cpu_smt

Using AI Code Generation

1$cpu_smt = phodevi_cpu::cpu_smt();2echo $cpu_smt;3If you are using the phodevi_cpu class, you can also use the cpu_core_count() method to get the number of physical cores in the CPU. You can then use this value to determine the number of threads to use in a multithreaded application. For example, if you wanted to use 2 threads per core, you could use the following code:4$cpu_core_count = phodevi_cpu::cpu_core_count();5echo $cpu_core_count;6$cpu_core_count = phodevi_cpu::cpu_core_count();7$threads = $cpu_core_count * 2;8echo $threads;9$cpu_core_count = phodevi_cpu::cpu_core_count();10$threads = $cpu_core_count * 2;11echo $threads;12$cpu_core_count = phodevi_cpu::cpu_core_count();13$threads = $cpu_core_count * 2;14echo $threads;
