Hi,
I want to use the lammpi to configuration the abinit 6.8.1, can someone answer me whether it can work? And which version of the gcc should I choose?
Thanks~

It might work, but why not use the more conventional openmpi instead of lammpi? There is likely more collective experience compiling recent versions of abinit with it....

Hi,
I have configured abinit with openmpi, and I can run it with multiple CPUs during one node , however, I donot kown how to run it
by many nodes. I write a hostlist file like this :
node1:8
node2:8
node3:8
and I run the command :
mpirun -n 24 -hostfile hostlist abinit<>&log &
but it doesnot work......
can you tell me how to run it during nodes? Thanks~

Hi,

mpirun -n 24 -hostfile hostlist abinit<>&log &


perhaps, you forgot input files :(

mpirun -n 24 -hostfile hostlist abinit < files >& log &

Hi jmb,
I certainly do not forget the input file. I just did not write it out here.
mpirun -n 24 -hostfile hostlist abinit < files >& log &
I run this commend, but it doesnot work.
Thanks...

Well, you should likely find the information you need in the documentation of LAM MPI. We can only provide you with generic hints, since we are after all developers of Abinit and just users of MPI.
