Global memory management in a client-server DBMS architectures.
All are known to be equivalent in power up to constant factors in running time, and polynomial factors in number of processors and
global memory size, although the models are separated if processors and memory are more tightly constrained.)
If it is the last PCM, data are written back to the
global memory.
We observe that the accesses to two arrays data and indices in
global memory are fully coalesced.
(1) Init CUDA environment (2) Allocate GPU
global memory A, U, F, r, b....
To decrease the
global memory reading latency, we use a shared memory array, SMData, and adopt the three-level summation method.
The buffer between modules is realized by the
global memory on GPUs; the transmitter or receiver only allows two data transmissions between the host computer and the GPUs.
Thus, we have efficiently used the memory bandwidth reducing the number of reordering operations in the
global memory, allocating more than one bit for each crossing of the sequence, maximizing the reordering coherence, using the GPU's shared memory in order to locally sort data.
The second approach, called Shared NZ, takes advantage of shared memory to store the element data and reduce the number of transactions with
global memory. A thread block is responsible for assembling a set of nonzero entries of the system of equations.
(Tokyo SE: 6665), both
global memory suppliers, today announced that they have signed final contracts for a strategic technology partnership on joint development of memory chips (DRAMs).
