Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We can now use the cublasSaxpy function."

A block of code is set as follows:

cublas.cublasDestroy(handle)
print 'cuBLAS returned the correct value: %s' % np.allclose(np.dot(A,x), y_gpu.get())

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

def compute_gflops(precision='S'):

if precision=='S':
    float_type = 'float32'
elif precision=='D':
    float_type = 'float64'
else:
    return -1

Any command-line input or output is written as follows:

$ run cublas_gemm_flops.py

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this.
