If anyone is interested in using some Cloud Computing Instances from Digital Ocean, they now offer a $100 credit valid for the first 60 days.


If you use this referral link you will get the $100 credit. - https://m.do.co/c/cd10b71c2e5d


They are fairly easy to setup and use. If anyone here needs a walk through myself or a few of us here on the team can guide you through it.



We recommend the 1GB/3C droplets for $15/month. That works out to 50 cents per day per Virtual Machine. We suggest these particular machines because they are the best value for the money. $5 per core with a total of 1GB of memory which is enough for Primegrid tasks.

Of course, feel free to run larger instances if you choose, but these $15 droplets are the best value.


Also, look for Xeon Gold 6140 CPUs. These have AVX-512 support and speed up LLR calculations when running the Primegrid LLR apps. There is little to no charge to setup the initial VM then check what processor you have then destroy that droplet if you don't get the right CPU. Try again until you get a GOLD CPU. The command you can use at the command line to see your processor type once you login is less /proc/cpuinfo Pressing Q quits out of the CPU Info Listing.

Hey Penguin,
I'm thinking about using cloud instances but I'm not sure about it as I haven't used cloud instances before. Would you still recommend DO? In the case of a "yes", would you guide me through the setup?

My DO account was blocked due to “atypical activity” with 10 droplets running and my response on the ticket has gone unanswered for 3 days. Have in mind that it is not possible to destroy the droplets on a blocked account, and they are still charging my account with 10 not reachable and not running droplets. I regard that as downright unprofessional. I am NOT looking forward to what kind of trouble this can develop into. However I can recommend to be very careful dealing with them upon scouting the net for other customers terrible experience with this provider.

However Google Cloud can almost match the price to performance when the VM is created in preemptive mode, though it requires more babysitting so to speak.

I created an account for Google Cloud for now to test and play around with cloud services. I got some stuff running but it seems like it stops running when I close the ssh browser window. How do I keep running stuff without having the browser console open?

Message 138627 - Posted: 4 Mar 2020 | 16:23:48 UTC - in response to Message 138619.

A few usefull tips on Google Cloud:

I use PuTTY to connect to google cloud or any other VM. Easy to use once you get familiar with it. You can use the same SSH key across multiple instances or beef up the security and create individual keys for each instance and even add another layer of security by applying password on the SSH key.
During creation of a VM click on Management, security, disks, networking, sole tenancy and chose security tab and scroll down to paste the private key you generate in PuTTYgen.

The most powerfull instance ive seen so far is the N2.
When creating a VM click the general purpose tab under machine family and chose N2 series (cascade lake 2.7 ghz). As machine type select custom witch enables you to chose vCPU(thread) count and memory size. LLR tasks require very little memory, so a 2 thread 1 gig VM will be quite productive.
Several 2 thread VM's will be less likely to suffer a shutdown in preemptive mode than say one 16 thread instance.

Creating preemptive VM click Management, security, disks, networking, sole tenancy and chose the management tab and scroll down to Preemptibility and select on
This will reduce price to about a third and your VM will shut down after max 24 hours depending on the load on the datacenter you have chosen. Keep in mind that preemptive instances can be shut down any time and sometimes even after 15 minutes (!) The key is to create a bunch of small VM's spread across different datacenters, and keep an eye on them a couple times a day to restart those that where shut down. Download Cloud Console on your phone if you away for a couple of days. Also be aware that price differs across datacenters.

It's very common to get your account frozen for atypical activity if you run more than 6 droplets. Happened to a good number of us. For one of my accounts I was told it would not be reopened. For another I can now max out my droplets without issue.

It seems they answer issues about this in various ways. Hopefully yours, Soulfly, will be answered in a positive good way. Often they let you continue.

And yes, being billed for a locked account happened to me too in the past on one account. That account was permanently locked and I was never billed for the charges that accrued however I watched them build up.

Their customer service is lacking for the common user. We've all seen it.

Now however, Rytis has a business thing going with DO for TSC (The Science Cloud) and apparently once you reach a spending limit of $500/month+ your support level increases.

Soulfly, I just noticed it now. That Google Cloud post was informative. I did not know about the preemptive shutdowns to reduce cost or about the N2 2t/1GB instances.

Digitalocean has a good guide about PuTTY and SSH keys: https://www.digitalocean.com/docs/droplets/how-to/connect-with-ssh/putty/

Let me know if that helps. If it's too tailored to Digitalocean and you are having trouble using this guide with GCP, let me know and I can try walk you through.

It should be pretty simple.
