xhpl: error while loaded shared libraries libopenblas.so.0 #1479

Closed shafayetrahat closed 6 years ago

shafayetrahat commented 6 years ago

I build hpl with openmpi and openblas (Nehalem). When I run(mpirun -np 4 xhpl) it on single node it works fine. But when I use (mpirun -np 8 -machinefile node xhpl) on 2 node it gives me : Primary job terminated normally...... xhpl: error while loaded shared libraries libopenblas.so.0 .No such file or directory. I have checked my library path. They are ok.

Perhaps it is a dependency of libopenblas.so that is missing on the other node, like gfortran's libquadmath or libgfortran itself ?

I have solved it. It's the I have to write in ldconfig configuration file(ld.so.conf/openblas.conf).
