spmvtest3b(1)

💖 spmvtest3b — the SpMV benchmark bestie 💖

ok so real talk, this is a page from the Utility Commands manual, and it's all about spmvtest3b. welcome to the group chat, bestie 🫶

---

✨ NAME ✨

spmvtest3b — an SpMV kernel benchmark for the three dimensional Laplacian 🦋

---

✨ SYNOPSIS ✨

spmvtest1 l m n iter [matrix_type]

okay so yes, the synopsis literally says spmvtest1 and not spmvtest3b. that's what the page says, and we're keeping it exactly as written, no cap. not me fixing things that aren't mine to fix 💅

---

✨ DESCRIPTION ✨

so what does this thing actually do? it computes the matrix-vector multiply of a discretized three dimensional Laplacian of size lmn, using the twenty-seven point central difference scheme, and a vector (1, ..., 1)^T. iconic honestly 🌸

the FLOPS performance gets measured as the average of iter iterations. she's an average girly, periodt.

if necessary, one of the following values can be specified by matrix_type:

• 0 — measure the performance for the available matrix storage formats ⭐
• 1-11 — the number of the matrix storage format

the values l, m and n represent the numbers of the grid points in each dimension. see the Lis User Guide for more information, iykyk 📖

---

✨ EXIT STATUS ✨

the following exit values are returned:

• 0 — the process is normally terminated 🎀
• unspecified — an error occurred 😭
