topic one-sided communication in Intel MPI in Intel® MPI Library https://community.intel.com/t5/Intel-MPI-Library/one-sided-communication-in-Intel-MPI/m-p/801499#M821 Hi M Wang,<BR /><BR />Yes it does. Intel MPI Library does supported passive one-sided communication. Performance... I don't know.<BR />When you call MPI_Get/Put real communication will not be started until MPI_Win_Fence is called.<BR /><BR />Regards!<BR /> Dmitry<BR /> Fri, 18 Jun 2010 09:54:07 GMT Dmitry_K_Intel2 2010-06-18T09:54:07Z one-sided communication in Intel MPI https://community.intel.com/t5/Intel-MPI-Library/one-sided-communication-in-Intel-MPI/m-p/801498#M820 <BR />Does <I>Intel MPI</I> Library support <I>passive target one</I>-<I>sided communication</I>? How about the perforamnce? <BR />It seems the performance of <I>passive target </I>one-sided operations implemented through MPI-2 windows is very poor. The implementation of RMA in Intel MPI is not truly one-sided. When a process call MPI_Get/Put, the target process won't response if it is busy on its own work.<BR /> Thu, 10 Jun 2010 15:52:11 GMT https://community.intel.com/t5/Intel-MPI-Library/one-sided-communication-in-Intel-MPI/m-p/801498#M820 M_Wang 2010-06-10T15:52:11Z one-sided communication in Intel MPI https://community.intel.com/t5/Intel-MPI-Library/one-sided-communication-in-Intel-MPI/m-p/801499#M821 Hi M Wang,<BR /><BR />Yes it does.
