Dev branch # of CPU detection error when using CPU binding #808
Description
Test platform
ubuntu 16.10
gcc/g++ 6.2.0
numactl 2.0.11
jemalloc commit id: 5c56603
Background
We're trying to run benchmark for ceph, a distributed objectstore, and hit some issues with jemalloc if using "numactl" to bind prcocess to specified numa node. After deep analysis, we suspected it was jemalloc problem. So we tried jemalloc "run_test.sh" with prefix "numactl --membind=0 --cpunodebind=0", it ran into error on ubuntu 16.10. We also tried ubuntu 14.04, there was no error.
