Issue

MPI multi-node cluster jobs on Linux errors out due to SSH error.

For example, the following error may occur:

Error :/bin/ssh: $ALTAIR_HOME/altair/hwsolvers/common/python/python3.5/linux64/lib/libcrypto.so.10:
version OPENSSL_1.0.2 not found (required by /bin/ssh).

This issue can occur when the libcrypto library from Python conflicts with the library required by MPI.

Note: This issue effects OptiStruct versions 2019.0 and later.

 

Solution

Copy libcrypto from the system to the location mentioned in the error above. In the system, this library is typically in /usr/lib64.
