-====== MPI ====== 
- 
-We recommend you to always use the latest versions available! 
- 
-The following MPI implementations are currently available on Mogon: 
- 
-  * [[software:​openmpi|OpenMPI]] 
-  * [[software:​intelmpi|Intel MPI]] 
-  * [[software:​mvapich2#​mvapich2_20|MVAPICH2]] 
- 
-The corresponding [[setting_up_environment_modules|modulefiles]] are all in the ''​mpi/''​ namespace. 
- 
-====== Documentation ====== 
- 
-Most MPI modules carry library specific MPI documentation as a "​manpage",​ e.g.: 
- 
-<code bash> 
-$ module load mpi/<​your MPI flavor> ​ 
-$ man MPI_Abort 
-</​code>​ 
-

- 
-====== Benchmarks ====== 
- 
-If your software allows for linking different mpi-versions,​ you can choose the optimal version according to your configuration of either package size or number of threads.

-==== Mogon I ====

-=== nodeshort === 
- 
- 
-The average latency in microsecs was measured for common MPI operations. Standard deviation of these measurements were also calculated. Package sizes increase from 2 bytes to 4096 bytes. The maximum number of threads was exhausted for each node.
