Parallel Computing Research Paper
The current trend in microprocessor technology is to take advantage of Moore's Law (which states that the number of transistors per a certain area on the chip will double approximately every 18 months), to include an increasing number of processor cores in a single integrated circuit chip. Here's an interesting article by a group of Berkeley researchers that discusses parallel computing and why continuing to double the number of processor cores is likely to meet with diminishing returns.
A couple quotes I found interesting:
"Multicore will obviously help multiprogrammed workloads, which contain a mix of independent sequential tasks, but how will individual tasks become faster? Switching from sequential to modestly parallel computing will make programming much more difficult without rewarding this greater effort with a dramatic improvement in powerperformance. Hence, multicore is unlikely to be the ideal answer."
"Since real world applications are naturally parallel and hardware is naturally parallel, what we need is a programming model, system software, and a supporting architecture that are naturally parallel."
This paper has me thinking about parallel programming models and the meaning of "naturally parallel." For example, there are existing languages, such as Verilog, that are used to describe hardware systems and, as such, must be naturally parallel. However,[url=http://www.holisteroutlet.cc]hollister femmes[/url], I certainly wouldn't want to code application software in languages this way. Instead, we'd want a naturally parallel language at a much higher level of abstraction. Even so, can we ever remove the essential complexity involved in coordinating multiple simultaneous threads of execution? Also, must we, as developers, forever need to explicitly parallelize applications, or should we eventually be able to work in a comfortable sequential programming model and have tools analyze the inherent parallelism and take care of the translation automatically?
Perhaps these issues may be a symptom of relying on imperative programming languages, and the solution will lie instead with declarative programming languages. To take advantage of the increasing number of processor cores we may need to move from specifying how to perform a computation to specifying what should be computed. It'll be interesting to see what develops in a few years in this area. After all, 16 and 32way processors are not that far off and, if this paper is right, we will experience diminishing returns at that point and software developers will be in for some big changes.

For the environmental management and strengthen the construction of the project,[link widoczny dla zalogowanych], to promote the rapid, healthy, sustainable development of county economy.
is a strict approval mark.In strict accordance with the "Environmental Impact Assessment Law", "construction project environmental protection management regulations" and other documents, precondition regional pollutant emissions targets as the project EIA approval, to strengthen the new, change, expansion project approval,[link widoczny dla zalogowanych], services, prevent inconsistent with national industrial policies and environmental requirements of the project;
two is strict construction points.The establishment of dynamic management of project construction process, to further strengthen the environmental classification tracking supervision, to establish a construction project dynamic management accounting, the implementation of the whole process from the construction to the tracking and supervision of production, and actively carry out special rectification construction projects and the "look back" activities, to ensure that the construction project environmental protection facilities with the main project design, construction at the same time, at the same time at the same time put into use;
three is a strict approval mark.Regularly meet the acceptance conditions of the construction project, strengthen the completion acceptance of environmental protection management of construction unit, not the implementation of environmental protection "three simultaneous" system, "long procrastinate not to experience", "long try not experience" and not by the environmental protection acceptance or unqualified acceptance and arbitrarily put into production and operation, take effective measures, shall be ordered to a deadline for rectification,[link widoczny dla zalogowanych], 2011 in May two period project,[link widoczny dla zalogowanych], Dragon Pearl Plaza area Chongli county first middle school dormitory, multi-function hall for completion acceptance of environmental protection facilities, promote enterprises to standardize the operation.Four is the strict service gateway.To enhance the service concept, take the "early intervention", "nanny service law", "simplify the procedure law" to help enterprises improve the project approval of related work.1, early intervention, the Bureau leadership led the relevant professionals, deep into the key enterprises and township door-to-door to understand the situation of construction plans and construction projects, from the past to wait for approval to the active site of examination and approval, which shorten the approval time and avoid the problem of environmental protection, causing unnecessary losses.2 nanny services, the county key projects and reporting,[link widoczny dla zalogowanych], approval of the project, led by the Bureau of the main leaders,[link widoczny dla zalogowanych], take deputy, run do,[link widoczny dla zalogowanych], lead, arranged the way to full nanny service to the project, help enterprises to apply for the EIA approval procedures for the first time, to ensure the project examination and approval in the shortest time limit.3, simplify procedures,[link widoczny dla zalogowanych], cancel the precondition of all project environmental impact assessment and approval of new projects, the EIA, the EIA County Bureau do not charge a fee.Up to now, a total of approval,[link widoczny dla zalogowanych], business tourism projects, Chongli County, Zhangjiakou City Founder of real estate development projects, Chongli County, the Four Seasons Resort project 18,[link widoczny dla zalogowanych], project total investment of 57075967000 yuan, 127470000 yuan investment in environmental protection.Among them: submitted to the Municipal Environmental Protection Bureau for examination and approval of the 8 projects, approval of the 10 projects,[link widoczny dla zalogowanych], according to the requirements of environmental protection and strict implementation of the "environmental impact assessment" system,[link widoczny dla zalogowanych], do the standard construction, not omission and ultra vires approval of the phenomenon, to ensure that the construction project EIA approval rate and environmental protection facilities "three simultaneous" implementation rate up to 100%.
