https://community.hpe.com/t5/operating-system-hp-ux/fortran-and-shared-memory/m-p/3018629#M718798 Hi everyone<BR /><BR />We have 2 programs - one in C and one in Fortran (F90) that access the same shared memory. The C prog creates it and the Fortran program accesses it. This works well on the HP9000 D Class HP-UX 11.00 E.<BR />We moved the binaries to our new server - rp2470 HP9000 A Class HP-UX 11.00 U.<BR /><BR />This is what happens on the new server:<BR /><BR />1. The C program successfully creates the shared memory.<BR />2. The Fortran program successfully attaches to it. But just as the Fortran program exits (the last line of the program) it releases the shared memory.<BR /><BR />This is obviously a problem because other programs need to use it.<BR /><BR />The biaries work well on the first server but the Fortran removes the shared memory on exit on the new server.<BR /><BR />Does anyone have any ideas why this is happening or what I could do to overcome it.<BR /><BR />Thanks in advance<BR />PA<BR /> Wed, 09 Jul 2003 05:07:22 GMT JUP 2003-07-09T05:07:22Z https://community.hpe.com/t5/operating-system-hp-ux/fortran-and-shared-memory/m-p/3018629#M718798 Hi everyone<BR /><BR />We have 2 programs - one in C and one in Fortran (F90) that access the same shared memory.
