Hi Miguel, everyone, regarding your first point: I had a similar problem on its predecessor, MareNostrum 3. The trick was to unset the global MPI variable, so in my bashrc I had something like
module load intel ... unset MPI I hope this helps! I'll also have a go at the compilation myself tonight. cheers, Helvi On 2017-10-18 18:52, Miguel Zilhão wrote: > hi all, > > i've been compiling the latest ET on marenostrum 4, and there were a > couple of issues i'd like to ask: > > 1. on marenostrum, they bundle a lot of mpi-related tools on modules. > in particular, one of the > default modules that is loaded is called 'impi'. this module sets the > global variable $MPI to 'impi', ie > > $ echo $MPI > impi > > this seems to severely interfere with the Cactus building process. at > the configuration stage i get > the following: > > Configuring with flesh MPI > Warning: use of flesh MPI via MPI option is deprecated and should > be replaced with the thorn > ExternalLibraries/MPI and its MPI_DIR option > MPI selected, but no known MPI method - what is "impi" ? > > to workaround this problem, i've unloaded the module (module unload > impi), which undefines the $MPI > variable. after this, the configuration stage works fine. > this seems to me like a bug, though. after all, a cluster-wide global > variable called $MPI seems > like a natural thing to exist in a lot of these machines... should > the building of Cactus rely on > the non-existence of such a variable? > > the other inconvenient thing is that, by unloading the impi module, > one also removes from $PATH the > mpirun command. so one has to unload the module for compiling the > code, and then load it back to be > able to run it. > > 2. i was not able to compile with any of the provided intel compilers > (with gcc it worked fine). i > know there are known issues with some versions of the intel > compilers; is there some sort of list of > intel compilers that are known to work? i could maybe try to ask the > technical support if they could > make those specific versions available... > > thanks, > Miguel > _______________________________________________ > Users mailing list > Users@einsteintoolkit.org > http://lists.einsteintoolkit.org/mailman/listinfo/users -- =========================== Dr. Helvi Witek Marie-Curie Research Fellow Dep.
