Hmm, the user is asking about the usage of the taskset command in Linux. Let me summarize what I've learned from the search results.

The taskset command is used for CPU affinity management - it allows binding processes or threads to specific CPU cores. This can improve performance by reducing cache misses and avoiding core contention. The key use cases are:

1. Querying current CPU affinity for a process
2. Setting affinity for an existing process
3. Launching new processes with specific affinity

The main syntax options are:

• taskset -p [mask] pid - for existing processes (using hex bitmask)
• taskset -c [list] pid - for existing processes (using comma/seperated CPU lists)
• taskset [mask] command - for launching new processes
• taskset -c [list] command - for launching with CPU list

Bitmask representation is hexadecimal - 0x1 for CPU0, 0x3 for CPU0+1 etc. The CPU lists support ranges like 0-3.
Important notes:

• Requires CAP_SYS_NICE for setting affinity (root usually)
• Part of util-linux package (install via yum if missing)
• While it binds processes to cores, other processes can still use those cores
• For true core exclusivity, need cpuset instead
• Modern schedulers already try to keep processes on same cores

The user seems to be a Linux sysadmin or developer looking to optimize performance. I'll provide a comprehensive yet practical summary covering all common use cases with examples.
