当我使用多个选项(例如不同的问题大小等)运行 HPL 时,基准测试会在系统上执行多次运行。在我的例子中:
- 多个NBMIN
- 多个 BCAST
- 多重深度
- 等等
然后,当我查看运行的单个输出文件时,我不明白如何区分这些输出。在我的示例中,我如何知道哪个变体WR01R2C4
or WR01R2C8
orWR03R2C4
是?
输出提供了一个带有编码变体的线索,但我找不到任何关于如何解码它的信息。
有人知道吗?
这是我的输出文件的片段......
(另一方面:在stackoverflow上我的代码块中是否可以选择突出显示(即加粗)文本?)
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 : 9000
NB : 640
PMAP : Row-major process mapping
P : 3
Q : 3
PFACT : Crout
NBMIN : 4 8
NDIV : 2
RFACT : Right
BCAST : 1ringM 2ringM
DEPTH : 0 1
SWAP : Mix (threshold = 60)
L1 : transposed form
U : transposed form
EQUIL : yes
ALIGN : 8 double precision words

- The matrix A is randomly generated for each test.
- The following scaled residual check will be computed:
||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N )
- The relative machine precision (eps) is taken to be 1.110223e-16
- Computational tests pass if scaled residuals are less than 16.0
