Dear SGE users,

I have a small cluster consisting of 4 dual cpu nodes (3 x 64-bit + 1 x 32-bit).

The output of qhost is as follows:

HOSTNAME             ARCH       NPROC  LOAD   MEMTOT   MEMUSE   SWAPTO   SWAPUS
-------------------------------------------------------------------------------
global               -              -     -        -        -        -        -
32-bit-compute-0-0   glinux         2  0.00     2.4G   112.4M     1.9G    36.0K
compute-0-0          lx24-amd64     2  1.21     5.7G   346.0M   996.2M    12.5M
compute-0-1          lx24-amd64     2  1.17     5.7G   540.4M   996.2M     7.3M
compute-0-2          lx24-amd64     2  1.16     5.7G   498.8M   996.2M      0.0


I wish to submit a 2CPU job to ONE of the lx24-amd64 nodes with a request of 5G of memory, however, if I try and do this I get the following message

Jobs cannot run because resources requested are not available for parallel job
        819 

if I try and reduce the memory request to 2G it will run ok, or if it gets submitted over multiple nodes it also runs ok (but slower).  There is no memory limit on the queue, does anyone have any ideas???
