Hello,<br>
I have to perform multiplications of a Hermitian distributed matrix
by a distributed vector.<br>
<br>
Questions:<br>
1) will setting theĀ MAT_HERMITIAN option save the memory of the
matrix storage?<br>
2) will it save me time during the multiplication?<br></div></blockquote><div><br></div><div style>No, it only changes default preconditioner settings (like incomplete Cholesky instead of ILU and symmetric ASM instead of RASM). You can explicitly use the SBAIJ format to use a symmetric format (which saves memory, but it is sometimes slower because it has to communicate twice).</div>
