Hi, everyone,

   I had a protein with ligands. When I put it into MD, it reported in heat step:
         Error: unspecified launch failure launching kernel kNLSkinTest
         cudaFree GpuBuffer::Deallocate failed unspecified launch failure

   I first see the 'RESTARTED DUE to LINMIN FAILURE' in min.out, So I followed the tips in the following link:
         http://structbio.vanderbilt.edu/archives/amber-archive/2008/1340.php
   I change the "imin=1,maxcyc=10000,ncyc=1000, " to " imin=1,maxcyc=22000,ncyc=12000,"úČ But the 'RESTARTED DUE to LINMIN FAILURE' happened too (as follow):
                      NSTEP ENERGY RMS GMAX NAME NUMBER
            11850 -5.5996E+05 1.7727E+04 8.3886E+06 O24 13965
         
           BOND = 30484.6520 ANGLE = 2193.6343 DIHED = 8605.7828
           VDWAALS = 43827.3652 EEL = -641883.3917 HBOND = 0.0000
           1-4 VDW = 3102.4665 1-4 EEL = -6294.4058 RESTRAINT = 0.0000

               .... RESTARTED DUE TO LINMIN FAILURE ...
         
               .... RESTARTED DUE TO LINMIN FAILURE ...
         

    I noticed that in some reply: "the RESTARTED DUE TO LINMIN FAILURE" can be ignored and I find the min.rst seems no error.
    So I continue the heat by using this min.rst. And the error as follows:
         Error: unspecified launch failure launching kernel kNLSkinTest
         cudaFree GpuBuffer::Deallocate failed unspecified launch failure

    So which is the key problems in my MD?
    1. To change the force field parameter of ligands? The force field of ligands is generated in antechamber, it seems no errors (as attachment).
    2. Change the min.in ? How to change? Anyone have ideas?
    3. change the heat.in ? How to change?

    Thanks for you reply.

                                                                                                                                                                         Chen.
