Many studies have been conducted to solve this problem. For example, lightweight kernel (LWK) and micro-kernel are different approached to reduce OS noise in HPC systems. Many supercomputers use the LWK of Compute Node Kernel (CNK) or Catamount. In the past, in applications that mainly used scientific operations and MPI implementation, the LWK showed good performance.
