AVX Support in your VPS/Server

[girish]

Mongodb 5.0 requires AVX support. See https://github.com/docker-library/mongo/issues/485 .

Are you affected? Let us know your VPS provider and if cat /proc/cpuinfo | grep -i avx produces output. If that command does not produce any output, you are affected.

Also, found this - https://pavel.network/please-do-not-require-avx-for-your-software/

Edit: @humptydumpty has created a helpful list of CPUs with AVX support.

I have tested on Digital Ocean, Linode, Vultr, Hetzner (Dedi) . They all support AVX. But feel free to double check your server/region as well.

My Netcup server doesn't have AVX.

@girish said in AVX Support in your VPS/Server:

Neither do mine.

My Hetzner Cloud VPS servers do though.

As per that article, it's a bit shitty of people to require this.

But this seems to me to be another reason for me to consolidate my various small VPS servers on Netcup/ Hetzner into one dedicated Hetzner Server.

I also have a physical server without AVX (Zima Board). It has an Intel Celeron N3450 CPU.

@_pressanykey so that has avx2 then.

Going by the output of the "cat | grep" command, Cloud VPS from SSDnodes has AVX support.

[privsec]

What does this impact?

I havent noticed any issues

[girish]

@privsec Not currently but this will be a problem when we upgrade the mongodb addon to use Mongo 5.x and beyond. Currently, it is on Mongo 4.4 which is reaching end of life sometime next year.

So, unfortunately, we have no choice but to stop supporting servers which have no AVX when we upgrade Mongo.

@girish said in AVX Support in your VPS/Server:

VPS 8000 G9 12M iv No AVX support

[random_eric]

@girish said in AVX Support in your VPS/Server:

cat /proc/cpuinfo | grep -i avx

I have avx on my system.
AVX was launched ~2011 (https://en.wikipedia.org/wiki/Advanced_Vector_Extensions)

If a new system doesn't support avx, it's likely a celeron system or a lower speced system.

[privsec]

Do all Hetzner servers have AVX support?

Id love just one more reason to switch

[robi]

PSA:
Please note that AVX support is only a feature of the CPU generation, not any company or package bundle.

Virtualization platforms may choose to enable/disable CPU features, so there's that too.
