Hello, I am new on this forum.
We operate a Lustre filesystem (Lustre 2.12.16 on CentOS 7.9 servers, lustre -client-2.12.4-1.el7.x86_64.rpm and lustre -client-dkms-2.12.4-1.el7.noarch.rpm on CentOS 7.3 clients, simple installation following official documentation on wiki Lustre). When data processing is consuming about 75%-80% of CPU cores on a client : - lustre performance decrease but only on the overload client (normal performance on other clients) - system performance decrease on the overload client, with %CPU sys much higher than similar systems working on local filesystems - nothing to notice on lustre servers This happens even when attending short peaks of CPU consumption and whatever the data processing. Have you ever notice such troubles on your installations ? If yes, is there any solution to this problem ? Best regards, Karine
