TFTP (trivial file transfer protocol) broadcast controller

A computer program product (CPP) comprising:

• a set of non-transitory storage device(s);
• and
• computer code stored collectively in the set of storage device(s), with the computer code including data and instructions to cause a processor(s) set to perform at least the following operations:
• providing a computer system including:
• a trivial file transfer protocol (TFTP) server computer, a system management controller computer and a set of subnet(s) including a first subnet, with each subnet of the set of subnet(s) including a primary computer and a plurality of host computers that respectively include a field programmable gate array (FPGA) with programmable blocks,
• polling, by the system management controller, each computer of the first subnet to determine that all of the computers of the first subnet are ready to receive a broadcast of an FPGA image,
• responsive to the determination that all of the computers of the first subnet are ready to receive the broadcast of the FPGA image, instructing the TFTP server computer to send the FPGA image to all of the machines of the first subnet, and
• sending, by the TFTP server computer and to all of the computers of the first subnet, the FPGA image;
• wherein the system management controller computer uses an exclusive and direct communication path with the respective FPGAs of the plurality host computers of the set of subnet(s);
• and
• wherein the polling operation uses the exclusive and direct communication paths.
