Jesse Jen,
Could you try
./configure --prefix=/home/jje/mpich-install –with-device=ch4:ofi?

I am currently downloading the latest version of mpich on a ubuntu machine. I am having trouble configuring (step 1d) as I do not understand the error messages. How do i proceed? The error message I receive at the
bottom is:
This is the input:
root@master:/home/jje/mpich-3.4rc1# ./configure --prefix=/home/jje/mpich-install 2>&1 | tee c.txt
The error message I receive at the bottom is:
configure: error: no ch4 netmod selected
The default ch4 device could not detect a preferred network
library. Supported options are ofi (libfabric) and ucx:
--with-device=ch4:ofi or --with-device=ch4:ucx
Configure will use an embedded copy of libfabric or ucx if one is
not found in the user environment. An installation can be specified
by adding
--with-libfabric=<path/to/install> or --with-ucx=<path/to/install>
to the configuration.
The previous MPICH default device (ch3) is also available and
supported with option:
--with-device=ch3
Here is a imgur link with everything in between:
