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[2]: Leaving directory '/tmp/mpich-3.4.2/modules/yaksa'
make[1]: *** [Makefile:43560: all-recursive] Error 1
make[1]: Leaving directory '/tmp/mpich-3.4.2'
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,

Sam
