Subject: Update for Lecture Today

Hello CS 575 Students,

I have spoken to students during office hours, in the halls and via 
email and I feel our lecture in class today should focus on the Diffusion
Report which is due on Wednesday (hard copy in class), web page viewable 
notification by email by midnight.

I realize that I did not provide the UNIX commands to allow those students 
working in C to be able to compare the performance of the Sun  Performance 
Library to the compiled source code from Linpack.
--------------------------------------
Fortran Programmers:

f90 -o fdiff f_diffusion.f -xlic_lib=sunperf    

f90 -o fdiff-sunperf f_diffusion.f sgeco.f sgesl.f blas.f

and you can explore the effect on timing by looking at different 
optimization levels using the 
-O
option on the compile line.
---------------------------------------
C Programmers:

f90 -c sgeco.f sgesl.f blas.f
cc -o cdiff c_diffusion.c sgeco.o sgesl.o blas.o -lm -lF77

cc -o cdiff c_diffusion.c -xlic_lib=sunperf

and you can explore the effect on timing by looking at different
optimization levels using the 
-O
option on each of the compile lines
----------------------------------------

I will be postponing additional lectures from 
III: Shared-Memory Parallel Processors (Ch. 10 and 11) until Wednesday

See you later today
