US 12,619,463 B2 · Thread creation on local or remote compute elements by a multi-threaded, self-scheduling processor

Abstract

Representative apparatus, method, and system embodiments are disclosed for a self-scheduling processor which also provides additional functionality. Representative embodiments include a self-scheduling processor, comprising: a processor core adapted to execute a received instruction; and a core control circuit adapted to automatically schedule an instruction for execution by the processor core in response to a received work descriptor data packet. In another embodiment, the core control circuit is also adapted to schedule a fiber create instruction for execution by the processor core, to reserve a predetermined amount of memory space in a thread control memory to store return arguments, and to generate one or more work descriptor data packets to another processor or hybrid threading fabric circuit for execution of a corresponding plurality of execution threads. Event processing, data path management, system calls, memory requests, and other new instructions are also disclosed.

Dependent claims

An apparatus comprising:

a memory interface coupled to a memory;
a data cache;
an instruction cache;
and
one or more processing elements configured to:
access data from the data cache;
and
execute instructions from the instruction cache to perform operations comprising:
receiving a thread create instruction from a parent thread executing on the one or more processing elements, the thread create instruction indicating a number of return parameters to be generated by a child thread created by the thread create instruction;
reserving, via the memory interface and based on the number of return parameters, space in the memory to store the return parameters;
creating the child thread based at least in part on the reserving of the space in the memory;
and
providing access to the return parameters from the reserved space to the parent thread based at least in part on a thread return instruction from the child thread.
