I am facing a problem in generating xgraph from .tr file. The error message is like this:
Error in file `voip.tr' at line 610:
Unknown line type
Problems found with input data.
The format of .tr file is like this:

I have used command like this in ubuntu in ns2.
xgraph voip.tr
So how can I generate graph from the trace file?
You cannot give your trace file as a direct input to Xgraph. you have to give file with only two lines like
1 5
5 89
8 98 here first row is x axis 2nd is y axis for example save this file as graph.tr
now you can execute using xgraph graph.tr here instead of using random values you have to use your QOS valuse such as number of packets received or sent like that..
xgraph can only be used with .xgr files. While executing the awk command add this (watch for the greater than symbol):
.... > anyname.xgr
Now you can use xgraph to plot, the command is:
xgraph anyname.xgr

This is the webpage I am scraping: http://laxreports.sportlogiq.com/nll/GS2200.html
Below is the code for the spider I created:
import scrapy
class MatchesSpider(scrapy.Spider):
name = 'matches'
allowed_domains = ['laxreports.sportlogiq.com']
start_urls = ['http://laxreports.sportlogiq.com/nll/GS2200.html']
def parse(self, response):
tables = response.xpath('//table')
print(tables)
table = tables[0].xpath('//tbody')
I see 22 tables that have been selected for this XPath expression but my problem is that I don't fully understand how to select each individual table and extract its contents.
I am a beginner in scrapy and after searching online for a solution all I see is how to select the tables using the class or ID which in this case is not an option.
You can do that using only pandas
Code:
import pandas as pd
dfs = pd.read_html('https://laxreports.sportlogiq.com/nll/GS2200.html')
df = dfs[10]#.to_csv('d.csv', index = False)
print(df)
Output:

First run the function b(n):
? b(n) = lcm(vector(n, i, i))/n
After function c(n):
? c(n)=sum(j=1,n,sum(i=1,n,(-1)^(i+j)/(i+j-1)))
Last run d(n):
? d(n)=factor(denominator(c(n))/b(n))~
and test with 202
? d(202)
The result is:
%8 =
[3 7 17 19 31 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293

What indicates the -1 in factoring results?
You try to factor the rational number. Note, type(denominator(c(202))/b(202)) is t_FRAC instead of t_INT because of denominator(c(202))/b(202) = <some big number>/31. So -1 means just -1 power for divisor 31, and no bug is here.
I can't seem to add multiple text strings to a DXF file. It works for when I only have a block of code for 1 line of text. I can't seem to add multiple lines.
I created the code shown below. Any help would be very much appreciated.

The DXF file with the code shown above will not open in AutoCAD and/or Microstation. However it does open in LibreCAD which appears to be more forgiving with syntax.
I'd like it to open in AutoCAD AND Microstation. Any input would very much be appreciated.
Handles (DXF group 5) should be unique within a file.
As such, you should not use the same handle for both text entities:

I have the following code that performs a tiled matrix transpose using shared memory to improve performance. The shared memory is padded with 1 column to avoid bank conflict for a 32x32 thread block.
__global__ void transpose_tiled_padded(float *A, float *B, int n)
{
int i_in = blockDim.x*blockIdx.x + threadIdx.x;
int j_in = blockDim.y*blockIdx.y + threadIdx.y;
int i_out = blockDim.x*blockIdx.y + threadIdx.x;
int j_out = blockDim.y*blockIdx.x + threadIdx.y;
extern __shared__ float tile[];
// coalesced read of A rows to (padded) shared tile column (transpose)
tile[threadIdx.y + threadIdx.x*(blockDim.y+1)] = A[i_in + j_in*n];
__syncthreads();
// coalesced write from (padded) shared tile column to B rows
B[i_out + j_out*n] = tile[threadIdx.x + threadIdx.y*(blockDim.x+1)];
}
Running this code, I get 100% shared memory efficiency in the NVIDIA visual profiler, as I expect. But, when I run it with a 16x16 thread block, I only get 50% efficiency. Why is that? As far as I can tell, no thread in a warp reads from the same bank with this layout. Or am I mistaken?
Yes, you are mistaken.
Considering this (read) access for warp 0 in a 16x16 block:
tile[threadIdx.x + threadIdx.y*(blockDim.x+1)];
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
"index"
Here are the relevant calculations for each thread in the warp:
warp lane: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 23 25 26 27 28 29 30 31
threadIdx.x: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
threadIdx.y: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
"index": 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
bank: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 0
So we see that for this warp, the first and the last thread both read from bank 0. This results in a 2-way bank conflict, 2-way serialization, and 50% efficiency.
I am working on my own DXF writer because I only need certain elements (such as LINE, POLYLINE, POINT an SPLINE).
I started with tfpdxfbridge and the idea was to include SPLINE support too. When I tried to manually add SPLINE to ENTITIES in the *.dxf file, the file is not opened anymore. Example of SPLINE:

Does anybody know what the problem might be or how to make the file work again?
Here is the full file generated with tfpdxfbridge (except the SPLINE part, obviously).

When I try to recover your DXF file I get the following:
Unknown header variable $LINMAX ignored on line 116.
Undefined group code 330 for object on line 1018.
Invalid or incomplete DXF input -- drawing discarded.
In your DXF you have:
330
1F
I see that 330 is included when I do my own spline and save as DXF. But, 330 is according to the documents:
Soft-pointer ID/handle to owner dictionary (optional)
This DXF will recover without any errors:

Perhaps you can do a comparison.
