Abstract: In various embodiments, a proxy application receives a first storage request from a proxy driver executing on a host node. The first storage request indicates a location within the shared storage system and a first address range associated with the host node. The proxy application converts the first storage request to a second storage request that indicates the location and a second address range associated with a proxy node. The proxy application transmits the second storage request to a storage driver that executes on the proxy node and is associated with the shared storage system. The storage driver invokes a remote direct memory access data transfer operation between the shared storage system and the host node to fulfill the first storage request.

Abstract: Systems and methods are presented that reduce the downtime of communication when updating backend software of an accelerated emulation system. In at least one embodiment, by first transferring the context of the running software to the updated software and rebuilding the context map for the communication and programming the context in the accelerated emulated device, downtime can be reduced by only enabling the new software and disabling the original software after the context map has been rebuilt as the last stage of execution.

Abstract: A system includes a hardware circuitry having a device coupled with one or more external memory devices. The device is to detect an input/output (I/O) request associated with an external memory device of the one or more external memory devices. The device is to record a first timestamp in response to detecting the I/O request transmitted to the external memory device. The device is further to detect an indication from the external memory device of a completion of the I/O request associated with the external memory device and record a second timestamp in response to detecting the indication. The device is also to determine a latency associated with the I/O request based on the first timestamp and the second timestamp.
