Distribution of threads among CPUs?












0















lscpu gives:



Thread(s) per core:  2
Core(s) per socket: 32


When running an intensive 32-threads process, why does htop show almost 100% CPU activity on #1-32, but very little activity on #33-64? Why aren't the process's 32 threads distributed evenly among CPUs #1-64?
