I have had an AWS account for a while. I have not done anything with it. Using Ubuntu with mprime in the past few months made it a bit clearer in some areas. I have been doing P-1 work for James Heinrich. This means manual reserve and submit. I do not know if this is possible in this instance. If files can be pasted and copied then this would be different.

What I am looking at now is in the attached image. It is the EC2 dashboard. I really do not know where to go from here.

Create an SSH key-pair. Spin up an instance. SSH into the instance. Profit!

I now have one running instance, one volume, one key pair, and two security groups. "SSH into the instant." I take it this would be "Connect." I gave the instance a name. Connect presents three options. I chose the third. It refused to connect so I stopped the instance.

I think I will let this go. It all looks great, but sails over this old head.

Never give up! You human; it deterministic computer. You're smarter than it is; prove it!

(I said this to someone else last year while they were making friends with Colab. They replied "Yeah, but I think it's more patient..." )

I've never been one go give up on something like this. I'll mess with it until I figure it out.

I think the EFS/EBS method in this guide is not optimal for Spot instance because you have fixed costs if you stop for a long time when spot prices are high.
  1. I have a S3 bucket, where mprime, the configuration and its savefiles are stored. The monthy costs for this will be at most 1ct, because it's a few hundered MBs only and S3 is cheap.
  2. I use the userdata script to run a bash script which copies the mprime folder from S3, then runs mprime in it and watches for the termination notice.
  3. If the 2min termination notice triggers (or some maximum runtime is done), the script will immediately stop mprime, wait 10 seconds, copy back everything to the S3 bucket and shutdown the machine.
  4. In the future, the userdata script will also immediately re-file a new spot instance request with a very low price, but for now it stops and will not continue.
  5. Assignments are done by PrimeNet, when one is finished, it will simply get a new one.
This way, my EC2 spot instances do not need any persistent EFS/EBS storage and I can set it to the shutdown behaviour to terminate. I tested that it works and plan to write a guide after I am finished with an actual candidate.

What I'm currently need help with is



  • what the settings in prime.txt and local.txt do I need for optimal performance? I don't understand which number of workers and affinity masks I will need for a c5.large instances, only found it for the older c4. Or is it still more efficient to run c4?
  • Also, do I need to run the time-consuming "Jacobi-check" on every restart of mprime? Can I disable this or should I leave it as is? Overhead is probably negligible anyway as long as the average runtime of a spot instance is at least half an hour.
