Dear GROMACS users,<br><br>I'm a new user of GROMACS. The command "mpirun -np 8 mdrun" is working well in a node with 8 processors.<br><br>Now
I want to run GROMACS parallel on more processors, i.e., multiple
nodes. I tried to use "mpirun -n 16 -host node018,node022 mdrun"
(node018 and node022 each has 8 processors), it gives the following
message:<br>
"<br>mpirun was unable to launch the specified application as it could not find an executable:<br>Executable: mdrun<br>Node: node018<br>while attempting to start process rank 0.<br>"<br>I also tried to use "mpirun -hostfile hostlist mdrun" (hostlist file as follows), the same message as above appeared.<br>
"<br>node018 slots=8<br>node022 slots=8<br>"<br>While the same commands works well for other softwares. Have anyone encountered similar problem? What is your solution?<br><br><br><br>Thanks in advance!<br clear="all">
