Hello everybody!

SKaMPI is the Karlsruher MPI benchmark. The goal of SKaMPI is to
support software developers using MPI. Therefore, the SKaMPI benchmark
and database provides performance data of many MPI operations.

I would like to announce the new release of SKaMPI (2.0). More
information and a donwloadable version can be found on the SKaMPI
homepage

http://wwwipd.ira.uka.de/~skampi

Some new features are mentioned below.

To ease reuse of SKaMPI's code, the SKaLib project (SKaMPI as a
Library) provides SKaMPI's code packaged in a library and
a detailed documentation.

As usual I appreciate any comments.

Best regards 

Ralf

Highlights of the new features are:

Time limit 
      For every suite of measurements the user can give two time
      limits: (a) the time limit for the repetition of single
      measurements, and (b) the timelimit for this suite of
      measurement.

      This eases the prediction of SKaMPI's run-time, since SKaMPI
      will only need the time given.

New Measurements 
      SKaMPI now measures all MPI's collective operations, besides
      other new measurements. So various comparisons between those are
      possible.

Node times
      SKaMPI not only measures the time until a routine has finished
      on all nodes, it also measures the times an operation takes on
      each node.
