff" of data through from an "unknown" source, then to pull the drawbridge hard and fast once a lot of data is being transferred.

GPUUG are one of he most consistent donors to SETI@Home, and for that I am grateful.
The best place to see what you can do to help SETI@Home is to ask the question on the SETI@Home boards.

A few answers:
1 - The BLP gets its data from a number of sources. The biggest amounts are from the Green Bank Telescope in the USA and the Parkes Telescope in Australia. As far as I'm aware they do not use the big telescope in China or the Arecibo telescope as neither is very good when it comes to collecting data from a single point in the sky as neither is "fully steerable". Also it collects some data from various optical telescopes for "Optical SETI".

2 - Undoubtedly as the instruments get more sensitive and analysis techniques improve more solar systems will be located.

3 - If you are asking about SETI@Home, and how many FLOPS per hour per user then the best place to ask the question is on the SETI@Home forum - this forum is for non-project specific questions.

4 - The 64 GTX1080 GPUs are used to gather the data from the telescope receivers. An individual is probably more than welcome to provide the money for another receiver interface computer, but the cost isn't only the $$$ for the GPUs, but also all the RF hardware, the software required to run it all, and the data interfaces to those performing the analysis.
Errr - where do you get the "40% of the processing we do" from. If one is talking about SETI@Home then 64 GPUs is a very small fraction of the total processing power of that project.
What do you mean by "Can we have faith in that?"?

David Anderson is, as far as I'm aware, doing OK, he's involved in a number of projects based at the UCB Space Sciences Lab.

And, as ever, money is tight for the majority of science projects.

Byron - the last time I saw this sort of thing was a GPU that was suffering from old-age. Given that you K4200 is probably about 4 or five years old it may be heading for the Great GPU Graveyard :-(

The clue is in this line:
Running as a daemon (GPU computing disabled)


The Windows drivers used when running as a daemon do not (by default) support the use of an nVida GPU for computational use. There may be third-party drivers that do
The only solution I can think of (and admit that this may not be a route open to you) is to re-install BOINC in non-service mode, but then it will only run under the installing user account.

Hi - there are a few ways to achieve what you are asking....

1a - You will have to "play" with your cache settings, these easist are accessed from your SETI account home - reduce the number of days cache and the additional days cache from the defaults - it will take some attempts to get it right, and give it at least double the cache size to settle down.

1b - This is different to the cache setting. In the advanced view of the BOINC GUI go to options, then "computing preferences", this will bring up a window with a number of tabs, one of which is "computing", on that tab you will see a line something like "use at most x% of CPUs" - reduce x% from its default of 100% to the fraction percentage that gives you the number of core you want to use (each core in use equates to one task being run concurrently) - for example if you have a four core machine and want to run two tasks at a time set x=50%.

2a - Not very easy, but you can set daily schedules for both computing and network activity using the "computing" and "network activity" tabs (above).
One trick is to setting a start time of 20:00 on day one, and an end time of 08:00 on day two will allow activity between 8pm and 8am, and nothing in between - which can be very useful for those with very expensive day-time power, or very high daytime temperatures....
If you use the "download" size limit it is worth knowing that a "normal" task is just over 700kb in size, and an AstroPulse task is about 7Mb. For both the returned file is somewhere between 20 and 35kb in size.

2b - If you happen to be looking when a task finishes you will see the icon blink for a few seconds. But generally using either the fully automatic, or scheduled automatic will look after things without you having to worry too much.

3 - There are a whole load of logging flags, again accessed via the advanced view options, but this time the "event log options", I think the only ones you want set is "task" (but the transfer one can be useful when looking to see what has come and gone...)


I hope this helps - as you can see there are lots of options, and I've only scraped the surface with the ones that don't need you to manually edit files (which can be a very risky operation)

All the uploads that were stacked up have finished, but still some stuff to report.

BOINC detects "usage" as mouse of keyboard inputs, thus won't detect using, say, the microphone or camera in a video conference doesn't count as "in use".
One possible solution is to make BlueJean an excluded application within BOINC, so suspending activity while taking part in a video conference.

That all depends on the time it lands on your doorstep.
30 minutes from bare-board to working system, so say an hour including stripping the old one.

There is a discussion about this on the Collatz forum:

However, I've just run a task to completion which uploaded a few seconds later so the malady may have been cleared.

...particularly where those sites and users are spread over a large number of servers in a large number of countries.
Also, as each project is administratively independent of BOINC it is the responsibility of each individual project administrator to ensure their appropriate level of compliance, not that of BOINC, which in itself does nothing apart from co-ordinating the processing on the users' computers, and as far as the projects are concerned they do not have a "direct connection" with "BOINC Central".
The only part of "BOINC Central" that has any need to consider the implications of GDPR are these forum.
