Remote direct memory access based implementation of the logical execution time paradigm

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• copying data from a first memory buffer of a first device to a second memory buffer of the first device, the data written to the first memory buffer during a first task;
• receiving a periodic work request;
• reading the data from the second memory buffer;
• transmitting the data to a second device in communication with the first device;
• writing the transmitted data into a third memory buffer of the second device, the transmitted data needed to complete a second task;
• and
• before a logical execution time (LET) of the second task begins, copying the data from the third memory buffer of the second device to a fourth memory buffer of the second device.
