Answer:
CPU need 50% much faster
disk need 100% much faster
Explanation:
given data
workload spend time CPU = 60%
workload spend time I/O = 40%
achieve overall system speedup = 25%
to find out
How much faster does CPU need and How much faster does the disk need
solution
we apply here Amdahl’s law for the overall speed of a computer that is express as
S = .............................1
here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component
so put all value in equation 1 we get
S =
1.25 =
solve we get
k = 1.5
so we can say CPU need 50% much faster
and
when f = 0.4 and S = 125 %
put the value in equation 1
S =
1.25 =
solve we get
k = 2
so here disk need 100% much faster
Answer:
Explanation:
K- is the working procedure:
It takes n no. of predefined cluster as input and data points.
It also randomly initiate n centers of the clusters.
In this case the initial centers are given.
Steps you can follow
Step 1. Find distance of each data points from each centers.
Step 2. Assign each data point to the cluster with whose center is nearest to this data point.
Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.
repeat above steps until the center in previous iteration and next iteration become same.
A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)
Centers are X1=A1, X2=B1, X3=C1
A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.
