Member Function Documentation

diffLapackMatrices()

template<typename scalar_t >

template void slate::Debug::diffLapackMatrices ( int64_t  m, int64_t  n, scalar_t const *  A, int64_t  lda, scalar_t const *  B, int64_t  ldb, int64_t  mb, int64_t  nb  )

static

Prints a summary of differences between matrices A and B.

Uses "." for small relative error, "#" for large relative error in an entry. For each tile, checks only the four corner 2x2 blocks, marked by letters:

[ a e - - i m ]  output as:  -----------
[ b f - - j n ]              | a e i m |
[ - - - - - - ]              | b f j n |
[ - - - - - - ]              | c g k o |
[ c g - - k o ]              | d h l p |
[ d h - - l p ]              -----------

printTiles_()

template<typename scalar_t >

template void slate::Debug::printTiles_ ( BaseMatrix< scalar_t > const &  A, const char *  name, int  fields, const char *  func, const char *  file, int  line  )

static

Prints map of all tiles with requested fields.

The printTiles macro adds the matrix name, function, file, and line. Example usage:

Debug::printTiles( A, Field_Kind | Field_MOSI )

For each tile (i, j), prints instances, first Host, then device 0, 1, etc. Each instance is a collection of letters as described below.

For all fields:

• '.' if tile doesn't exist

For Field_Kind:

• 'u' if user-owned origin
• 'o' if slate-owned origin (local non-workspace)
• 'w' if slate-owned workspace

For Field_MOSI:

• 'm' if modified, 'M' if also on hold
• 's' if shared, 'S' if also on hold
• 'i' if invalid, 'I' if also on hold

For Field_Layout:

• 'c' if ColMajor
• 'r' if RowMajor

For Field_Buffer:

• 'b' if regular buffer
• 'e' if extended
