<pre>
This is really two separate bugs. The first is probably thorny: If another service like Dropbox is running, it can effectively block full CPU utilization. [See issue here](https://github.com/dmlc/xgboost/issues/8320#issuecomment-1272485117). Speculation in that thread is that this could be fixed with dynamic scheduling.
The second is when those processes are closed, the actual execution of OpenMP is quite unstable with these chips. Here is an error I got:
```
OMP: Error #13: Assertion failure at kmp_dispatch.cpp(1298).
OMP: Hint Please submit a bug report with this message, compile and run commands used, and machine configuration info including native compiler and operating system versions. Faster response will be obtained by including all program sources. For information on submitting this issue, please see https://bugs.llvm.org/.
zsh: abort R
