Here is a quote I got from multiprogrammed workloads: " If you're using the O3 model, you can also assign a vector of workload objects to one CPU, in which case the CPU will run all of the workloads concurrently in SMT mode. Note that SE mode has no thread scheduling; if you need a scheduler, run in FS mode and use the fine scheduler built into the Linux kernel."
I do not need a scheduler, I just need to be able to run them on the same cpu concurrently in SMT mode. Is there a flag to start SMT mode?
