Geometry Configuration

PV3D is the format the viewer reads. Start from an example, or bring your own.

Already-converted traces on the server. Pick one to skip straight to the viewer.

Convert it locally with one of these, then choose the result below. Nothing leaves your machine.

Hybrid view with machine topology

Loads the trace and builds the geometry, so the ranks are on screen while you pick a metric in step 3 and watch the colouring follow.

Dual view

Include traditional (Vampir-like) view

Hide collectives

Hide point-to-point

Hiding is visual only — durations and percentiles still describe every call. Setup and query calls (MPI_Init, MPI_Comm_rank, MPI_Cart_…) belong to neither class and stay visible. To leave calls out of the statistics as well, re-convert with otf2_to_pv3d_v2.py --region-list … --region-list-mode ignore.

Re-renders with everything currently selected.
