Reducing remote reads of memory in a hybrid computing environment by maintaining remote memory values locally
First Claim
1. A method of reducing remote reads of memory in a hybrid computing environment by maintaining remote memory values locally, the method comprising:
- writing by an accelerator when one or more memory values in accelerator application memory change, to shared memory of the host computer, one or more packets of data representing the changes in accelerator memory values, including incrementing a counter value representing the total number of packets written by the accelerator to the shared memory in the host computer; and
reading by the host computer asynchronously with respect to the writing, from the shared memory in the host computer, the packets of data written by the accelerator to the shared memory in the host computer, including moving the read data to application memory of the host computer and incrementing a counter value representing the total number of packets read by the host computer from the shared memory in the host computer.

Abstract
Reducing remote reads of memory in a hybrid computing environment by maintaining remote memory values locally, the hybrid computing environment including a host computer and a plurality of accelerators, the host computer and the accelerators each having local memory shared remotely with the other, including writing to the shared memory of the host computer packets of data representing changes in accelerator memory values, incrementing, in local memory and in remote shared memory on the host computer, a counter value representing the total number of packets written to the host computer, reading by the host computer from the shared memory in the host computer the written data packets, moving the read data to application memory, and incrementing, in both local memory and in remote shared memory on the accelerator, a counter value representing the total number of packets read by the host computer.

11. A hybrid computing environment for reducing remote reads of memory by maintaining remote memory values locally, the hybrid computing environment including computer memory and a computer processor, the computer memory including computer program instructions that, when executed by the computer processor, cause the hybrid computing environment to carry out the steps of:
-
writing by an accelerator when one or more memory values in accelerator application memory change, to shared memory of the host computer, one or more packets of data representing the changes in accelerator memory values, including incrementing a counter value representing the total number of packets written by the accelerator to the shared memory in the host computer; and reading by the host computer asynchronously with respect to the writing, from the shared memory in the host computer, the packets of data written by the accelerator to the shared memory in the host computer, including moving the read data to application memory of the host computer and incrementing a counter value representing the total number of packets read by the host computer from the shared memory in the host computer. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory computer program product for reducing remote reads of memory in a hybrid computing environment by maintaining remote memory values locally, the computer program product disposed in a recordable, computer readable medium, the computer program product comprising computer program instructions capable, when executed, of causing the hybrid computing environment to function by:
-
writing by an accelerator when one or more memory values in accelerator application memory change, to the shared memory of the host computer, one or more packets of data representing the changes in accelerator memory values, including incrementing a counter value representing the total number of packets written by the accelerator to the shared memory in the host computer; and reading by the host computer asynchronously with respect to the writing, from the shared memory in the host computer, the packets of data written by the accelerator to the shared memory in the host computer, including moving the read data to application memory of the host computer and incrementing a counter value representing the total number of packets read by the host computer from the shared memory in the host computer. - View Dependent Claims (17, 18, 19, 20)
