PARDISO Phases called in different routines,Mem leak?

Hi

I am calling pardiso  with c/c++. for that I packed all phases of pardiso  in a library  , but splitted into different soubroutines using *pt and *iparm as  global variables within that file/library (see the pseudo code below)

library.c:

void *pt[64]
MKL_INT  iparm[64]

phase_init( ... ){
....
}

phase_11(a, ia, ja){
....
}

phase_22(a,ia,ja){
   ....
}

phase_33(a, ia,ja, double* x, double* b){
...
}



 

After that with the client code call phase 33 passing x and b, as many times as I want (the problem is actually I can call only one RHS at once , since a RHS will be calculated with previous RHS's)

The code is working well , but  memory is increasing uncrontrolled , I read that  one should not  modify pt after the first phase since a severe memory leak might occur, which is my case. But I am not modifiying pt , I am  just passing it from function to function as global, and I dont see why pt have to be always local to the function that calls it.

I am using mkl 11.2 with gcc linking static w/o multi-threa.

Hi,

Which update of MKL 11.2 you use? If not MKL 11.2.3 could you check to run your code with this update to verify that issue is fixed?

Thanks,

Alex
