Also please fine a tentative reading list to help you identifying with
some interesting papers related to class topics.

I have one question.
The assignment says: " "0" will indicate the leftmost column or
topmost row, respectively."
This is regarding the ordered pairs in the input file.
The quoted statement indicates that the ordered pair is < col, row >
I would like to confirm once, if its supposed to be < row, col > or <
col, row >
Thanks.

transpose, which is also acceptable.

I have included a couple of test cases for the programming assignment
in the ASSIGNMENT section
on the course website. Let me know if there are any questions.

I think in this program you are limited with your size of the array.
Because I tried a 50 cross 50 array but it gave error in the runtime.
But when I used an array size of 32 cross 32 then the program worked
fine. Have anybody faced the same problem?

The second programming assignment has been announced today. Briefly,
you will write a program, which runs on the cell simulator, that
multiplies 2 matrices of 1024 by 1024. The goal is to make the program
run as fast as possible by exploring data-level parallelism, SIMD and
communication & computation parallelism, etc. on cell processors. You
have tentatively two weeks working on the assignment. We will announce
a formal specification of the assignment later.
For this assignment, 19 students will be divided into 9 groups. You
will be working on the computers, which have the cell simulator ready,
either in Dr. Gupta's or Dr. Shrivastava's lab. There will 2 to 3
groups working on each computer. You should be able to access these
computers remotely using SSH and Hummingbird/Exceed.
Here is a list of things you need to do now:
1. Form a group of 2 students and send me the names via email. I will
then assign you the computers. There will be only one group of 3, for
which we do FCFS.
2. Start to read materials about cell processors, programming on cell
processors and simulators, and do the cell user guide. You can find
them in the lecture notes on our web page.
3. If you have any questions, discuss them here in this thread
(Programming Assignment) or shoot us email.

1. Install hummingbird and run Exceed.
2. Run SSH; enable TunnelX11 connections under Edit --> Settings -->
Profile Settings --> Connection --> Tunneling.
Let me know if this is not working.

I have the following announcements about PA2.
1. We have set up 2 computers for this assignment. There will be
another computer available at the end of the week. So, there will be 3
groups sharing each computer. Find your group name at
http://impact.asu.edu/cse520fa07/cellsim.html and the computer
resources below. You can modify the password later. When the third
computer is ready, I will move group 7 to there. I am waiting for
information of group 8 and group 9. I will assign the members for the
2 groups unless I receive volunteers by the end of this Saturday.
Computer 1: Located at BY531AB, right in front of the entrance of our
lab.
You can work on it either remotely or locally.
IP address 149.169.177.239
usernames : group1 passwd group1
usernames : group2 passwd group3
usernames : group3 passwd group3
usernames : group7 passwd group7
Computer 2: Remote access only.
IP address 149.169.176.115
usernames : group4 passwd group4
usernames : group5 passwd group5
usernames : group6 passwd group6
2. input and output
Your program should take 3 command line arguments. The first argument
is an integer, e.g., 2, which means the first matrix is an all 2's
matrix (1024x1024). Similarly, the second argument, an integer, is
used to define the second matrix (1024x1024). The third argument is a
string, which is taken as the output file name. For example, you will
run your program like ./myprogram 2 3 myout.
3. what to submit
This is a team assignment. So, each group will submit one program. The
program should be well commented. Besides, you need to submit a
writeup about what technique you applied to make the program faster
and how. Include all your programs in a tar file and submit it to TA
via email before due time with a subject line "cse520pa2:groupname".
Put compile command, known bugs and any other issues you want us know
in the email body.
A formal specification is under preparation and coming soon. You
should start working on the assignment ASAP. Complete references to
cell programing and cell simulator can be found in the materials of
Oct 23's lecture.
Feel free to ask me questions. Enjoy the fun!

We finally get all 3 computers ready. Please check the following link
for group assignments and let me know if there is any question.

If you have any question about the cell simulator and simulator
programming, please direct your question to Amit Pabalkar
<apab...@asu.edu> and cc to me.
Last, I have uploaded a cell broadband engine programming tutorial at
http://impact.asu.edu/cse520fa07/cell/CBE_Tutorial_v2.1_1March2007.pdf.
You can also find the link in the material field of lecture nodes on

I have posted the specification of PA2 on-line. You can find it at
http://impact.asu.edu/cse520fa07/assignment/cse520fa07PA2.doc.
It simply is a summary and clarification of what I have announced
through the blog. But you should have a look at it. As a kind
reminder, PA2 is due on Tuesday, Nov. 20th.
Let me know if you have any questions.

spent on the research project.
I am having a hard time balancing this programming assignment with
preparing my paper presentation, doing the paper critiques, doing the
presentation critiques, paper reading, term project research. Not to
mention my other class assignments.
It just seems like we are trying to do too much in too little time -
especially now that project presentations are to begin on the 27th.
We will spend the next week working on this assignment and then only
have 1 week to finish our term project??
Aren't we going to run out of time from juggling all of these
assignments?

Dr. Gupta has agreed to become PA2 optional. Students who finish it on
time will get extra credits.

Please exit the simulator when they have done working for the day.
This hogs resources and causes inconvenience to all.
