CryptMPI: A Fast Encrypted MPI Library

 As more #HPC applications move to cloud infrastructure, securing and protecting HPC sensitive data in such an environment becomes critical.

But HPC solution tends to fall short when it comes to security. Security features tend to be perceived as detrimental to the performance of the applications.

By example, encrypted communication has always been seen as incurring very significant overheads when you are aiming for microsecond latency.


The author of the Crypt MPI paper demonstrates that you can ensure the privacy and integrity of sensitive data with minimal performance degradation using an enhance MPI library.

I hope to see this kind of feature integrated as standard in a future version of MPI.

[Links of the Day] 17/10/2017: Corporate Taxes & wages, Storage with macromolecule, 25 years of MPI


  • Do Higher Corporate Taxes Reduce Wages? : interesting paper where the authors estimate that 40% of the corporate tax burden is passed onto the worker. And that most of the tax variation is directly imposed on the workforce. 
  • Macromolecules as Storage Media : the authors suggest that you can achieve a petabyte per cubic centimetre. Stability and durability are not fully addressed yet compared to another non-organic medium. However, I doubt that this can be a major concern as it can be an extremely viable solution for short-term transport of digital data. 
  • MPI symposium : MPI is 25 years old, and still improving. The venerable HPC message passing interface is still widely used and underpin a lot of non-HPC critical infrastructure such as stock markets. A must read is Jack Dongarra presentation on the evolution of MPI.

Links of the day 04 - 02 - 2015

Today's links 04/02/2015: Shared Memory API for MPI, #Openstack File Service, Dell Power FX converged hardware


  • Remote Memory Access Programming in MPI-3 : interesting proposal and method to bridge the gap between shared memory model and message passing with the de-facto standard of HPC communication library.
  • Openstack Manilla : Shared File Services for the Cloud and specifically for Openstack , interesting number : 65% of all storage sold is for file-based use cases (IDC 2012) [slides]
  • Power Fx : Dell PowerEdge FX architecture, combining Dell networking, servers, and storage into a 2U chassis. Interesting piece of technology even if the presenter is rather monotone.
