Msieve 1.54:

  • Merged the CPU lanczos code from the msieve-lacuda branch, which includes long vector support; compiling with long vectors on a modern machine with a modern gcc has yielded a 10-15% speedup
  • Merged fixes by Greg Childers that enable handling singleton and clique removal for datasets larger then 16GB; after years of frustration this finally fixes the 'large dataset bug'
  • Fixed errors in MPI block Lanczos (thanks Greg Childers)
  • NFS Polynomial selection updates from many people:
    • improved estimate of final e-value
    • improved handling of the factors of leading alg. coefficient
    • reduced verbosity
    • search bounds informed by years of mersenneforum work
  • Removed exit() call from error path in NFS filtering (thanks jrcrombie)
  • Add support for more modern Visual Studio and CUDA versions (thanks Brian Gladman)
  • Made the maximum merge weight configurable (thanks Lionel Debroux)
  • Updated the makefile to build GPU code for more recent GPUs
  • Updated CUB version
  • Added a fix that avoids a crash when linking to GMP 6.2.0 (thanks bsquared)
  • Changed the default NFS filtering target density to 90
  • Converted readme file to markdown, fixed links (thanks Jupiter)
