Dear Wangqj, The same thing happens to me. since you are using large no. of wfc, although it shows the job is running in 8 procs, but sometimes if the installation is not proper, it is running in 1 procs only.
So better you check the parallel installation using a small job, with different no. of procs and see whether its taking lesser time as no. of procs increases or not? cheers 2009/9/6 wangqj1 <wangqj1 at 126.com> > > Dear pwscf users > When I run vc-relax on the computing cluster use one node which has 8 > CPUs. > The output file is as following: > > Program PWSCF v.4.0.1 starts ... > Today is 6Sep2009 at 7:49:30 > Parallel version (MPI) > Number of processors in use: 8 > R & G space division: proc/pool = 8 > For Norm-Conserving or Ultrasoft (Vanderbilt) Pseudopotentials or PAW > ..................................................................... > Initial potential from superposition of free atoms > starting charge 435.99565, renormalised to 436.00000 > Starting wfc are 254 atomic + 8 random wfc > > After one day ,it still like this and no iteration has completed ,there is > also no error was turn up .There is no error in the input file because I > have test it on anthoer computer which has 4 CPUs and it runs well . > I can't find the reason about this ,any help will be appreciated . > Best Regards > Q.J.Wang > XiangTan University > > > > ------------------------------ > ???????????,www.yeah.net <http://www.yeah.net/?from=footer> > _______________________________________________ > Pw_forum mailing list > Pw_forum at pwscf.org > http://www.democritos.it/mailman/listinfo/pw_forum > > -- Dr. Bipul Rakshit Research Associate, S N Bose Centre for Basic Sciences, Salt Lake, Kolkata 700 098 India -------------- next part -------------- An HTML attachment was scrubbed...
