's sixth generation mainframe since 1994 -- will give the company a head start in sales over some even more powerful machines due out in September from the Hitachi Data Systems.
A Mainframe 's Little Sibling.
Hiraguri said that he expected Fujitsu would install 300 of its newest mainframes over the next three years.
In reality, speed ratings of mainframes are about as meaningful as the top speed shown on the speedometer of a sports car: it may look impressive, but no one actually drives that fast. With mainframe computers, the conversation is often about moving applications off of them, but are you saying enterprises are investing in new mainframes .
We just recently signed a deal for new mainframes for the next five years.
I think a lot of big companies are continuing to invest in mainframes .
The Social Security Administration is bracing for massive increases in data that will tax its mainframe capacity following the implementation of the new Medicare drug benefit plan and the retirement of the baby boomers.
Mainframes, personal computing, and the Internet have all transformed the world of business technology for both enterprises and technology vendors.
Rather than rip-and-replace, optimize your mainframe MIPS for key applications and understanding where you can redeploy MIPS-heavy workloads to alternative, more cost-effective platforms without introducing significant risk.

In science:

Example of a bad generator: RANDU RANDU is a linear congruential PRNG of the Park-Miller type that was installed as the standard generator on IBM mainframe computers in the 1960s.
Random Numbers in Scientific Computing: An Introduction
The cost-benefit remains but the additional up-front cost typically affords excellent hardware redundancy and maintenance programs that used to only be associated with traditional supercomputers and mainframes.
Cluster Computing White Paper
These systems are a logical extension of the batch job environments on old mainframes.
Cluster Computing White Paper
It had to be done on fairly expensive general purpose mainframe computers.
A Review of VLBI Instrumentation
BOINC is “a software platform for distributed computing using volunteered computer resources.” That is, you can download BOINC software to your home computer (or mainframe) and join any of a number of worthwhile pro jects via the internet.
Astrophysics in 2006
Another well-known example is the zSeries mainframe concept , combining different processing units on one multi chip module with a shared L2 cache.
The Multi-Core Era - Trends and Challenges
CC independence made its start as an omnipresent feature of mainstream technology with mainframe business computing and is now also a dominant feature for personal computing.
Informal Control code logic
Utilizing modern programming languages and paradigms for developing complex distributed applications does not only bear advantages. Developing applications on workstations but deploying them to servers or mainframes is prone to compat ibility and scaling problems.
Improving the Technical Aspects of Software Testing in Enterprises
Distributed systems offer a better price and performance than mainframes. A distributed system has more total computing power than a mainframe. If one machine crashes, the system as a whole can still survive in distributed system.
An Overview of Portable Distributed Techniques
The total CPU time on the three IBM compatible mainframes was approximately 400 hours.
Perturbative QCD Calculations of Total Cross Sections and Decay Widths in Hard Inclusive Processes
See gr-qc/9803005 24 It is of historical interest to note that the fastest time for the Bondi test quoted in Table 3 (on dedicated mainframe computers of the era) is typically of the order of twenty times slower than a modest contemporary PC with general purpose software.
