1) Message boards : Number crunching : Collab and Suspending GPU (Message 143184)
Posted 20 days ago by Dr Who Fan
I think Google is messing around with it!

My Google Colab (free version) has been been acting very weird lately. For me, on and off about the last almost two weeks. Here is what I have been experiencing:
* Suddenly last week it won't let me run my Wu-Prop NCI project concurrent with any other projects though nothing has changed in my code / images that have been successfully running it past many months.
* No GPU instance available or if I get a GPU instance the session only runs for 1 to maximum of 3 hours before stopping
* CPU only instance normally are running about 6 hours.
* CPU + GPU instance hours now vary all over the place but no more than 4 hours before stopping.
*Recently I had a CPU ONLY instance running for almost 13 hours on the SR5/SR Base project before stopping.

Amazing story!

Child with Fractured Skull Grew Up to Be ‘Fastest Human Calculator’
Twenty-year-old Neelakantha Bhanu is known in India and all over the world as the “world’s fastest human calculator,” but it was not always this way.

... The doctors told Bhanu’s parents his brain function could be impaired for the rest of his life due to the head trauma.

Okay can someone please explain in simple terms what this means?
EVERYTHING YOU NEED TO KNOW ABOUT "2+2=5". As a former mathematician, I have things to say.

Here are some interesting things from a Wikipedia article about the number.
Popularity and litigation

The song, released in late 1981, initially gained popularity on the American West Coast in January 1982; many who had the number soon abandoned it because of unwanted calls.

I have decided my favorite is 8675309, since it's probably the largest prime number that literally millions of people actually remember. Even if they don't know it's prime. :)

For those that are younger than a certain amount of time... Jenny's phone number

Getting HTTP 500 errors when trying to upload completed work. Is this due to heavy load on the server?

And within the last hour AT&T is not connecting to Streams ISP and based on the tracert it is stopping at the same place as last time (ATT'S) gateway to the internet backbone.

Anyone else having connection issues to Streams BOINC project server?

Just tried another on-line tool since the web site is still unreachable from my home PC's and my cell phone provider *VZW / Verizon Wireless) networks.

On line tool shows lots of routing errors "ICMP error: 410"> https://www.dotcom-tools.com/online-traceroute-network-latency-test.aspx:

Thanks for your help Stream. I have opened a support ticket with my ISP (ATT) pointing them to the forum posts here. Doubtful that they will be of any help, but you never know.

Will let BOINC keep automatically trying in the meantime.

Stream,
Strange things happening. Again yourweb site is unreachable and BOINC can't reach site to upload/download files again for about the last 2 3/4 hours from my home internet connection.

Looks like my ISP (AT&T) gets "lost" after it leave their main backbone (hop 5) to the rest of the internet from my home network:
Tracing route to proxyma.dyndns.org [37.147.151.28]
