Hi all, the cgroup cpuset and memory reduce access to a part of the resources on the system. Some applications use the /proc/cpuinfo and /proc/meminfo to allocate the resources. For instance, HPC jobs look at /proc/cpuinfo to fork the number of cpu found in this file either look at /proc/meminfo to allocate a big chunk of memory. Each process set the affinity on each cpu, which in case a subset of cpus is used, some affinity will fail. In the case of the container, the cgroup is used to reduce the memory or to assign a cpu to the container. Unfortunately, as this partitioning is not reflected in /proc, the different system tools (ps, top, free, ...) show a wrong information. I was wondering if that would make sense to create for the different cgroup subsystem, when it is relevant, a proc formatted file we can bind mount /proc. For example: /cgroup/memory.proc and /cgroup/cpuset.proc Any ideas ? -- Daniel _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
