## DESCRIPTION

### clBLAS client command line options:

- **-h** \[ **--help** \]

  produces this help message

- **-g** \[ **--gpu** \]

  Force instantiation of an OpenCL GPU device

- **-c** \[ **--cpu** \]

  Force instantiation of an OpenCL CPU device

- **-a** \[ **--all** \]

  Force instantiation of all OpenCL devices

- **--useimages**

- **-n** \[ **--sizen** \] arg (=128)

  Number of columns in B and C

- **-k** \[ **--sizek** \] arg (=128)

  Number of columns in A and rows in B

- **--lda** arg (=0)

  First dimension of A in memory.\
   if set to 0, lda will default to M (when transposeA is "no transpose") \
   or K (otherwise)

- **--ldb** arg (=0)

  First dimension of B in memory.\
   if set to 0, ldb will default to K (when transposeB is "no transpose") \
   or N (otherwise)

- **--ldc** arg (=0)

  First dimension of C in memory.\
   if set to 0, ldc will default to M

  Offset of the matrix A in memory object

- **--offBX** arg (=0)

  Offset of the matrix B or vector X in memory object

- **--offCY** arg (=0)

  Offset of the matrix C or vector Y in memory object

- **--alpha** arg (=1)

  Specifies the scalar alpha

- **--beta** arg (=1)

  Specifies the scalar beta

- **-o** \[ **--order** \] arg (=0)

  0 = row major, 1 = column major

- **--transposeA** arg (=0)

  0 = no transpose, 1 = transpose, 2 = conjugate transpose

- **--transposeB** arg (=0)

  0 = no transpose, 1 = transpose, 2 = conjugate transpose

- **-f** \[ **--function** \] arg (=gemm)

  BLAS function to test.\
   Options: gemm, trsm, trmm, gemv, symv, syrk, syr2k

- **-r** \[ **--precision** \] arg (=s)

  Options: s,d,c,z

- **--side** arg (=0)

  0 = left, 1 = right.\
   only used with \[list of function families\]

- **--uplo** arg (=0)

  0 = upper, 1 = lower.\
   only used with \[list of function families\]

  0 = unit diagonal, 1 = non unit diagonal.\
   only used with \[list of function families\]

- **-p** \[ **--profile** \] arg (=20)

  Time and report the kernel speed (default: profiling off)

- **--roundtrip** arg (=noroundtrip)

  Including the time of OpenCL memory allocation and transportation\
   Options: roundtrip, noroundtrip(default)

- **--memalloc** arg (=default)

  Setting the memory allocation flags for OpenCL\
   no effect if roundtrip time is not measured\
   Options: default(default), alloc\_host\_ptr, use\_host\_ptr, \
   copy\_host\_ptr, use\_persistent\_mem\_amd, rect\_mem
