[FlopCpp] Re : Re : FLOPC++ in C++/CLI with VS2005 does not work.

[yo yo]

I finally managed to make it work with C++/CLI. I just put the code directly into my program instead of using a lib file, and it worked.
I think the issue was a problem of linking probably due to a wrong version of the header files compared to the lib.

Thanks for your help.
YO.

I tried that but I still have the same memory issue.
GetEmpty does not seem to be executed because cardinality of supposed
 empty sets is 170 million this time.

In a case like this I've tended to use subsets to sparsely allocate.

    MP_set PERIODS(numPeriods);
    MP_set PRODUCTS(numProducts);
    MP_set SITES(numSites);
    MP_subset<3> my_subset(PERIODS,PRODUCTS,SITES);
    MP_data availability(my_subset);

(I also then use this subset on my variables)

Hello,

I am having a problem with flopc++ used in Microsoft C++/CLI 2005.
The MP_data declaration fails because it try to allocate a huge amount
 of
memory. (4 billions bytes).

    MP_set PERIODS(numPeriods);
    MP_set PRODUCTS(numProducts);
    MP_set SITES(numSites);
    MP_data availability(PRODUCTS,SITES,PERIODS); fails here.


MP_data(const MP_set_base &s1 = MP_set::getEmpty(),
        const MP_set_base &s2 = MP_set::getEmpty(),
        const MP_set_base &s3 = MP_set::getEmpty(),
        const MP_set_base &s4 = MP_set::getEmpty(),
        const MP_set_base &s5 = MP_set::getEmpty()) :
        RowMajor(s1.size(),s2.size(),s3.size(),s4.size(),s5.size()),
        S1(s1),S2(s2),S3(s3),S4(s4),S5(s5),
        v(new double[size()]), manageData(true)     <<<<<fails here on
 new
double[size()].
        {
        initialize(0);
        }

I tried to debug with VS2005 and apparently the 2 last sets that are
supposed to be empty got a cardinality of 160 million which cause the
 size
to be huge.

To make the flopclib compatible with Managed code in .Net I have been
obliged to compile with /MD switch instead of MT.
I have also noticed that between the exemple "Transport" and this code,
VS2005 does not follow the same path. It looks like the getEmpty code
 is
not executed or it is after the size in rowmajor is set.

Any idea of what is causing the problem.?
Thanks,
YO.
