THE GPU REAL PERFORMANCE ESTIMATION FOR MATRICES MULTIPLICATION PROBLEM
USING CUDA
Description of software approaches for matrices multiplication problem using GPUs with CUDA support are
given. Showed that "native" approach without global memory working optimization is characterized by low performance,
while approaches with using block multiplication with inner loop unrolling, shared memory using, CUDA kernels
with maximal threads number and coalesced global memory access allow more efficient using of GPU memory
that provide real performance at 100–300 GFLOP/s for modern mainstream NVidia GPUs.
Key words: matrices multiplication, algorithmic optimization, CUDA.

INFORMATIVE PARAMETERS OF ARTERIAL BLOODFLOW SPEED OF KIDNEYS
FOR DIAGNOSTIC SYSTEMS IN HESTACIONIC PYELONEPHRITIS
In the paper you will find examples of changes of the bloodflow profile in the kidney artery due to the damage
of vessels in case of pyelonephritis in pregnant women. To get the diagnostics parameters of the form of the bloodflow
profile impulse we propose to use coefficients of signal distribution into the cosine row. We have found significant
difference of these coefficients in healthy pregnant women and those suffering from serous pyelonephritis.
Key words: arterial bloodflow, informative parameters, coefficients of signal distribution, cosine row, models of
bloodflow speed.
