linux下并行编程调试遇到问题

xterm报错如下：

Attaching to process 9636

Could not attach to process.  If your uid matches the uid of the target

process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try

again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf

ptrace: Operation not permitted.

解决方案：

打开文件： /etc/sysctl.d/10-ptrace.conf

修改：kernel.yama.ptrace_scope = 1 改为0

接着：sudo service procps restart

完成！
