[gmx-developers] /gromacs/bin.SSE2/gmx: not found

[fernando at hypernetlabs.io]

Erik, happy to be the guinea pig! Just have to get other time-sensitive work out of the way and will look into this. I am no Gromacs/Docker expert (but I learn fast!) so it may take me a little longer than other guinea pigs in this listserv.

 

Will provide status update when there is one!

Hi Fernando,

 

I have to confess that Windows isn't a normal target for us, but at least in theory that shouldn't matter for Docker :-)

 

Background: GROMACS has some very heavy CPU-specific optimization, so normally we use separate builds for SSE2, SSE4.1, AVX, AVX2, AVX512, etc. To make this work well with Docker, but also make sure you get the fastest possible binary, the Dockerfile actually builds all of these targets and installs them in separate directories, and then we check your CPU architecture at runtime, select the right CPU target, and execute the command in that subdirectory.

 

1) Can you check (in the container) what the contents of the directory /gromacs/bin.SSE2/ is?  (and any other bin.XXX directories under /gromacs)?

 

2) As far as I know, SSE2 should be one of the default builds, simply because it's the oldest possible platform we can imagine. However, it's pretty rare for a machine to actually be that old, so maybe our detection misses something on your windows machine. Do you know what CPU model you have?  If you can execute a shell in the container, doing "lscpu" might help us diagnose it!

 

Getting things to work well in Docker under Windows would be great, so if you don't mind being a guinea-pig we'll make sure to help you get it working :-)

 

Cheers,

 

Erik

Good day all.

Using Docker Desktop and my Windows command prompt, I first successfully built the https://hub.docker.com/r/gromacs/gromacs image.

 

Successfully built d96a903309fa

Successfully tagged test5:latest

 

Then I used the following command “docker run --publish 8000:8080 --name ctest5 test5” to run a container from that image ‘test5’.

And the CLI printed the following “/gromacs/bin/gmx: 12: /gromacs/bin/gmx: /gromacs/bin.SSE2/gmx: not found”

 

Anyone has experienced the same that could provide some advice? Many thanks!

Fernando
