c - "Segmentation fault" with large files -


I am trying to replace a graph using ASCII DIMACS format using this tool ??? . Unfortunately, this does not work with large files (& gt; 2GB); Output is "segmentation fault (core dump)". How can I fix this problem? #define MAX_NR_VERTICES 10000 genbin.h

In

In addition, it does not check any errors whether it is read in the corner from the file or is more than this size, it just writes invalid memory if the file contains the serial number 10000 or more

Perhaps your "big file" can contain more than 10,000 characters?

This code generally has very little error-checking, there are many things you can do in your input file which will cause this code to write an invalid memory without any warning May be.

If you want to modify this code to work with more than 10,000 characters, then I recommend that bitmap once you nr_vert read and validated, and added error-checking in every read operation. (And fix line 77, in which an incorrect attempt has been made to check the error).

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...
