Hi all:


 


I am testing OpenMPI with lamtests-7.1.4 on RHEL5.2 Server SnapShot3. Since openmpi-1.2.5-2 and lam-7.1.2-11 have been shipped in RHEL images. I installed them directly. Then I downloaded lamtests-7.1.4 from http://www.lam-mpi.org/7.1/downloadphp. But I failed to run make for lamtest. Can lam-7.1.2 work together with lamtests-7.1.4?


 


Following are my steps for LAM:


1. install openmpi-1.2.5-2 and lam-7.1.2-11. mpirun and mpicc are links to openmpi interfaces.


2. create LAM user lam on all the machines. su lam
3. setup ssh to all the nodes without password
4. unzip the tarball on all the nodes
5. create bhost/boot_schema file


  xblade08.clusters.com
  xblade01.clusters.com
  xblade02.clusters.com
6. lamboot boot_schema
7. ./configure on all the nodes


8. make
 ; make[1]: Entering directory `/LTC/MPI/lamtests-7.1.4/dtyp'
  mpif77   -c -o freal16_f.o freal16_f.f
   In file freal16_f.f:67


      real*16 real16
        ;    1
  Error: Old-style type declaration REAL*16 not supported at (1)
   In file freal16_f.f:68


      real*16 real16temp
           ; 1

The message is a bit strange, but it should tell you that
your Fortran 
compiler doesn't support the real*16 extension.  You could
rebuild lam 
with a compiler which does support such an extension, such
as the compiler 
you must have used with openmpi.
By old-style, the message presumably refers to the standard
way, since 15 
years ago, of specifying data types with selected_real_kind.
 However, 
making a cosmetic change to your source won't allow it to
compile, unless 
you change your source to select the largest data type
supported by the 
compiler.
