[mpich-discuss] Building CUDA-aware MPICH fails on Ubuntu 20.04

[Raffenetti, Kenneth J.]

Hi Omlin,

This is a known issue that was fixed but unfortunately not included in MPICH 3.4.2. A workaround would be to change /bin/sh to link to /bin/bash on your system. Or you could apply this patch to /home/omlins/soft/mpich-3.4.2/modules/yaksa/src/backend/cuda/cudalt.sh:

    Dear all,
    
    Building CUDA-aware MPICH fails for me after a few seconds on Ubuntu 20.04 following the MPICH installation guide (CUDA Driver Version: 465.19.01,
    CUDA Version: 11.3).
    
    Reproducer:
    mkdir ~/soft
    cd ~/soft
    tar -xzf mpich-3.4.2.tar.gz
    mkdir /tmp/mpich-3.4.2
    cd /tmp/mpich-3.4.2
    ~/soft/mpich-3.4.2/configure --with-cuda=/usr/local/cuda --with-device=ch4:ucx 2>&1 | tee configure.log
    make 2>&1 | tee make.log
    
    
    Error:
    /home/omlins/soft/mpich-3.4.2/modules/yaksa/src/backend/cuda/cudalt.sh: 35: Bad substitution
    make[2]: *** [Makefile:8697: src/backend/cuda/pup/yaksuri_cudai_pup_hvector__Bool.lo] Error 2

    make: *** [Makefile:11141: all] Error 2
    
    
    
    The with tee created log files 'configure.log' and 'make.log', as well as 'config.log', are attached.
    
    Am I missing something or is there an issue with MPICH here?
    
    
    
    Thanks a lot in advance for helping me solving this issue!
    
    Cheers,
