pvm question

[Centro Calculo]

Dear users

I am using scilab 4.1.2 in a rocks cluster. I am using the pvm library with the problem that pvm_spawn don't works

--> pvm_spawn("/home/sysadm1/pvmPruebas/pruebas/example_pvm.sce",1,"nw")
 ans  =
 
  - 7.  

-->pvm_error(-7)                                                       
 ans  =
 
 No such executable 

No matter what I tried, that instruction don't works.

Anybody knows what could be happening

Regards
