Determining Your Processor
This section indicates how you can determine what type of processor your
computer has.
ALPHA. Enter the command
/usr/sbin/psrinfo -v
which returns something like
Status of processor 0 as of:05/03/01 17:16:55
Processor has been on-line since 04/20/2001 14:09:31
The alpha EV4.5 (21064) processor operates at 233 MHz,
and has an alpha internal floating point processor.
The number in parentheses on the third line, in above example (21064), is the
number you are interested in.
GLNX86. Enter the following command
cat /proc/cpuinfo
and look for the following fields in the output (values may vary from the
example below)
vendor_id :GenuineIntel
cpu family :6
model :8
model name :Pentium III (Coppermine)
stepping :1
Match up this information with the table in <MATLAB>\bin\glnx86\blas.spec.
Note Some versions of glibc 2.1.x have problems with environment variables
(and the ability to reliably query them) from within shared library
init
functions. To take advantage of the
BLAS_VERSION feature, you may need to
upgrade your machine to glibc 2.2.
