Subject: Re: [OMPI users] Compiling ompi for use on another machine

Both machines are x86_64, although one is a single quad core and the other is a dual quad core, the RH installs are the same. ompi and the other program were both statically linked. After the compiles I copied the target dirs to the new machine and hoped they would run, the program I wish to run passes all its self tests except the parallel ones. One thing is that there is a previous install of opmi on the machine, ideally I woulkd like to keep that installed as it runs with other stuff. The reason I am doing this is because I have the optimized compiler installed on only one machine. I will try np -1.

> Are the two machines identical in architecture and RH installation? Is there any reason why you cannot compile on the other machine too? (Sometimes the location of dynamic libraries, etc. changes so I try to make a note to always recompile on each machine.) Are you having problems running your program on each node individually first? If not, you might try that first (i.e., with "--np 1").
