1) Message boards : AP26 - AP27 Search : AP27 Closing??? (Message 134131)

I have dreamed about WSS search coming back! To me that is the ultimate conjecture, where a prime of this form has not even been proven to exist yet. Actually finding one would be simultaneously become a proof.

I am looking forward very much meeting mattozan and his lady in a couple of weeks as part of this.

As are we!

Ahh ok. I'm slowly getting all of this... I never knew you could login remotely via the BOINC client


eFMer is a tool you can use to connect, monitor and control multiple BOINC instances simultaneously, both local and remote. If you are running multiple machines, it's helpful for getting your BOINC info all into one dashboard.

Run times are up significantly ... for some units, I am now over 6000 seconds with FFT @ 280k. When we first started the challenge, I was around 4000-ish.


My instances at Vultr and Google are all in the 4000's

I now have three "Trogdors" burninating through some workunits!
--Tim

Burninating the countryside! :)

I burned through my Digital Ocean credit during the Lennart Vogel Honorary Challenge, and now I'm burning through the Google Compute Cloud credit (USD$300!), along with some speedy permabirds leftover from the Lunar Challenge.

I tried and failed to get IPv6 working from my house, to talk with an IPv6 Vultr instance that I have. My ISP won't support it, turns out...

@MichaelG, I took this opportunity to look at my Firewall settings at Vultr, and saw that they weren't enabled since my last move. Corrected now--thanks!

This is a startup script that I adapted from 98golfer for use at Vultr. I just used it at the Google Compute Engine, and it works there too. I think I used it successfully at DigitalOcean two challenges ago, also.

Prereq #1: Have to use a debian image
Prereg #2: You need to put your own PrimeGrid Account Key where indicated below
Prereq #3: This uses wget to pull a customized global_prefs_override.xml, gui_rpc_auth.cfg, cc_config.xml, and remote_hosts.cfg. These aren't *required*, but can be used to log in remotely with the BOINC client to monitor and adjust WUs. If you want to do this, you'll need to put your files somewhere and then insert that URL path where indicated below. I host mine in dropbox, as you can see, but use whatever you have.

#!/bin/sh apt-get update apt-get -y --force-yes install boinc-client cd /var/lib/boinc-client/ rm global_prefs_override.xml wget https://www.dropbox.com/<YOUR PUBLIC PATH>/global_prefs_override.xml boinccmd --read_global_prefs_override boinccmd --project_attach http://www.primegrid.com/ <INSERT YOUR PRIMEGRID ACCOUNT KEY HERE> rm gui_rpc_auth.cfg rm cc_config.xml rm remote_hosts.cfg wget https://www.dropbox.com/<YOUR PUBLIC PATH>/gui_rpc_auth.cfg wget https://www.dropbox.com/<YOUR PUBLIC PATH>/cc_config.xml wget https://www.dropbox.com/<YOUR PUBLIC PATH>/remote_hosts.cfg boinccmd --read_cc_config service boinc-client restart boinccmd --project www.primegrid.com update


No muss, no fuss. I just hit "Create" for the VM with this script entered into the right place, it runs automatically when the instance is ready, and the host just shows up in PrimeGrid and starts downloading WUs based on your defaults! I can't imagine Vultring without it.

Yeah! I've got a full set of Ruby LLR:

Looks so good! It's always that last SoB which you have to wait for...

Finally cooled off here in an autumn-snap. Brought both rigs back online after being dormant since around April. One of the fans on a AMD Radeon R9 card immediately started rattling (this is the lone remaining fan, mind you--the other one on that card died last year, despite my attempts at repair). Then I remembered that it had actually gone wobbly just before I mothballed it, and also remembered thinking "I have to replace those cards before next winter."

So I'm thinking of replacing these two gimpy Radeon R9s with GTX 2060s? Thoughts? Seem like good bang for the buck. I see that the 2080's are about twice as speedy, but also twice the price. >$1000 to replace both cards might be a bit out of my fiscal comfort zone.


What about the 1660 ti's (um if that's the right model). If I remember those are pretty and not nearly as expensive.


Interesting. I see that the 1660 Ti does quite well on PPS-Sieve, better even than the RTX 2060. But on AP27 its performance lags behind the RTX 2060. And on GFN, the RTX 2060 seems to do progressively better than the 1660 Ti the bigger the WUs.

For a difference of ~$100, I think I'm inclined to go with the RTX 2060 over the 1660 Ti, just to future-proof against larger and larger GFN WUs in the upcoming years.
