nVIDIA GPUDirect technology is fully supported (shared memory, peer-to-peer, RDMA, async), enabling the use of CUDA-aware MPI.
Modules environment
As usual, the The software modules are collected in different profiles and organized by functional category (compilers, libraries, tools, applications,..).
The On MARCONI100 the profiles are of two types, “domain” “domain” type (chem, phys, lifesc,..) for the production activity and “programming” type (base and advanced) for for compilation, debugging and profiling activities . They and that they can be loaded together.
The "Base" profile is the default one. It is automatically loaded after login and it contains basic modules for the programming activities (xls, pgi and intel e gnu compilers, math libraries, profiling and debugging tools,..).
If you want to use a module placed under others other profiles, for example an application module, you will have to load preventively the corresponding profile:
...
For listing all profiles you have loaded you can use the following command:
...
In order to detect all profiles, categories and modules available on M100 MARCONI100 the command “modmap” is available:
>modmap
With modmap you can see if the desired module is available and which profile you have to load to use it.
>modmap -m <module name>Spack
