It looks like you did not compile the parallel version of the code (which happens when ./configure cannot detect mpi libraries), or you did some mistake in the mpi configuration (is the binary present on all computers?). Does the configure script shows these lines at the end: Parallel environment detected successfully. Configured for compilation of parallel executables. > When I complied PWscf, some errors appeared when make all: > IPO Error: unresolved : mpi_conversion_fn_null_ > Referenced in ../Modules/parallel_include.o > Referenced in ../Modules/ptoolkit.o > Referenced in libiotk.a(iotk_error.o) You can disable Interprocedural Optimizations (IPO) with the option -no-ipo. IPO is usually a source of troubles; it didn't worked at all on some versions of ifort (maybe 9.0). Please give us more details, like you configure output, compiler and mpi flavour. regards -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) +39 040 3787 511 http://people.sissa.it/~paulatto/ ---------------------------------------------------------------- SISSA Webmail https://webmail.sissa.it/ Powered by SquirrelMail http://www.squirrelmail.org/
