Tendermint on old CPUs

[smalla]

is tendermint supposed to run on old cpus like E5-4650? I havent found in any documentation if there is a limitation, but Im getting this error:
(*BlockchainReactor).poolRoutine\n\tgithub.com/tendermint/tendermint@v0.34.14/blockchain/v0/reactor.go:398\nfailed to execute message; message index: 0: Error calling the VM: Error instantiating a Wasm module: Error instantiating module: CpuFeature("EnumSet(BMI1 | BMI2 | AVX2 | LZCNT)"): execute wasm contract failed" module=state

my CPU does not have these features, and Im not sure if it is a feature or a bug.
(or it is a limitation of wasm eventually?)

Thank You.

Tendermint doesn't use WASM internally for anything. Probably a good idea to speak to whoever maintains the application you're running on top of Tendermint.

so it supposed to run on every processor and this particular errors is coming from in the wasm module ?

[thanethomson]

We make no guarantees about Tendermint running on every processor. Also, this error is not coming from Tendermint at all. Tendermint doesn't have a WASM VM inside of it. What application are you running on top of Tendermint?

It is a terrad daemon, supposed to be a validator node. I have replaced the server since last message, so cannot test it anymore.
However I have found out this only happens if there are invalid transactions to be processed. Thank You for Your time.

Transaction processing is handled by the application (in this case that's terrad). You are encountering an application problem here - not a Tendermint one.
