arm64 failure to run any benchmark

[osingla]

Can these benchmarks run on arm64 system?
Using fedora35 on arm64
5.16.12-200.fc35.aarch64
I always get this kind of error:

Hello @osingla . In general probably they are not processor architecture agnostic, I assume it depends on a particular implementation (e.g. PHP benchmark shamelessly downloads binaries for amd64). Others may be more restrictive.

That being said, the ghz (tool we use to generate traffic) images aren't available for ARM, nor the images generated from the original repository.

It's a very good point though, it would be great to see what are the differences across CPU architectures.

@LesnyRumcajs, I was trying to run the benchmarks for arm64 architecture but I am getting the following error:

Benchmarking now...

In the script bench.sh looks line the error is thrown from the following code snippet:

# Start the gRPC Server container
        docker run \
                --name "${NAME}" \
                --rm \
                --cpus "${GRPC_SERVER_CPUS}" \
                --memory "${GRPC_SERVER_RAM}" \

As I can see the images which are getting used are not present for arm64. Could you please share your pointers on how we can build these iamges for arm64. I would be really happy to raise the PR for the same.

[fenollp]

To build images for other platforms than the local one (thus using QEMU) see: https://github.com/moby/buildkit/blob/master/docs/multi-platform.md
Then the docker image manifest should contain the multiple architectures.

[LesnyRumcajs]

This looks interesting, thanks @fenollp. It'd be interesting to see the performance hit when using QEMU (compared to native).

[fenollp]

Ah BuildKit uses QEMU only when building the image. Running containers is still outside the emulator so no performance diff there.

[LesnyRumcajs]

@fenollp That's neat, thanks. BuildKit folks don't encourage building binaries through emulation https://github.com/moby/buildkit/blob/master/docs/multi-platform.md#builds-are-very-slow-through-emulation. Fortunately, our simple gRPC servers are probably simple enough that this wouldn't matter much.

@LesnyRumcajs, I was trying to run the docker file for both architectures (arm64, x86) but I was getting the below error:

I have created this proto/helloworld/helloworld.proto file by using the mkdir command. After creating the proto directory, I was getting below error:

As I was not able to find the proto file in the repo, so I have added the proto file. Is it the right way to add the file. Could you please share your pointers if this is the correct way of adding the proto file?
Thanks in advance!

[LesnyRumcajs]

@odidev the proto file is located here. In the build script, one of those scenarios is transformed into proto/helloworld path. Please look at e.g. this benchmark which also uses Gradle.
