I'm doing embarrassingly parallel simulations (think Monte Carlo runs of a legacy scientific binary) and am trying to find the cheapest possible host source of x86 compute, at scale. These are jobs that are single-threaded, use maybe 2-4GB of ram, last an hour, and can be checkpointed if necessary. A c5.18xlarge on AWS has 36 physical (real) cores and on the spot market is $0.74/hr which works out to $0.02/core-hour. Does anyone know of cheaper options?

#4Both Azure and GCP have really good spot pricing in many regions (~90% off).
E.g. GCP C3 pricing is $0.003/vCPU hour and $0.004 for 1GB RAM -- where C3 = Intel Sapphire Rapids (latest gen), which should be quite a bit faster than a C5 (older Intel).
c3-highcpu-88 (44 real cores) is $0.344/hr hence
N2D (AMD Milan) has equivalents that's also in a similar price bracket
See: https://cloud.google.com/compute/vm-instance-pricing#general...
Azure has similar prices for spot with AMD CPU.
On a "smaller" cloud, Oracle cloud E4 (AMD Milan) prices are also a lot cheaper than AWS.
For an even smaller cloud there's also Hetzner cloud with dedicated cores or dedicated servers even.

This is fantastic, thank you!

#6An AX161 at Hetzner with 32 physical cores (EPYC 7502P, 64 threads) costs ~$130 per month, that works out to $0.17/hr ($0.0053 per core per hour).

#7I'm guessing ~$0.02 is probably the floor.
Even a dedicated server from OVH with similar specs is $0.02-0.04/real-not-smt-core-hour.

#8Why does one have to ask HN for this? It looks to me like the market could be more transparent here.

#9Contact joinmassive.com - much cheaper than all of this.

#10I also want cheapest compute for software video encoding, ARM or x86 is fine. can someone give suggestions? I am currently using oracle cloud
