Dear developers and users I have 5 individual Linux (Ubuntu) pc with intel i7 octa core processors and 16GB RAM in each connected via a 1GBps LAN. password less ssh working properly. I have installed WIEN2K 19 in the one machine (M1 server) in the directory "/servernode1" and the case directory is "/casenode1" and through NFS I have mounted the "servernode1", and "casenode1" in other four pcs with same name local folders ("servernode1", and "casenode1") in them. I have installed ,intel compilers, libxc, fftw, elpa in all the nodes individually. I have manually edited the bash file $WIENROOT path and case directory and the WIEN2K options file. Keep all the value same in all the client nodes as it is in the server node.
alias cdw="cd /casenode1" export OMP_NUM_THREADS=4 #export LD_LIBRARY_PATH=..... export EDITOR="emacs" export SCRATCH=./ export WIENROOT=/servernode1 export W2WEB_CASE_BASEDIR=/casenode1 export STRUCTEDIT_PATH=$WIENROOT/SRC_structeditor/bin Now when I am doing parallel calculations with all the client nodes in machine file , # k-points are left, they will be distributed to the residual-machine_name. # 1:vlsi1 1:vlsi2 1:vlsi3 1:vlsi4 granularity:1 extrafine:1 # and getting the following error grep: *scf1*: No such file or directory cp: cannot stat '.in.tmp': No such file or directory FERMI - Error grep: *scf1*: No such file or directory Parallel.scf1_1: No such file or directory. bash: fixerror_lapw: command not found bash: lapw1c: command not found bash: fixerror_lapw: command not found bash: lapw1c: command not found LAPW0 END hup: Command not found. ###################Error file lapw2 error 'LAPW2' - can't open unit: 30 'LAPW2' - filename: Parallel.energy_1 ** testerror: Error in Parallel LAPW2 I have checked the with " ls -l $WIENROOT/lapw1" as suggested in the previous mailing list and got the -rwxr-xr-x 1 vlsi vlsi 2139552 Sep 26 02:41 /servernode1/lapw1 for server (vlsi is the user name in server) -rwxr-xr-x 1 vlsi1 vlsi1 2139552 Sep 26 02:41 /servernode1/lapw1 (in node1 the user name is vlsi1) -rwxr-xr-x 1 vlsi2 vlsi2 2139552 Sep 26 02:41 /servernode1/lapw1 (in node2 the user name is vlsi2) please help thanking you Indranil
