RCS Lab Announcements

Hello All,

Here is your weekly reminder that we have the reading group at 3:30 today and the group meeting immediately following it.  I will be on campus from 12-5pm today but I have leave promptly at 5.

Liu will be doing one technical paper today and then he has prepared a CUDA tutorial for us.  Please send me the answer to this question via email:  How does AutoPilot decide to lay out variables? (i.e. on-chip, off-chip, arrays v. scalars).

Also, please post your status as a reply to this message.  Thanks!

Hi All,

Please remember to read the filesystem papers before the meeting today!!  To help you, please answer the following three questions via email directly to me (don’t post the answer on the blog).

1. What is the ciod in the BG/P paper?  What service does it provide or role does it play in the system?
2. Does BG/P run Linux on the PowerPC 450s?
3. How do object-based storage systems get higher bandwidth than server-based storage systems even though both use centralized servers for metadata?

Also, please post your status as a response to this blog entry.

See ya at 3:30 … same Bat Time, same Bat Cave.

I saw Shan sent out an email reminder. Please be sure to add your weekly status report (if you have an account . If you don’t have an account, remind me Wednesday during office hours and we’ll get one created.

Don’t forget the reading group tomorrow.  Two quick questions about the papers being presented:

(1) What is the differnce between for-loops and while-loops in the roccc system?  If no difference, are for loops converted into while loops or the other way around?  If there is a difference, what is the major difference?

(2) Compared to ROCCC, what major philosophical difference is highlighted by the CHIMPs effort?

Hey Everybody,

The Governor is coming on Monday and will probably be visiting our lab. We need to clean up! Floors are going to be cleaned and we need to clear out the recycleables. Boxes with labels are fine but no food should be out. I will learn more at the department meeting at noon.

Ron

This is your reminder that we will have our first reading group today. Andy is presenting two interesting papers from ISCA that have direct bearing on our RCC Project. Please read the papers in advance and send me the answer to these two questions in direct email.

1) in the Saidi paper, how do they validate that their simulations are correct? to what degree is this scientifically sound? is the best one can do?

2) is the Rigel programming model closer to a message-passing model or a shared memory model?

For the group meeting, please reply to this announcement with your status report.

Thanks!

Ron
