compiler construction - Difference between shareable and non-shareable libraries for linking -


I am currently installing on a cluster. For Configure , a parameter is - enabled - , "MPIH is built when a shared library is created" (page 9). It works as an example only, my question is MPIG is an agnostic: is there any difference between "shareable" and "non-shareable" libraries?

By now I have assumed that a library (static), dynamic, late linking), but

  • Are there different library types?
  • If yes, what's the difference, especially the technical differences? Are non-shareable libraries compiled differently or have less functionality?
  • If not, what about MPEEH installation manual entry?

    Thank you!

    There is a difference between "shareable" and "non-shareable" libraries

    Yes: can be shared between different executions using shared libraries.

    Archive libraries (as opposed to shared) and can be shared only when using multiple instances of that executable, but not between different executives.

    Edit:

    There is a lack of use of shared libraries

    There are several:

    • Calling in the shared library, as well as in the library, calls and access to global data can be a bit slower (usually 1-2%, but can be up to 10% in extreme cases). There are, but they are not trivial.
    • Using shared libraries requires that you target the both main executables, and all shared libraries (and the right of these shared libraries Version) is needed once it reaches the number 100 libraries it can be an important problem.
    • The use of shared libraries opens doors for "" and many odd errors when your shared library of your development system does not match the version versions of your production / cluster / customer system.

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...
