 mpirun-debug option fails to open xterm windows. A race condition may
occur when there are multiple processes trying to lock the
$HOME/.Xauthority file concurrently. An error similar to this may occur:
/usr/X11R6/bin/xauth: error in locking authority file
/home/<user>/.Xauthority
Disable X11 forwarding by setting the environment variable
$MPI_SHELL_X='ssh -x'. Then set the DISPLAY environment variable with
the mpirun -display option. For example:
env MPI_SHELL_X='ssh -x' mpirun -debug -display\
<X11_display_hostname:display_number.screen_number> [...]

 An SRP write performance bug between QLE7240/QLE7280 and LSI
(Engenio) storage systems was fixed. To apply this fix, modify the
srp_sg_tablesize and max_sect parameters. To modify
srp_sg_tablesize, do one of the following:
 Add the following line to /etc/modprobe.conf:
options ib_srp srp_sg_tablesize=80
 Define srp_sg_tablesize when adding the ib_srp module (as root):
modprobe ib_srp srp_sg_tablesize=80
 If using srp_daemon, modify max_sect by adding the following
command to /etc/srp_daemon.conf file:
a id_ext=200500A0B81146A1,ioc_guid=00a0b80200402bef
,max_sect=2048
 To ensure proper operation of MPI, the QLogic OFED+ INSTALL sets the
memory locking limits in the /etc/security/limits.conf file to
unlimited, due to the large amounts of memory needed to run the MPIs.
Open MPI recommends using unlimited ulimits for lockable memory. For
more information, see:
http://www.open-mpi.org/faq/?category=openfabrics#ib-locked-pages
An alternative is to use the --mca mpi_leave_pinned 1 option with
mpirun.
