Hi,<br>
<br>
I have read in the user-manual that parallel sparse matrices are stored in the<br>
manner that the first n1 rows are stored on the process with rank 0 and the<br>
next n2 rows on the process with rank 1 and so on. My question is now, is it<br>
possible to store for example the rows 0 to 24 and 50 to 74 on process with<br>
rank 0 and 25 to 49 and 75 to 99 on process with rank 1 for a 100x100 matrix<br>
with two processes.<br></blockquote><div><br></div><div>No. The effect of a permutation is accomplished with a MaOrdering.</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
