   Hello!

   I would like to ask for help. I have two questions:

1) I want to run NAMD on cluster, consisting of Alpha 21264 (2 x 667 МHz)
   processors, os - TRU64 UNIX.I used Tru64-Alpha binaries from NAMD download
   page.
  
   When I use single processor everything goes fine but when I try tu run in
   charmrun mode I receive the error:
   Permission denied.
   Charmrun> Error 1 returned from rsh (localhost:0)

   So I tried in this way:

  charmrun namd2 ++local +p 2 config.namd > namd.out and I received another
  error message: execve failed to start process "namd2" with status: -1

  Does anyone know what does mean and what I have to do to solve this problem?

2) When I type charmrun it displays some options.
   I would like to know a meaning of each option - can I ask for any links?

 Thank you in advance,

 Karol
