similar to: Restriciting memory usage for samba using Cgroups

Dear R ExpeRts, I'm having memory difficulties using mahalanobis distance to trying to cluster in R. I was wondering if anyone has done it with a matrix of 6525x17 (or something similar to that size). I have a matrix of 6525 genes and 17 samples. I have my R memory increased to the max and am still getting "cannot allocate vector of size" errors. My matrix "x" is

Hello, I have a server running samba version 4.7.1 on centos 7.5 1) A series of operations by a windows 10 (up to date) pc client consisting of  searching (or browsing)/opening/modifying/closing a (each time different) file multiple times on a samba share containing many files (more than 11000) goes fast for a while. 2) Then the same operation (or just the searching or opening) of the same user

Hi, I'm trying to use cgroups to limit the apache webserver but this doesn't seem to work as far as I can tell. I modified cgconfig.conf like this: group webserver { cpu { cpu.shares="250"; } } and addes this to cgrules.conf: *:httpd * webserver Looking into the "webserver" cgroup shows that the pid's of

I have 2 VMs launched by : 'virsh create <xml file>' . Both VMs get 2 vcpus (out of total 2 cores of the host) I then try bias their cpu cycle quota by manipulating the cpu_shares ( virsh schedinfo --set cpu_shares=<value> vm1/2 ) so that VM1 will get 3 times the cpu cycles VM2 gets. (e.g : VM1 cpu_shares = 150 . VM2 cpu_shares = 50) . There are no other VMs defined or

Hello All, We were under the assumption that Cgroups memory controller, limits memory based on just the RSS size of the process. However, i see that the process is getting killed even when the RSS size is very low compared to the limit in bytes. For example: cat memory.stat cache 85880266752 rss 2441216 rss_huge 0 mapped_file 8192 swap 0 pgpgin 29265847812 pgpgout 29244880354 pgfault

I had a go at writing a patch, but I think it's possible already without any patch. After launch you can get the PID of the qemu subprocess: guestfs_get_pid (g); --> returns PID You can use Linux to map this to a list of thread IDs: ls /proc/$PID/task/ --> returns a list of thread IDs [Yes, this is potentially racy, but in reality qemu has already started up fully after

Hello libvirt users, I'm using the cgroup with QEMU guests. At /etc/libvirt/qemu.conf, I have the following parameter: cgroup_controllers = [ "cpu" ] This controller is successfully mounted and libvirt is able to create subgroups for each VM, it's really great the cgroups support in libvirt. The problem is that I can only set the parameters of a given cgroup under the cpu
