Easiest way to address this is to periodically suspend your calculation by
using vlib_process_suspend()
that will give chance to other process nodes to do some work.
Also, please note that all debug CLIs by default are considered thread unsafe,
which means that worker
threads are stopped during their execution and that typically happens for few
hundred microseconds.
After making your CLI handler thread safe, you can specify:
VLIB_CLI_COMMAND (foo_cli_command, static) = {
[snip]
.is_mp_safe = 1;
};
Similar applies to API handlers...
