Since under some heavy computing environment(dgemm test), it takes the asic over 10+ seconds to finish the dispatched single job which will trigger the timeout. It's quite confusing although it does not seem to bring any real problems. As a quick workround, we choose to disable timeout when GPU reset is disabled.
