Hello,<br><br>I have been have problems using Mumps on a large (O(1M) sparse martrix) on multiple cores. I first used the Petsc interface but it would hang sometime.<br>Therefore, I wrote it now using MUMPS's C interface. <br>
The code works for one or two cores, but again hangs in the factorization stage using 4 cores.<br><br>Note: That mumps, BLASC, and Scalpack was installed with petsc using --download<br>Compiled using intel 11.1<br><br>If anyone has any ideal, I would really appreciate some feedback.<br>
<br>Thank you<br><br>Josh<br>
