QUESTION
I have encountered a strange problem when accessing an Azure Storage Blob from an Azure Function. I have a Function written in Java which is supposed to download some data from a Blob and then execute a PowerShell command. The PowerShell command can launch another Java application, which accesses the same Blob. I have this process working except for where the Function first downloads the Blob, which always gives a timeout while trying to get the size.
The weird thing is that the Java application launched by the PowerShell command uses the same code to download the Blob and can do so without any trouble at all.
Here is the relevant code snippet:
...ANSWER
Answered 2020-Aug-13 at 22:39Following the exception mentioned in the edit led me to this thread: https://github.com/Azure/azure-functions-java-worker/issues/381.
The issue was that the dependencies for the Function App itself were loading before my dependencies for my code and there is a conflict between them as mentioned here: https://github.com/Azure/azure-functions-java-worker/issues/365.
The solution was to set FUNCTIONS_WORKER_JAVA_LOAD_APP_LIBS = 1 in the Configuration settings of the Function App.

QUESTION
I've been trying to create a 2D map of blobs of matter (Gaussian random field) using a variance I have calculated. This variance is a 2D array. I have tried using numpy.random.normal since it allows for a 2D input of the variance, but it doesn't really create a map with the trend I expect from the input parameters. One of the important input constants lambda_c should manifest itself as the physical size (diameter) of the blobs. However, when I change my lambda_c, the size of the blobs does not change if at all. For example, if I set lambda_c = 40 parsecs, the map needs blobs that are 40 parsecs in diameter. A MWE to produce the map using my variance:

I wrote a C code which reads accumulated bytes from a interface but when this interface goes down it resets and I read 0 again and start all over again reading the accumulated data.
I need to get the real accumulated data from this column in sqlite3.
As an example, if I have the following values (in 10 rows in the table):

I have a.txt file with 400 lines, I need that every 100th line in the sequence it breaks into a new column, so I'd have 4 columns of 100 in a sequence.
The sequence i want is something like: 1->101->201->301 next line: 2->102->202-> etc... Instead im getting 1->2->3->4 next line: 5->6->7->8
The y represents another sequence that I'm working at the same time, where I want to space at every 6 lines read.

QUESTION
I have coded a little MPI program that computes with an iterative scheme on a 2D domain : I apply a filter for each cell values (5 points stencil).
In my code, I split global domain into multiple subdomains depending of number of processes. I take xcell and ycell the size of each subdomain.
Once computation reaches the convergence wanted, I store values for each subdomains into 1D array (see below xtemp array) and after, I use MPI_Gather to collect all these subdomains into 1D final array (xfinal array). In the assignement below (into loop) x0 array represents the 2D subdomain that I want to copy into xtemp 1D array.
Now, I want to know if I apply good coding rules and optimizations (I mean the way to get the best performances from a runtime point of view) with the filling of "xtemp" array in each version (Language C and Fortran90). me is the rank of current MPI process and xs,xe,ys,ye the coordinates of each subdomain. We also have to notice that we take for arrays the convention (i,j) = (rows,columns) in Language C and Fortran90 versions.
I did :

Answered 2017-Dec-31 at 14:03Awhile ago I wrote some preprocessor code to arbitrarily allocate pointer based 2D and 3D arrays of things. I did this to avoid the implicit multiplication required to access members. Note that you can access the array members linearly as well as dimensionally with this method. I hope it helps:
QUESTION
I have a strange result between sequential and MPI version of a small code that computes values on a grid.
The sequential version looks like :
...ANSWER
Answered 2017-Aug-30 at 04:07Array allocation and de-allocation must be symmetrical.
You did declare your 2D arrays as a double **, so these are really arrays of pointers pointing to arrays of double.
In the sequential version, you issued one malloc() for the columns, and then one malloc() per row. your rows will not be in contiguous memory, but this is just fine.
This approach is generally not valid with MPI because you likely pass your 2D array to some MPI functions that expect a contiguous data layout.
So you issued one malloc() for the columns (nothing changed so far), and then one single malloc() for all the rows. And then you constructed the first allocated array with pointers to the second one.
As a consequence, you must issue only two free() when deallocating a 2D array.
So the correct way of deallocating the x array is

My code is posted below. It does exactly what I need it to do.
It reads in a file and plots the data that I need. If I want to read in another file and have it go through the same code, without having to write the whole thing a second time with different variables, is that possible? I would like to store the matrices from each loop.
As you can see the file I get is called: Oxygen_1keV_300K.xlsx
I have another file called: Oxygen_1keV_600K.xlsx
and so on.
How can I loop through these files without having to re-code the whole thing? I then want to plot them all on the same graph. It would be nice to store the final matrix Y and Ymean for each file so they are not overwritten.
...ANSWER
Answered 2017-Jul-19 at 18:18Cell arrays make it very easy to store a list of strings that you can access as part of a for loop. In this case, I would suggest putting your file paths in a cell array as a substitute for the string used in your xlsread call
