This patch fixes a runtime error when launching an MPI program using
mpiexec/mpirun in an environment where the ssh command is not
available.
* gnu/packages/mpi.scm (openmpi-4)[inputs]: Add openssh-sans-x.
(openmpi-4)[arguments]: Fix path in code.
Change-Id: I65255186c37b6eaba3c283c7046163abc2cb38b7
---
The runtime error can be reproduced with:
---8<------------------>8---
$ guix shell -C openmpi@4 hello -- mpirun -np 2 hello
--------------------------------------------------------------------------
The value of the MCA parameter "plm_rsh_agent" was set to a path
that could not be found:
plm_rsh_agent: ssh : rsh
Please either unset the parameter, or check that the path is correct
--------------------------------------------------------------------------
[guix-A102:00001] [[INVALID],INVALID] FORCE-TERMINATE AT Not found:-13 - error plm_rsh_component.c(335)
---8<------------------>8---
The size of the closure as given by guix size is 406.7 MiB after the
patch vs 398.3 MiB before the patch.
