When running turbostat, a system with 512 cpus reaches the limit for maximum number of file descriptors that can be opened. To solve this problem, the limit is raised to 2^15, which is a large enough number. Below data is collected from AMD server systems while running turbostat: |-----------+-------------------------------| | # of cpus | # of opened fds for turbostat | |-----------+-------------------------------| | 128 | 260 | |-----------+-------------------------------| | 192 | 388 | |-----------+-------------------------------| | 512 | 1028 | |-----------+-------------------------------| So, the new max limit would be sufficient up to 2^14 cpus (but this also depends on how many counters are enabled).
