V 2.0

Version 2.0 is an almost complete rewrite of the qrmumps package. Here are some of the main changes wrt previous versions

  • Parallelism is now achieved using the StarPU runtime engine.
  • 2D block partitioning can be used for frontal matrices in combination with communication avoiding dense factorization algorithms
  • it is possible to bound the memory consumption of the parallel factorization phase
  • pipelining of operation can be achieved through the asynchronous API
  • the error handling has been deeply modified to make it thread-safe

V 1.2

  • Added a method to extract the R factor once the factorization is computed.

V 1.1

  • There is no limit to the number of concurrent instances of qrmspmatc in the C interface
  • A number of minor bugfixes
