python - How to determine whether a memory page is mmaped in C -


I would like to know one way to determine whether an indicator is from an MMAPD memory page.

To use msync () on an indicator on StackOverflow it determines whether it passes or not but what I found msync () will be as long as the indicator page size There is a multi, no matter the page or mmaped.

I know the beginning of the page by the macro: 

  #define align_to_page (addr, pagesize) (& addresses amp; ~ (pagesize - 1))   
 Please help me, I'm working on it blocking here for a long time and here. Thanks in advance :)  
 Background: I am developing an extension for Python and Namchi. In some tasks, it is a general numpy.ndarray and a numpy.memmap that is created by mmap to distinguish a subclass of numpy.ndaraay with its data buffer () supported by a file on the disk.  
  
 
 
 All non-blank process address space  mmap  ed is either  Mmap  syscall or indirectly using  brk  /  sbrk  through syscalls  
 You might be able to separate another  numpy  arrays to find the path.  
 The documentation says that these arrays may have extra properties  file name ,  offset  and  mode  You may use it to find out whether an array is supported by the file or not.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
