Dynamic accelerator generation and deployment

An apparatus comprising:

• at least one processor;
• a memory coupled to the at least one processor;
• a field-programmable gate array (FPGA) coupled to the at least one processor that comprises an Open Coherent Accelerator Processor Interface (OpenCAPI) coupled to the at least one processor;
• a catalog residing in the memory that includes a listing of previously-generated accelerators for the FPGA;
• a computer program residing in the memory and executed by the at least one processor;
• and
• an accelerator deployment tool residing in the memory and coupled to the at least one processor, the accelerator deployment tool analyzing run-time performance of the computer program by profiling the computer program during at least one execution of the computer program to identify a code portion that will be improved from being implemented in a hardware accelerator, and:
• when the hardware accelerator is in the catalog, the accelerator deployment tool deploys a previously-generated accelerator image identified in the catalog to the programmable device to generate the hardware accelerator, and replaces the code portion in the computer program with a call to the hardware accelerator;
• and
• when the hardware accelerator is not in the catalog, the accelerator deployment tool dynamically generates from the code portion an accelerator image, deploys the accelerator image to the programmable device to generate the hardware accelerator, and replaces the code portion in the computer program with a call to the hardware accelerator.

A method for improving run-time performance of a computer program, the method comprising:

• running the computer program on a system that includes a processor and a programmable device, wherein the programmable device comprises an Open Coherent Accelerator Processor Interface (OpenCAPI) coupled to the at least one processor;
• analyzing run-time performance of the computer program;
• identifying a code portion in the computer program that will be improved by use of a hardware accelerator;
• dynamically generating from the code portion an accelerator image for the programmable device;
• deploying the accelerator image to the programmable device to generate the hardware accelerator;
• and
• replacing the code portion in the computer program with a call via the OpenCAPI to the hardware accelerator.
