ubuntu mpich

Dear sir/madam Hello. I am running Ubuntu 12.0.4 LTS (my computer is dual boot with win XP SP3 and ubuntu). I can swear that I have run the example 'cpi' in the package 'mpich-3.0.4'. but now, see the result of executting soheil@soheil-desktop:~/mpich-3.0.4$ mpiexec -n 4 ./examples.cpi > [proxy:0:0@soheil-desktop] HYDU_create_process > (./utils/launch/launch.c:75): execvp error on file ./examples.cpi (No such > file or directory) > [proxy:0:0@soheil-desktop] HYDU_create_process > (./utils/launch/launch.c:75): execvp error on file ./examples.cpi (No such > file or directory) > [proxy:0:0@soheil-desktop] HYDU_create_process > (./utils/launch/launch.c:75): execvp error on file ./examples.cpi (No such > file or directory) > [proxy:0:0@soheil-desktop] HYDU_create_process > (./utils/launch/launch.c:75): execvp error on file ./examples.cpi (No such > file or directory) > > =================================================================================== > = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES > = EXIT CODE: 255 > = CLEANING UP REMAINING PROCESSES > = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES > > =================================================================================== > soheil@soheil-desktop:~/mpich-3.0.4$ Also, 'whiching' mpicc and mpiexec both return /user/local/bin/mpicc and /user/local/bin/mpiexec, respectively. I mean I have installed mpich before and sat the PATH variable. I need mpich on my ubuntu. Please help.

reading from a read only directory
by Geoffrey Irving 27 Nov '13

27 Nov '13

I got the following error trying to slurp in a large file (slice-17.pentago) with MPI_File_read_ordered: rank 0: pentago/mpi/io.cpp:read_sections:397: MPI_File_read_ordered(file,raw.data(),raw.size(),MPI_BYTE,MPI_STATUS_IGNO ADIOI_CRAY_OPEN(102): Access denied to file all-1/.slice-17.pentago.shfp.670064 The directory all-1 was read only due to paranoia over accidentally deleting expensively obtained data. Looking at ADIOI_Shfp_fname in the mpich source, it looks like this error is intentional: the shared file pointer routines generate temporary files in the same directory as the read-from file. I couldn't find any attempts at recovery if the file cannot be written in that place. This behavior doesn't seem to have changed since the beginning of the git repository. Is my reading of the code correct: MPI_File_read_ordered can't be used on a file in a read only directory? I can see the motivation for this in the case of noncollective shared routines: since the other processes aren't necessarily doing any MPI at the moment, the only way to synchronize is through the file system. And because there might be all sorts of different filesystems in operation, the easiest way to ensure that we're touching the right one is use the same directory. I can't imagine any reasonable use of the noncollective shared routines, but maybe that's a different discussion. Is this an unfortunate leak between broken routines which need questionable trickery and perfectly good routines like MPI_File_read_ordered? Thanks, Geoffrey

Maybe it would help if Hydra used TTY options to make errors like "No such file or directory" show up in red the way Clang does :-) Jeff -- Jeff Hammond jeff.science(a)gmail.com

Re: [mpich-discuss] error in make

We build with Intel compilers everyday without any problem. I am wondering if your installation of icc is ok, i.e., does it have all the header files it needs.

error in make
by Park, Soohyung 26 Nov '13

Hi, When I tried to install mpich-3.0.4, “make” failed. I have no idea why it failed because “configure” was successfully done. The “make” was killed after showing the following message: ../src/include/mpiimpl.h(105): error: identifier "useconds_t" is undefined int usleep(useconds_t usec); If I can get any help resolve this issue, it would be greatly appreciated. Attached please find the c.txt & m.txt Thank you, Soohyung Park

Re: [mpich-discuss] rank ordering from MPI_Cart_create
by Rajeev Thakur 25 Nov '13

25 Nov '13

If you use a Cartesian topology, you have to follow the ordering it uses and use MPI_Cart_shift to know who the neighbors are in each direction. If the application insists on a different ordering, you could use one of the Dist_graph topologies where you explicitly specify who the neighbors are.
