Thanks for the kind response. I am building slepc 3.7.3 and when I configure –with-64-bit-indices=1, I am getting the following error.<br>
<br>
./configure --with-64-bit-indices=1 --prefix=/lustre/atlas/proj-<wbr>shared/csc209/ramki/slepc<br>
ERROR: Invalid arguments --with-64-bit-indices=1<br>
Use -h for help<br></blockquote><div><br></div><div>I think you need to do "configure --with-64-bit-indices=1" for PETSc (Not SLEPc).<br><br></div><div>Fande,<br><br></div><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">

When I run ./configure –h, I am getting the following options. Let me know if I am missing something.<br>

The resulting matrix has something like<br>
<br>
>>> 119999808*119999808*1.e-6<br>
14,399,953,920.036863<br>
<br>
nonzero entries. It is possible that some integer operations are overflowing since C int can only go up to about 4 billion before overflowing.<br>
<br>
You can building with a different PETSC_ARCH value using the additional ./configure option for PETSc of --with-64-bit-indices and see if the problem is resolved.<br>

This is a 1D row distributed sparse uniform random matrix with 1e-6 sparsity over 36 processors. It works fine for smaller matrices of sizes with 1.2 million x 1.2 million. Let me know if you are looking for more information.<br>
