SpMXSpV() [1/6]

template<typename SR , typename IT , typename IVT , class OVT >

void combblas::SpImpl< SR, IT, bool, IVT, OVT >::SpMXSpV ( const Dcsc< IT, bool > &  Adcsc, int32_t  mA, const int32_t *  indx, const IVT *  numx, int32_t  veclen, int32_t *  indy, OVT *  numy, int *  cnts, int *  dspls, int  p_c  )

static

Parameters

[in,out]	indy,numy,cnts	{preallocated arrays to be filled}
[in]	dspls	{displacements to preallocated indy,numy buffers} This version determines the receiving column neighbor and adjust the indices to the receiver's local index If IVT and OVT are different, then OVT should allow implicit conversion from IVT

One of the two versions of SpMXSpV with on boolean matrix [uses only Semiring::add()] This version is likely to be more memory efficient than the other one (the one that uses preallocated memory buffers) Because here we don't use a dense accumulation vector but a heap. It will probably be slower though.

We can safely use a SPA here because Adcsc is short (::RowSplit() has already been called on it)
