Sketchlib v1.7.1

Bug fix:

• Fix stall on GPUs when regression terminates early due to no matches #60

Sketchlib 1.7.0

This updates __shared__ memory copies to use memcpy_async, a CUDA 11 feature (#59).
This also fixes a bug sometimes seen with incorrect distances being calculated on a GPU.

Sketchlib v1.6.5

Bug fixes:

• When using random matches, now checks all references are in the object, and adds them if not (previously gave a key error) #56
• The python join interface warns to regenerate random matches if present. The above error would be triggered by a join where random was copied over.
• Error in strides of the longToSquareMulti function with query-ref matrices #57

Sketchlib v1.6.4

Bug fix:

• Open HDF5 files as read only where possible (when querying). This prevents creating a lock, and allows multiple processes to access the same HDF5 file (#52)

Sketchlib v1.6.3

New features:

• Version and sketch version are saved as module attributes, makes testing module version more reliable #50
• Boundary code has been removed, now in PopPUNK package extension #50, bacpop/PopPUNK#146

Sketchlib v1.6.2

New features:

• Adds functions to grow network in 1D or 2D, by iterating boundary forward #48

Bug fixes:

• Compile without openMP

Sketchlib v1.6.1

New features:

• More optimised compile options for emcc, including removing exception handling 60a803f

Bug fixes:

• Segfault when GPU distances were calculated using multiple blocks #44

Cosmetic code changes:

• Combine matrix index functions for CPU and GPU code #44
• Reflow all of the code, fix inconsistent tab/space indentation #45

Sketchlib v1.6.0

New features:

• Add WebAssembly version (for single queries) #40.
• Allow random on/off in jaccard dist bindings #41.

Bug fixes:

• Fixed a stall with GPU distances sometimes triggered due to a misplaced __syncwarp() call.
• Check for sketches which exceed GPU shared memory size, and use global memory rather than failing if it won't fit #43.
• Check all CUDA API calls, including kernel launches.
• Remove -march=native from the CMakeLists.txt, which may have been causing Illegal Instruction errors

Sketchlib v1.5.3

• Fixes bug with ref v query distances (variable overwritten)
• Adds a test for ref v query distances

Sketchlib v1.5.2

• Modifies the operation of the sparsification of distances to correctly deal with zero distances
• Removes parallelisation of distance sparsification (causing issues on some platforms)
• SIMD openmp commands removed from matrix operations
