===============================================
STREAM is the de facto industry standard benchmark
for measuring sustained memory bandwidth.
Documentation for STREAM is on the web at:
http://www.cs.virginia.edu/stream/ref.html
===============================================
NEWS UPDATE: January 17 2013:
Version 5.10 of stream.c is finally available!
There are no changes to what is being measured, but
a number of long-awaited improvements have been made:
* Updated validation code does not suffer from
accumulated roundoff error for large arrays.
* Defining the preprocessor variable "VERBOSE"
when compiling will (1) cause the code to print the
measured average relative absolute error (rather than
simply printing "Solution Validates", and (2) print
the first 10 array entries with relative error exceeding
the error tolerance.
* Array index variables have been upgraded from
"int" to "ssize_t" to allow arrays with more
than 2 billion elements on 64-bit systems.
* Substantial improvements to the comments in
the source on how to configure/compile/run the
benchmark.
* The proprocessor variable controlling the array
size has been changed from "N" to "STREAM_ARRAY_SIZE".
* A new preprocessor variable "STREAM_TYPE" can be
used to override the data type from the default
"double" to "float".
This mechanism could also be used to change to
non-floating-point types, but several "printf"
statements would need to have their formats changed
to accomodate the modified data type.
* Some small changes in output, including printing
array sizes is GiB as well as MiB.
* Change to the default output format to print fewer
decimals for the bandwidth and more decimals for
the min/max/avg execution times.
