performance - Estimate parallel efficiency using unicore processor -


We know that parallel efficiency of a program running on a multicore system can be calculated as speed / N Where N is the number is definitely So to use this formula first we need to execute the code on a multicore system and need to know the speed

I would like to know that I do not have a multicore system, so what is possible Can the speed of code given on a multicore system be estimated by executing it on a Unicorn processor?

I have access to the functionality counter (instructions per cycle, number of caches, number of instructions, etc.) and I only have the binaries of code.

[Note: I guessed

P>, especially about the bit.

To determine how much you can speed up your program, you need to know how some parts of the program can be benefited by parallel and which part should be executed sequentially To If you know that, and if you know that when you take serial and parallel parts (personally) on a processor, you can guess how fast the program will be on many processors.

From your description, it seems that you do not know which parts can use parallel processing and which parts to be executed sequentially. So it will not be possible to estimate the running parallel time.

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...
