,nettest?By comparing the code of Nettest and Ros, it was found that there were two more socket option settings in the ROS code: SO_SNDBUF,SO_RCVBUF, both of which were set to 256*1024. Comment out the two settings options and test again.Bandwidth send-side CPU utilization at the receiving end CPU usageROS 4.42gb/s, 80% 100%Ros_directrecv 6.7gb/s 83% 100%Ros_dire

When the computer is in use, suddenly appear black screen and restart the situation, reboot, the computer or black screen. What the hell is going on here? Because the CPU pins are gold plated, and the CPU sockets on the motherboard also need gold-plated, can be used well. Because the gold has a good conductivity, not easy to oxidize, so the CPU

But the long test results are as follows: The horizontal axis of the ROS receives the number of event, in 40000 units. (x, Y) indicates that when Ros receives the x*40000 event, the bandwidth of the receiving end is Y gbits/s. Event size is 2KB. As can be seen

simulation 7-14 is shown. We can see that the multiplication, accumulation, and multiplication, and subtraction commands are correctly implemented. At the same time, we can see that the multiplication, accumulation, and multiplication, and subtraction commands require two clock cycles to be completed.
