Member Data Documentation

accesses

std::vector<Access> accesses

Records the indexes of commands that access the matrix, and the type (read, read/write, write).

It will be sorted on command index with only one record per command. Note: a write to only a part of the matrix (i.e. a submatrix that isn't the whole thing) will be recorded as an access of type read/write. Input commands are considered writes, but allocation and swap commands (which do not set up any values) are not.

allocate_command

int32 allocate_command

Index of the command that allocates the matrix (which will be of type kAllocMatrix or kSwapMatrix), or -1 if the command doesn't exist (e.g.

it is an input).

deallocate_command

int32 deallocate_command

Index of the command that deallocates the matrix (which will be of type kDeallocMatrix or kSwapMatrix), or -1 if never gets deallocated (e.g.

it is an output).

is_input

bool is_input

true if this matrix is an input to the computation (i.e.

either an input-value or an output-deriv).

is_output

bool is_output

true if this matrix is an output of the computation (i.e.

either an output-value or an input-deriv).
