I use the pnet tcp/udp toolbox) along with psychtoolbox to communicate between two instances of matlab in different machines. One of my machines is a 32 bit win7 running matlab 2010b. The other is a 64 bit win 7 running matlab 2012a. I have a problem in transferring data from one computer to the other.
我使用pnet tcp/udp工具箱)和psychtoolbox一起在不同机器上的两个matlab实例之间进行通信。我的一台机器是一台32位的win7运行的matlab 2010b。另一个是64位的win 7运行matlab 2012a。我在把数据从一台计算机传输到另一台计算机上有问题。
Experiment 1: Run the udp_send_demo from the 64 bit computer while running the udp_plotter_demo from the 32 bit computer. Expected result: 32 bit computer plots data, waits for keyboard input. If Kb input, close figure and end demo. 64 bit finishes sending and stops demo. Actual result: 64 bit behaves as it should. 32 bit computer plots but hangs and refuses to close the demo. It does not respond to any keyboard input and has to be force closed.
实验1:在运行32位计算机的udp_plotter_demo时，从64位计算机运行udp_send_demo。预期结果:32位计算机绘图数据，等待键盘输入。如果是Kb输入，关闭图形和结束演示。64位完成发送和停止演示。实际结果:64位的行为是应该的。32位计算机绘图，但挂起并拒绝关闭演示。它不响应任何键盘输入，必须强制关闭。
Experiment 2: Run above experiment in reverse with 32 bit sending and 64 bit reading. Expected result: 64 bit plots and waits for Keyboard input. If kb input found, stop demo. Actual result the 64 bit matlab crashes claiming a segmentation violation in the mex file. It displays a stack trace (I am appending a part of it at the end).
实验2:用32位发送和64位读取反向运行上述实验。预期结果:64位图，等待键盘输入。如果发现了kb的输入，停止演示。实际的结果是64位的matlab崩溃，声称在mex文件中有一个分割的违反。它显示一个堆栈跟踪(我将在最后添加一部分)。
Playing around with the port numbers makes no difference. Recompiling the 'pnet.c' source file instead of using the precompiled mex makes no difference. Question: Has anybody tried something like this? Did you get it to work? Can you suggest things to try to get this to work without having to install 32 bit matlab in my Win64 computer?
使用端口号进行操作并没有什么区别。重新编译的pnet。c'源文件而不是使用预编译的mex是没有区别的。有人试过这种方法吗?你工作了吗?你能建议在我的Win64计算机中不安装32位的matlab程序来实现这个工作吗?

I wrote the helpful folks at psychtoolbox. Apparently the bug was caught and resolved in the 'beta' version of psychtoolbox. If you have the latest and greatest psychtoolbox, run UpdatePsychtoolbox for a good night's sleep. See here
