challenging: program stoped on a procedure launched by call system()
Dear friends, my issue is the following: I would like to close a "program" (named P1, for semplicity), launched by a my exe (P2) (which uses "call sysemt ('P1.exe input_file').) This software (P1), of which I haven't the source, to be closed (and return the control to P2), needs to push a... -
change a formula or expression without change the soure
Dear NickFork, thanks for your reply. I know I used some time for the last post, but I'm happy that at least you saw what i did, becouse there are interesting passages as the possibility to convert an character in to an internal varible (by using pointers and an internal data-base ). Clearly... -
change a formula or expression without change the soure
watch out in the module, at the end, i forgot to dellocate and nullify the pointers! nullify (P_out_parz) deallocate (P_out_all) ciao, Albi73 -
change a formula or expression without change the soure
Dear friends, I ask perdon for the late in reply, but i used some time to solve the problem. What I really wanted was a way where one doesn't need to compile again a dll. or some lines of code. From the GerritGroot entry, that made me ring a bell, i started to look for some preexisting fortran... -
change a formula or expression without change the soure
Dear friends I'm using a code, which reads some parameters from an external file (unit=100); These parameters are inserted into an expression (or equation) and the result of the expression tells to the code how it proceed. I'd like to be able to change the expression without change the source... -
two pointers into one
Thanks dear FJacq, again your reply turn on the light of my brain (and it's not so easy, it is really a black box :) ). This night going to home I was thinking this soluction, but I didn't understand the real motivation, which is that: poiter, like array, have to respect the costant stride. So... -
two pointers into one
Hi dear friens, I have the following problem that i think might be a solution suppose to heve the following code: [code/] real, dimension(1:3), target :: max real, dimension(1:4), target :: min real, dimension(:), pointer :: p1,p2 p1=>max p2=>min [/code] so far it is all ok. What i'd like... -
how well structuring an input file ( by pointers ?)
Hi guys, i'm breaking my head with a problem that i'm not able to solve!; I have a doubt it could be easier than it seems, but i can't find the way i'm developing an user interface for a genetic algorithm. In this GA there are some genes, that pilot an external code. Up today I've changed the... -
write(unit,namelist) can I controll the output format!?
on linux absoft 8.0, lahey 8.1, gfortran 4.1 on windows lahey 5.6 I think I have tested the write namelist on windows (lahey) and on linux with lahey 8.1, gfortran 4.1 not with absoft. Usualy I work with F95. Any way i have never find any kind of possible controll on the format. I have seen... -
write(unit,namelist) can I controll the output format!?
I'd like to be able to control the output format when I write an namelist on a file. I call a compiled code from my fortran code. This compiled code needs an input file , which is clearly wrote by using namelist. My code has to charge the variables from this input file, works on them and at... -
MPI_TYPE_CERATE_STRUT to pass a derived type with allocatable array
Dear Fjacq, at the end I have to close this story, also becouse you was very kind gave me a lot of help. After i solved all what was solvable with your help, the problem came from the MPI library. So for who will use l"am-mpi" watch out, because they have some bugs by using mpi_structure and... -
MPI_TYPE_CERATE_STRUT to pass a derived type with allocatable array
Dear Fjacq, I have read your reply; what you say make sense, like ever; although I have checked that the addresses of the different elements in cromF and in cromF2 shown the same gap from the base to the elements. Clearly this case could be a lucky case and I'm sure that your suggestion remains... -
MPI_TYPE_CERATE_STRUT to pass a derived type with allocatable array
ok i have a lot to learn! anyway in the blockcounts(1:3), the "mpi call" asks the gap from the precedent adress, not the starting position so if i start from position "this%gene(1)" i obtain: blockcounts(0)=0 blockcounts(1)=-244 blockcounts(2)=-246 probably one needs to consider two differents... -
MPI_TYPE_CERATE_STRUT to pass a derived type with allocatable array
Dear Fjacq, I'm grateful to have met a preparate person like you! so i go ahead with my questions :) What you say makes sense and more, but let me try to understand as better I can; what exactly do you mean for descriptor in the last sentence? is it the name of the derived type, the clearly... -
MPI_TYPE_CERATE_STRUT to pass a derived type with allocatable array
I apologize for the length of the title :) In the code that i'm modifing I have created a class that contains a derived type that in turn contains an allocatable vector of reals (crom) (further :idon (real) and pos(integer)): module class_crom use random_N type crom sequence...
