Assigned Readings:Chapter 16. Organizational CultureChapter 17. Organizational Change and Stress ManagementInitial Postings: Read and reflect on the assigned readings for the week. Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.Also, provide a graduate-level response to each of the following questions:

1. Technological advances in society have been shown to cause organizational stress. Why is this the case, given that changes in technology usually means work is less complicated or time consuming? 

[Your post must be substantive and demonstrate insight gained from the course material. Postings must be in the student’s own words – do not provide quotes!]  [Your initial post should be at least 450+ words and in APA format (including Times New Roman with font size 12 and double spaced). Post the actual body of your paper in the discussion thread then attach a Word version of the paper for APA review]

1. Why are large-scale disasters of particular concern when choosing off-site storage locations for data backups and equipment?

2. What are the primary goals associated with the recovery phase? restoration phase?

The genome of an organism can be expresses as some number G of

"base pairs" (see http://en.wikipedia.org/wiki/Base_pair). Typical

sizes of various genomes are given in (http://en.wikipedia.org/wiki/Genome).



String matching can be used to find particular sequences in a

genome. Several string matching algorithms are described

in (http://en.wikipedia.org/wiki/String_matching)



Consider a program to find to find if a particular sequence of

base pairs is found in a genome, and if so, where and how

many times.



Your program will run on a cluster with 

the following properties:



Number of nodes - 20



  Number of processors per node 16 2.6 GHz Xeon

  Memory per node               16 GB

  GPU - 2 (NVIDIA CUDA) per node, 1024 stream processors and 4GB RAM, running at 1.5 GHz 

  local drives 1 T SATA , 6 GB/sec

  NFS drive 10TB  RAID, bandwidth limited by network

	                

Switched Ethernet network

Latency               L = 20 microseconds

Bandwidth             B = 1Gb/sec == 100 Mbytes/sec for messages

			   larger than 32Kbytes





You may not need all the above information. If you feel you need some other system 

property, feel free to assume some reasonable value (Try Wikipedia)



Assume the genome you are exploring and the sequence you are

trying to find, are both initially files on the NFS disk.



Deliverables:



1. Parallel String Match algorithm - in MPI, OpenMP, CUDA or some

combination of these. Description in English and/or pseudocode is

sufficient. Is yoyur algorithm data parallel, task parallel or both? 



Describe data transfer during computation (disk to program, process to process,

CPU - GPU and node - node). Describe how data is partitioned between processes, 

shared between processes, or replicated at each process.



2. You may not need all the hardware available for your algorithm. You may use the

entire cluster or any part of it. Describe what resources your algorithm will use to 

execute. Explain your choice.



3. Estimate how your algorithm would perform on the computer

system described above. Consider:

    a. Complexity; communication costs.

    b. Is there some file size (in bytes, number of elements, or both)

that is too small for your algorithm to work efficiently? Given the wide range of genome

sizes (see http://en.wikipedia.org/wiki/Genome), is there some range of size that you expect would

be best for your algorithm?

    c. How much speedup would you exepect on the given hardware as compared to running

on a single CPU? Justify your answer
