An explanation of the input/output parameters follows:
T/V : Wall time / encoded variant.
N : The order of the coefficient matrix A.
NB : The partitioning blocking factor.
P : The number of process rows.
Q : The number of process columns.
Time : Time in seconds to solve the linear system.
Gflops : Rate of execution for solving the linear system.
The following parameter values will be used:
N : 24000
NB : 1024
PMAP : Column-major process mapping
P : 1
Q : 1
PFACT : Crout
NBMIN : 8
NDIV : 2
RFACT : Crout
BCAST : 1ringM
DEPTH : 0
SWAP : Mix (threshold = 192)
L1 : transposed form
U : transposed form
EQUIL : yes
ALIGN : 8 double precision words

geforce gtx 275 896mb + phenom ii 3.0ghz
geforce gtx 275 = 1404mhz * 240 /8 = 84.240 gflops
phenom ii 3.0ghz = 3000mhz*4*4 = 48 gflops
total = 132.24 gflops
computational efficiency = 81.67/132.24 ~ 62% |
