Watching some youtube videos on supercomputing is always a good way to follow the current trends.
Most of our client base uses C# for computing large scale calculation applications. But for the true heavy-duty computations there is really no alternative to C++ on Linux, including from a career perspective. So you will probably delve into g++ and possibly also clang for the extra debugging messages.
A solid understanding of how databases operate and a ready knowledge of how database performance can be increased is also required.
Finally, if you have an nVidia GPU card, there is CUDA for parallelising your application. Else - going really high end - you may have a coprocessor from Intel, such as the Xeon Phi. That in turn requires its own Intel compiler / debugger, which also readily supports parallelism.

Guides for new HPC admins

In my company, it's fallen on me to serve as the admin of our new HPC cluster, a task that's very new to me. It's very important to me to lay a solid foundation and avoid any unnecessary pitfalls. So, can anyone recommend a succinct guide or list of do's-and-don'ts for adiminstering an HPC cluster?...

hwloc_intel_mic_get_device_cpuset

Intel Xeon Phi (MIC) Specific Functions(3)		     Hardware Locality (hwloc)			Intel Xeon Phi (MIC) Specific Functions(3)

NAME

       Intel Xeon Phi (MIC) Specific Functions -

   Functions
       static inline int hwloc_intel_mic_get_device_cpuset (hwloc_topology_t topology , int idx , hwloc_cpuset_t set)
       static inline hwloc_obj_t hwloc_intel_mic_get_device_osdev_by_index (hwloc_topology_t topology, unsigned idx)

Detailed Description
Function Documentation
   static inline int hwloc_intel_mic_get_device_cpuset (hwloc_topology_t topology, int idx, hwloc_cpuset_tset) [static]
       Get the CPU set of logical processors that are physically close to MIC device whose index is idx. Return the CPU set describing the
       locality of the MIC device whose index is idx.

       Topology topology and device index idx must match the local machine. I/O devices detection is not needed in the topology.

       The function only returns the locality of the device. If more information about the device is needed, OS objects should be used instead,
       see hwloc_intel_mic_get_device_osdev_by_index().

       This function is currently only implemented in a meaningful way for Linux; other systems will simply get a full cpuset.

   static inline hwloc_obj_t hwloc_intel_mic_get_device_osdev_by_index (hwloc_topology_ttopology, unsignedidx) [static]
       Get the hwloc OS device object corresponding to the MIC device for the given index. Return the OS device object describing the MIC device
       whose index is idx. Return NULL if there is none.

       The topology topology does not necessarily have to match the current machine. For instance the topology may be an XML import of a remote
       host. I/O devices detection must be enabled in the topology.

       Note:
	   The corresponding PCI device object can be obtained by looking at the OS device parent object.
