Documentation: None

Internal Changes of Note from Latest fml Release:

• Changed gpumat crossprod() and tcrossprod() to use Xgemm() instead of Xsyrk() for better run-time performance.
• Switched linalg::qr_Q() and linalg::lq_Q() to use Xorgqr()/Xorglq() except in gpumat lq_Q().

Release 0.3-0 (9/6/2020)

New:

• Updated to fml v. 0.3-0:
  • Added min/max methods for cpuvec and gpuvec.
  • Added norm functions linalg_norm_1(), linalg_norm_I(), linalg_norm_F(), linalg_norm_M(), and linalg_norm_2().
  • Added condition number functions linalg_cond_1(), linalg_cond_I(), and linalg_cond_2().

API Changes: None

Bug Fixes:

• See fml 0.3-0 release.

Documentation: None

Release 0.2-1-1 (9/2/2020)

New:

• Building with MPI backend support is now optional, and disabled by default. Enable by adding --enable-mpi to the package configure args (Mac, Linux), or modifying Makevars.win appropriately. This is explained in-depth in the installation guide.
• Fixed installation issues for Windows.
• GPU backend now available for Windows.
• Added more benchmarks (inst/benchmarks/).
• Added synch() method for card objects to force a synchronization.

API Changes: None

Bug Fixes:

• Safer .NAME usage in .Call() internals.
• Added more exception guards.

Documentation:

• Clarified some things in the installation guide.
• Added Windows GPU instructions.
