In Lapack. cc, following sections should be called in each time.
{{{
218 #pragma omp critical
219 {
220 if(!this->calculatedDsysvBlockSize){
221 lwork = -1;
222 double tempWork[3]={0.0, 0.0, 0.0};
223 dsysv(&uplo, &size, &nrhs, convertedMatrix, &lda, ipiv, tempB, &ldb, tempWork, &lwork, &info);
224 this->calculatedDsysvBlockSize = true;
225 this->dsysvBlockSize = tempWork[0]/size;
226 }
227 }
}}}
In, Lapack_GNU.cpp following sections should be called in each time.
