I have make it myself.<BR /><BR />1) Today when i execute it, without debugging, i have in a console windows (it's a console project) : <B>unknown option : -localonly</B> and the program ask for a touch to stop the program. It's on visual studio 2010 on windows 7. On unix i have not this problem.<BR /><BR />I try to modify a lot of option of the compiler (i don't understand all) but <B>this errors alway arrive</B> !<BR /><BR />2) my program (when it's run) which make a product of two matrix (n,n) take a lot of time only for some dimension (n is power of 2 : 1024, 2048, 4096 ..) ! This error arrive on linux and windows.<BR /><BR />Some one has an experiment about theses errors ?<BR /><BR />Thanks you very much<BR /> Mon, 09 Apr 2012 18:18:36 GMT https://community.intel.com/t5/Intel-MPI-Library/coarray-problems/m-p/775390#M271 latomicien 2012-04-09T18:18:36Z https://community.intel.com/t5/Intel-MPI-Library/coarray-problems/m-p/775391#M272 Hi latomicien,<BR /><BR />Could you post the source code you are using, along with the compiler options you are using?
