Re: [OMPI users] Passing LD_LIBRARY_PATH to orted

Hi Craig, George, list Here is a quick and dirty solution I used before for a similar problem. Link the Intel libraries statically, using the "-static-intel" flag. Other shared libraries continue to be dynamically linked. For instance: mipf90 -static-intel my_mpi_program.f90 What is not clear

Re: [OMPI users] Passing LD_LIBRARY_PATH to orted

Craig, This is a problem with the Intel libraries and not the Open MPI ones. You have to somehow make these libraries available on the compute nodes. What I usually do (but it's not the best way to solve this problem) is to copy these libraries somewhere on my home area and to add the dir

[OMPI users] Passing LD_LIBRARY_PATH to orted

I am having problems launching openmpi jobs on my system. I support multiple versions of MPI and compilers using GNU Modules. For the default compiler, everything is fine. For non-default, I am having problems. I built Openmpi-1.2.6 (and 1.2.7) with the following configure options: # module

Leonardo, These nodes are all using intel e1000 chips. As the nodes are AMD K7-based, these are the older chips, not the new ones with all the eeprom issues with the newer kernel. The kernel in use is from the 2.6.22 family, and the e1000 driver is the one shipped with the kernel. I am running

If using the Intel v10.1.x compilers to build a 64-bit version, by default (default installation), Intel invokes the 64-bit compiler. But yes, you can use the "-m64" flag as well. Warner Yuen Scientific Computing Consulting Engineer Apple Computer email: wy...@apple.com Tel: 408.718.2859
