Dear All,
I am very new to this Forum. I have compatibility problem between Red Hat 9.0 and Fedora Core 3.
I have an installed Fedora Core -3 on our eight node cluster and MPICH-1.2.6 is used for message passing library. I purchase a code and they provide an EXECUTABLE for this purpose. They have compiled the source code using Portland FORTRAN Compiler version.4.0, gcc and MPICH-1.2.5 on Red Hat -9.0 operating system.
I tried to execute the binary code in sequential and parallel mode using MPICH-1.2.6 on our cluster which is running Fedora Core 3. The sequential code is running without any problem BUT the parallel refuse to execute on FC-3 system. When i ask to supplier, then they said that the binary might be not compatible with FC-3, because under Red Hat 9.0 environment, the code was compiled.
How to solve this problem? Is any trick so that i can execute the code on FC3?
Any help is highly appreciated.

Thank You

Sincerely Yours
Manoj

Well there isn't a whole lot your going to be able to do, but you can start by checking the library linking and make sure you have all the libs.

ldd <binary> will show you al lhe libraries the binary is dynamically linked to. Make sure they all exist and are in the correct place. If everything is there then it is most likely a verion problem, if something is just missing then you have a potentially easier job, just find and install the librarires.
