I'm trying to use PALLOC memory allocator in LITMUS-RT. PALLOC uses CGROUP interface in Linux, so we need to create a CGROUP partition and assign cpus, mem nodes, and memory banks to the partition to invoke their bank-aware memory allocation. Does LITMUS-RT support Linux CGROUP? Can we run LITMUS-RT tasks within a CGROUP partition? (e.g., available cpus for global scheduler) The installation instruction page on LITMUS-RT wiki says we should disable support for group scheduling. Does it mean that we can use Linux CGROUP and only the group scheduling feature is not supported?<br class=""><br class=""></div>The paper and code links are here.<br class=""><br class=""><a href="http://www.ittc.ku.edu/%7Eheechul/papers/palloc-rtas2014.pdf" target="_blank" class="">http://www.ittc.ku.edu/~heechul/papers/palloc-rtas2014.pdf</a><br class="">
