Encountered while allocating memory on the runs on azure. TODO: Will elaborate more.... Warning level but possible issues may arise.

Is this the full error/warning message?

FabioLuporini commented 4 years ago

is this still an issue? can we actually ignore it now?

From @George Iordanescu's on SLack: https://devitocodes.slack.com/archives/CUYR290MT/p1588879563095300

When runing the benchmark in a docker container, I get "mbind: Operation not permitted" waring. Running the container with --security-opt seccomp=unconfined fixes this, but it looks to me like using a sledgehammer to open a walnut (or whatever the English lang correspondent that is). Any guidance on this?

keithyzk commented 2 years ago

same issue here. security_opt is not working on docker swarm.The mysql log is full of information like this.

Hi Keith, it has been a long time since we last time tried this. Are you trying to run Devito on Azure? --George

Hi , George. we are not running on Azure. We have similar problems on both physical and virtual machines. Thanks Reply.

georgebisbas commented 2 years ago

Uh, I have to see this long time. Can you give as some more context? Like what machines, compilers, mpi version etc?

keithyzk commented 2 years ago

呃，我必须看到这么长时间。你能提供更多的背景吗？比如什么机器，编译器，mpi版本等？

The dockerfile is mysql official image, mysql:8.0.17 dockerfile is similar to this(It's just that the mysql version is different, I use v8.0.17) mysql official dockerfile

georgebisbas commented 2 years ago

Can you reproduce with this issue with no devito code? i.e. just an mpi ping-pong?
