--- Comment From markp...@us.ibm.com 2014-11-11 19:13 EDT--- In the note below you state "Using last trusty ISO, I installed numactl package". Our support requires us to be at 14.04.1, I went out to the Ubuntu numactl page: https://launchpad.net/ubuntu/trusty/+package/numactl It looks like the latest trusty numactl package is numactl 2.0.9~rc5-1ubuntu2 in ppc64el which we have on our system. Can you elaborate on where the fix is available, if it is not in 14.04.1 can a patch be provided? Thanks.

--- Comment From thierry.fa...@fr.ibm.com 2014-11-18 15:49 EDT--- We have found the issue - On a bare LE system, nodes are name 0, 1 , 16 , 17 and the library search for these nodes for the meminfo file however it search for nodes 0, 1, 2 for the cpumap file. On a VM started by qemu, the nodes are named 0,1,2,3 and the problem doesn't occures. In libnuma.c, function numa_node_of_cpu() doesn't use previously created list of valid nodes but use the entire array indexed with the maximum number of nodes available on the system. Fix is to check node is valid before calling numa_node_to_cpus_v2_int() which check that the cpu belongs to that node. $ diff -urN libnuma.c libnuma.c.new --- libnuma.c 2014-11-18 10:44:32.563683894 -0500 +++ libnuma.c.new 2014-11-18 10:44:04.431683894 -0500 @@ -1403,10 +1403,12 @@ bmp = numa_bitmask_alloc(ncpus); nnodes = numa_max_node(); for (node = 0; node <= nnodes; node++){ - numa_node_to_cpus_v2_int(node, bmp); - if (numa_bitmask_isbitset(bmp, cpu)){ - ret = node; - goto end; + if (_getbit(numa_nodes_ptr,node)) { + numa_node_to_cpus_v2_int(node, bmp); + if (numa_bitmask_isbitset(bmp, cpu)){ + ret = node; + goto end; + } } } ret = -1; -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to numactl in Ubuntu. https://bugs.launchpad.net/bugs/1358835 Title: numa_node_of_cpu() returns warning when cpu_index > 79 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/numactl/+bug/1358835/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
