[Smeagol-discuss] parallel compilation problem

[ambavale sagar]

Dear All and Alex,I compiled parallel smeagol on Xeon dual processor quad core workstation with lam-mpi and intel-mkl. the program compiled without giving any error message. Now when I tried to run the /examples/gamma/leads/Au.fdf on 2 or 4 nodes using command mpirun -np 4 ~/para-smgl/smeagol.1.0b/Src/smglpara <Au.fdf>Au.out it gives me the "forrtl: severe (174): SIGSEGV, segmentation fault occurred" error and stops at particular point :
SIESTA 1.3.7  -- [1.3f1 release] (04 Feb 2004)
Architecture  : intel-parallel-sagar
Compiler flags:  
PARALLEL version
NetCDF-capable

* Running on    4 nodes in parallel

**********************
But when i use single node in a command i.e. mpirun -np 1 ~/para-smgl/smeagol.1.0b/Src/smglpara <Au.fdf>Au.outit runs successfully and ends normally. Where might be a mistake in compilation?Below is my arch.make file:****************
