'--disable-fortran' is a configure option. Can you try to configure with '--disable-fortran’ and rebuild MPICH?

Re: [mpich-discuss] MPI / openmp - big static arrays fortran
by William Gropp 15 Mar '15

Because the module could be used in a routine, not just the main program, Fortran probably allocates it off of the stack (the way it manages memory). If there is one thread, then it is easy to make that stack very large. If multiple threads *might* be used, it gets harder. Typically, the Fortran compiler and runtime divides the memory in to multiple stacks, one for each (potential) thread. This reduces the amount of space available to each thread’s stack, and can cause problems with data that is allocated on the stack. The two common options are (a) don’t allocate the space like this - allocate it dynamically or (b) tell the compiler that you need larger stacks for the threads.

Re: [mpich-discuss] MPI broadcast question
by William Gropp 15 Mar '15

15 Mar '15

It depends on how the broadcast is being used. In many cases, minimum completion time is the goal, and the hierarchical communication is preferred. There are cases where minimum process time is the goal *and* there is flexibility as to timing; in that case, simple linear algorithms can be better. But for the common case, the hierarchical methods are better because they have relatively low total time and time per process; if the linear algorithm doesn’t satisfy all the rules, it can be very slow. Note also that for broadcasts that involve more than a small amount of data, the algorithm is usually not a tree but a hierarchical scatter/allgather approach.

MPI / openmp - big static arrays fortran
by Jan Wittke 15 Mar '15

Hi, I have a strange problem. When I compile this code: module user implicit none type user_type real :: value integer, dimension(30,30) :: array end type end module program test_mpi use user implicit none integer, parameter :: num = 1e5 type(user_type), dimension(num) :: var var(1)%value = 19. write(*,*) var(1)%value end program with gfortran and run it there is no problem. Now If I compile this program with mpifort -fcoarray=lib -fopenmp testmod.f95 -lcaf_mpi and run it with mpirun -np 1 ./a.out I got an error Segmentation fault (signal 11) Now if if compile it with mpifort -fcoarray=lib testmod.f95 -lcaf_mpi everything is fine. Why is it a problem to add the option -fopenmp with this code? Doing some web searches suggests that using big static array will not work . Thanks Jan _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss

MPI broadcast question
by YANG Fan 15 Mar '15

15 Mar '15

Hi, I learnt that MPI does broadcast with some tree-based hierarchical communication, which result in O(log p) latency, where p is the number of processes. However, I'm thinking that if I do the broadcast naively(send to all receivers simultaneously), seems that conceptually the latency can be reduced to O(1). Does the above make sense? Thanks!

Re: [mpich-discuss] uninstall mpich

I think "make uninstall" is the correct command. I tested on my laptop, it will delete libmpich.a and libmpichcxx.a. In your case, is it because other issues that cause the uninstall command to fail, e.g. file permissions? You may need to manually remove them, then. -- Huiwei Lu Postdoc Appointee Mathematics and Computer Science Division Argonne National Laboratory On Fri, Mar 13, 2015 at 2:27 PM, Wei-keng Liao <wkliao(a)eecs.northwestern.edu > wrote: > What is the right command for uninstalling mpich? > I tried "make uninstall" but I could still see > many library files left in the installation directory, > such as libmpich.a and libmpichcxx.a etc. > (most of the command files are deleted, such mpicc etc.) > > I am using mpich-3.1.4 > > Wei-keng > > _______________________________________________ > discuss mailing list discuss(a)mpich.org > To manage subscription options or unsubscribe: > https://lists.mpich.org/mailman/listinfo/discuss > _______________________________________________ discuss mailing list discuss(a)mpich.org To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
