💖 spmvtest3 — the SpMV girlies' three dimensional Laplacian benchmark 💖

okay so bestie, you know how this whole thing lives in the manual as spmvtest3(1)? yeah. that's her. that's the girl. she benchmarks the SpMV kernel for a three dimensional Laplacian and she does it flawlessly, no cap. 🎀

✨ NAME ✨

spmvtest3 — SpMV kernel benchmark of three dimensional Laplacian 🦋

---

🌸 SYNOPSIS 🌸

spmvtest1 l m n iter [matrix_type]

not me clocking that the synopsis literally says spmvtest1 and not spmvtest3... i'm just the messenger bestie, i am NOT touching it, that's exactly what the page says 💅

👑 DESCRIPTION 👑

so basically this program computes the matrix-vector multiply of a discretized three dimensional Laplacian of size lmn, using the seven point central difference scheme, and a vector (1, ..., 1)^T. iconic behavior honestly. ⭐

the FLOPS performance gets measured as the average of iter iterations. literally just vibes and flops.

and if necessary, one of these 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 Lis User Guide for more information, because she has receipts. 📖

💀 EXIT STATUS 💀

the following exit values are returned:

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