Hi everyone, I am trying to build my own system for my nodes - minimalistic. I tried to make things easy so I didn't even recompile openMPI for it, I just copied everything from my Ubuntu installation (I know, it's very dirty, but I stick to KISS :) ). Before, things just worked perfectly with the libraries. I only recompile executable binaries, not Glibc (not openMPI, I also didn't succeed compiling openMPI but that's a different story).
So, as I keep trying to run Hello world! program, I keep getting the same error message every time. Everything in the system is fine from my point of view. The error message is this: [user:24307] mca: base: components_open: component timer / linux open function failed -------------------------------------------------------------------------- It looks like opal_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during opal_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): opal_carto_base_select failed --> Returned value -13 instead of OPAL_SUCCESS -------------------------------------------------------------------------- [user:24307] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ../../../orte/runtime/orte_init.c at line 77 [user:24307] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ../../../orte/orted/orted_main.c at line 315 I tried googling and searching the archives, nothing gave me a hint. What might be missing? Should I really try to recompile openMPI? What needs to be on/off in the kernel? Any ideas? Thanks in advance, bremby
