Sockets are intended for remote communication.</P><P>You can use direct shared memory communication - one processors writes data to memory, and another reads it. That simple.</P><P>For waiting/signaling you can use instructions like MWAIT or IPIs (inter-processor interrupts).</P><P><I></I></P><P></P> Wed, 18 Aug 2010 10:24:23 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Inter-processor-communication/m-p/836566#M1612 Dmitry_Vyukov 2010-08-18T10:24:23Z
