- svPerfGL
- Description:
svPerfGL is an OpenGL benchmark intended to measure "real world"
performance of scientific visualization applications. These applications
are characterized by relatively high payload (i.e., lots of triangles)
with relatively few OpenGL state changes. This application takes as input
disjoint triangle payload contained in files in netCDF format, renders
the frames over a user-specified time duration, rotates the entire scene
by one degree per frame, then computes and reports a "triangles per second"
performance metric upon exit.

https://codeforge.lbl.gov/projects/svperfgl/. Note: at the present time, there is no sample
data needed for svPerfGL runs available for download from
codeforge.lbl.gov due to restrictions on the size of files we can
upload to that webserver – the data files are quite large
(10MB for the smallest up to about 32GB for the largest). Contact us
if you need access to the data, we'll work something out. We expect
this restriction to eventually be removed with upgrades to codeforge.lbl.gov.
- mpiReadWriteTest
- Description: mpiReadWriteTest is an MPI-based
application that can be used to measure the parallel I/O performance
of a computational platform. While it is not as efficient as a low-level
utility that reads/writes disk blocks, it is representative of
the type of performance one could reasonably expect from a "garden
variety parallel application." We have used this benchmark extensively
on our parallel systems to characterize I/O performance and as part
of filesystem tuning.
