11) Message boards : Number crunching : Google Colab and its free GPUs (Message 139692)
Posted 44 days ago by Dr Who Fan
Have been using the Google Colab on and off for about a month now to run PrimeGrid and the last week it automatically "times out" with message it is stopped "due to Inactivity" after about one to two hours.

I know it's free to use... was wondering if there is anything I can do to keep it up and running for more than a hour?

On a related question how can I also attach my WuProp account along with PrimeGrid if I can get it to stay active for more than 6 hours at a time?

When does the 29th Mountain stage start for PST?

PST is UTC - 8 Hours.
You will subtract 8 hours from the start time 00:00:00 UTC on Feb 29...
Which equals 16:00:00 / 4:00:00 PM PST on Feb 28.

Most communities do trick or treat the Saturday or Sunday before October 31st.

Not in Texas - still Oct 31st.

Many communities around me have "guideline hours" where they recommend trick-or-treating like 4 PM to 8 PM. They would prefer the "little ones" not be out in the dark without adult supervision.... etc.

Mu town has a big (free) party at our parks field house for the whole family starting at 6 PM... Games/contest, prizes, and a safe place for the kids to trick-or-treat for candy.

Researchers are performing integer factorization using modified MRAM

...The Purdue/Tohoku probabilistic computer uses a p-bit, which "rapidly fluctuate" between 0 or 1. In a whitepaper published in Nature on Wednesday detailing their proof-of-concept, researchers were able to factor 945 and 35,161 into primes using an 8 p-bit machine.

This is for WAP phones. Anybody here remember what WAP is? (or may be, ugh, even used it? :))

It's absolutely useless in 2019.

https://en.wikipedia.org/wiki/Wireless_Application_Protocol

A WAP browser is a web browser for mobile devices such as mobile phones that uses the protocol. Introduced with much hype in 1999.

Posted 421 days ago by Dr Who Fan
From University of New South Wales: “Maths whiz solves 48-year-old multiplication problem”

A UNSW Sydney mathematician has cracked a maths problem that has stood for almost half a century which will enable computers to multiply huge numbers together much more quickly.

... “More technically, we have proved a 1971 conjecture of Schönhage and Strassen about the complexity of integer multiplication,” Professor Harvey says.
