AFAIK this is fully supported by the GNU build tools and to me it
looks working.
BTW: you are using PGI 10.9 as it's the last version you have access
to? They are at 11.8 by now.

It seems to be a configure behavior, but I don't unde

re you have many cores per node and even use only one `qrsh

Maybe it could be checked against MPI_ERR_LASTCODE: if it's lower or equal:
output MPI error message as observed, otherwise treat it as an application
error unrelated to MPI, forward it without error message.

If you want to limit the number of available PEs in your setup for the user,
you could request a PE by a wildcard and once a PE is selected SGE will stay in
this PE. Attaching each PE to only one queue allows this way to avoid the

[pc15370:13630] ras:gridengine: pc15370: PE_HOSTFILE increased to slots=2
And the allocation is correct. I'll continue to investigate what is different
today.

These are not honored when a job is started by SGE, instead definitions inside
SGE are used:
`man sge_config` paragraph H_MEMORYLOCKED.

Yes.
But you could also try the opposite, i.e. OMP_NUM_THREADS=1 and
MKL_NUM_THREADS=$NSLOTS
Depends of the application what's better.

at do you want to achieve in detail - just shorten the `./configure` command
line? You could also add it after Open MPI's compilation in the text file:
${prefix}/share/openmpi/mpicc-wrapper-data.txt

With "user" you mean someone compiling Open MPI?

It needs to be exported, so that child processes can use it too.

d there is the command `aprun` instead of `mpiexec` in the
jobscript on a Cray. Maybe the allocation needs to be granted first.

leave it for the time being.
what about adjusting it in /usr/share/openmpi/mpicc-wrapper-data.txt and alike?

ng on how many nodes at one time? This requirement
could be a point to start to use a queuing system, where can remove job
individually and also serialize your workflow. In fact: we use GridEngine also
local on workstations for this purpose.

info
on the command line? As MPI is a standard which is not targeting any specific
platform, most of the tutorials should apply here too, as long as they don't
access any OS specific functions.
For an Objective-C application:
$ mpicc -ObjC -framework Foundation -framework CoreLocation

be compiled by a plain gcc, but then you have to take
care of all the necessary libraries on your own.

As I don't intend to develop for 10.7 or above I stayed with 3.2.6. In the
