I am trying to run a script (astrophysics stuff) using mpirun. I executed the command:

mpirun -n 3 ./harm

and got this error:

/usr/local/bin/hydra_pmi_proxy: error while loading shared libraries: libcr.so.0: cannot open shared object file: No such file or directory
[mpiexec@sajal-Aspire-E5-574] HYD_pmcd_pmiserv_proxy_init_cb (pm/pmiserv/pmiserv_cb.c:448): assert (!closed) failed
[mpiexec@sajal-Aspire-E5-574] HYDT_dmxu_poll_wait_for_event (tools/demux/demux_poll.c:77): callback returned error status
[mpiexec@sajal-Aspire-E5-574] HYD_pmci_wait_for_completion (pm/pmiserv/pmiserv_pmci.c:196): error waiting for event
[mpiexec@sajal-Aspire-E5-574] main (ui/mpich/mpiexec.c:336): process manager error waiting for completion

Note: harm is the name of the executable script. I did some googling and found that if I install the library called: libcr-dev, the above error (regarding the problem of locating libcr.so.0) might get solve. However, when I try to install it using:

sudo apt-get install libcr-dev

I got the error:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libcr-dev

I try to find the solution to the above problem but I failed. I am using ubuntu 20.04. Could anyone help me?

The libcr package was last available on 18.04 LTS. To install it on 20.04 LTS you have to download and install it manually:

cd ~/Downloads
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/b/blcr/libcr0_0.8.5-2.3_amd64.deb
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/b/blcr/libcr-dev_0.8.5-2.3_amd64.deb

sudo apt-get install ./libcr0_0.8.5-2.3_amd64.deb ./libcr-dev_0.8.5-2.3_amd64.deb

Also I should note that hydra_pmi_proxy is provided by official mpich package. You can use it instead of locally compiled version. This will prevent problems with library and package dependencies.

Thank you so much for your help. After following your steps, I got the error that dependencies are broken. So, I fixed it using apt --fix-broken. Now, its working. Also, as I am curious about hydra_pmi_proxy, I clicked on your hyperlink but I think its broken. Could you edit it? Thanks again!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
