- Hi there,
-
-
- In my previous posting on comp.parallel,I had asked for any one way to do TCP/IP on IPSC/2 .
-
- I really appreciate the responses and I found them very useful to get me starting.
-
- But I have got stuck at one point.
-
- I am able to establish the connection thru sockets to the SUN workstation.
-
- The host on the IPSC/2 sends some data on the socket to the front end on the SUN using the
- write() system call( I guess it is a library call on IPSC/2).The front end on the SUN
- does a read() to read the data.The data sent is just one integer.
-
- The point is that the front-end gets some junk value due to which I get a segmentation violation message.
-
- Is the write() system call on IPSC/2 not really reliable(I am checking for the failures in both read()
- and write() and they don't fail!).
-
- How do I send data using sockets on IPSC/2? Are there other ways or am I doing something wrong?.
