The timeout threshold of the hpre cluster is 16ms. When the CPU and device share virtual address, page fault processing time may exceed the threshold. In the current test, there is a high probability that the cluster times out. However, the cluster is waiting for the completion of memory access, which is not an error, the device does not need to be reset. If an error occurs in the cluster, qm also reports the error. Therefore, the cluster timeout error of hpre can be masked.
