Hi!

  Everyone!
 iIcompile NAMD/charm++ on x86_64 cluster,the network is infiniband
 the compiler is OpenMPI/mpicxx.
 
 when compiling the charmm++(charmm-6.0)., I get the message that

"charm++ built successfully.
Next, try out a sample program like tests/charm++/simplearrayhello "
 
 next ,i test the ./tests/charm++/simplearrayhello

 it pop up

#ibibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes.
# This will severely limit memory registrations.
#--------------------------------------------------------------------------
#The OpenIB BTL failed to initialize while trying to allocate some
#locked memory. This typically can indicate that the memlock limits
#are set too low. For most HPC installations, the memlock limits
#should be set to "unlimited". The failure occured here:

I type the "ulimit -l unlimited" in the command line.
 
but the problem is the same !

 what should i do next??


  thanks!
