Is there the possibility to get the defaults/default option for the ICS components (compiler, impi...)

Is there the possibility to get the defaults/default option for the ICS components (compiler, impi...)

Hi,

I would like to know the "defaults" of the Intel Cluster Studio. Ok it is clear that I could check all the options in the reference guide for MPI for example. But is there a command line or a file where I could check that ?

For the intel Compiler I found the "-dryrun" option. For example:
ifort -dryrun myprog.f90
I find that very usefull to know what we are exactly doing.

But for Intel MPI I don't find a similar method. For example I know that I_MPI_PIN is set to 1 per default. How can I check all the I_MPI* options ?

Thx
Regards,
Guillaume

Hi Guillaume,

I'm afraid it's impossible! :-)
There are about 100 environment variables and some of them depends on the memory, fabrics, number of processes, cache size and so on.
But if you are talking about collective operations you can get this information setting I_MPI_DEBUG=6

too bad!
thx for your answer.
