R / Rcpp使用的OpenBLAS例程仅在linux中的单个核心上运行

I am trying to run a QR decomposition (LAPACKE_dgeqrf) in R on a linux machine (CentOS) using a C++ program that is interfaced with Rcpp. Unfortunately, I see only 100% using top. This also happens on a Red Hat Enterprise Linux Server. However, the C++ program (with LAPACKE_dgeqrf) runs at nthreads * 100% when started from the terminal (independently outside of R). I compiled OpenBLAS with I am trying to run a QR decomposition (LAPACKE_
