https://community.intel.com/t5/Intel-MPI-Library/maximum-size/m-p/826820#M1241 Hi Joe,<BR /><BR />It seems to me that internal implementation of MPI functions may limit the maximum size of a structure which can be transferred at once. But I think that it should not be less than 2GB. You can write a small test case and check this limitation.<BR /><BR />Regards!<BR /> Dmitry<BR /> Wed, 12 Jan 2011 09:11:44 GMT Dmitry_K_Intel2 2011-01-12T09:11:44Z https://community.intel.com/t5/Intel-MPI-Library/maximum-size/m-p/826819#M1240 Hi,<DIV></DIV><DIV>I was wondering which is the maximum size of a data structure that can be send via MPI_Ssend or MPI_Broadcast. I suppose it's implementation dependent. If so, which factors determine it?</DIV><DIV></DIV><DIV>thanks in advance,</DIV><DIV></DIV><DIV></DIV> Mon, 10 Jan 2011 19:55:09 GMT https://community.intel.com/t5/Intel-MPI-Library/maximum-size/m-p/826819#M1240 Jose_Gordillo 2011-01-10T19:55:09Z https://community.intel.com/t5/Intel-MPI-Library/maximum-size/m-p/826820#M1241 Hi Joe,<BR /><BR />It seems to me that internal implementation of MPI functions may limit the maximum size of a structure which can be transferred at once.
