SKA Radio Telescope I Get, But Why Megadata?

12 April 2012

DOME: IBM and ASTRON’s Exascale Computer for SKA Radio Telescope contains a picture that in turn contains the word megadata. My last posting focused on an article that used the word nanodata. I just didn’t get what nanodata meant, but I sort of understand megadata. The following is a quote from the SingularityWeblog.com posting:

The SKA is an international consortium to build the world’s largest and most sensitive radio telescope. Scientists estimate that the processing power required to operate the telescope will be equal to 100 million of today’s fastest desktop computers.

I understand the use of megadata to describe lots of data, but I would have used yottadata.

Borrowing from Pink Floyd’s “Comfortably Numb”… Is there anybody out there?

20 Petaflops Coming Soon

31 March 2012

[1 April 02012]
Three years ago, on 1 April 02009, I gave a talk titled 20 Petaflops by 02012. [Yes, I used a 5-digit year.] First quarter of 02012 has ended and as far as I know our computing world has not hit 20 petaflops, but the next TOP500 list doesn’t come out until June. Regardless, I am 99.999% confident that 20 petaflops in 02012 is going to happen primarily because of what IBM announced four months ago.

IBM issued a press release titled IBM Announces Supercomputer to Propel Sciences Forward having the sub-title Blue Gene/Q tackles major challenges of the day, delivers up to 100 petaflops at peak performance.

“When it is fully deployed in 2012 at Lawrence Livermore National Laboratory (LLNL), the system, named ‘Sequoia’, is expected to achieve 20 petaflops at peak performance, marking it as one of the fastest supercomputers in the world.”

The TOP500.org issued the following press release: Japan’s K Computer Tops 10 Petaflop/s to Stay Atop TOP500 List. Japan’s K computer was benchmarked at 10.51 petaflops.

AzGrid::Talk::20 Petaflops in 02012

Two years earlier I gave a talk sub-titled Computing in the 21st Century. During that talk I stated the following: “The next era of computing is the era of High-Performance (Productivity) Computing (HPC).” In addition, during the talk I indicated that peta-scale computing was scheduled to occur in 02008. TOP500.org posted the following on 18 June 02008: “With the publication of the latest edition of the TOP500 list of the world’s most powerful supercomputers today (Wednesday, June 18), the global high performance computing community has officially entered a new realm–a supercomputer with a peak performance of more than 1 petaflop/s [1.026 petaflops]
