High performance Linkpack
hello everyone ,
Im new to HPL. i wanted to know whether High performance linpack solves linear
system of equations for single precision airthmatic on LINUX.
it works for double precision , so is there any HPL version which is for single precision.\
thanks .

FLOAT(3) BSD Library Functions Manual FLOAT(3)
NAME
float -- functions with single-precision floating-point arguments
DESCRIPTION
The following functions are available in single precision. The functions conform to the ISO/IEC 9899:1999(E) standard. They are similar to
the corresponding double-precision functions (which have the same name, without the "f" at the end). The double-precision functions have
their own pages. Wherever the double-precision functions use a double-precision floating-point value (as an argument or return value), these
functions use a single-precision floating-point value.
To use these functions you must add an additional flag to the link step that produces the executable binary. Specify "-lmx".

The following functions are also available in single precision. The functions conform to the ISO/IEC 9899:1999(E) standard. Each one has its
own page, which it shares with its corresponding double-precision function (which has the same name, without the "f" on the end). The page
can be found under both names.
You do not need to specify the "-lmx" flag to use these functions.
