 Manycore systems, ones which are often a large number of cores tasked with the same problem, in a shared memory environment are often throughput oriented, with the amount computation being higher amortized over a period of time, or focusing on longer running tasks/computation.

+## Threads and Processes
+Threads are fundamental units of execution, with their own program counter, and implemented in most operating system, are schedulable entities.
+
+Processes are instances of a running program. Each process has its own memory space and cannot share memory between processes.
+
+Starting threads are a bit simpler, as assigning a process needs to be registered with the OS as its own PID, as well as creation of virtual memory space by the OS.
