 ## Reference timings
 
-These benchmarks were run during the pilot phase of the LUMI-G supercomputer (December 2022), under
-git commit d8f36242127b9a828f127550ecd9613eefb3f1cc. All calculations were run with 8 GPUs, 16 MPI
-ranks, and 3 OMP threads per node. Note that this amounts to a total of 48 out of the 64 CPUs of a
-LUMI-G node, because full nodes where not available at the time.

 ## Notes on parameter choice and performance
 
@@ -55,11 +57,11 @@ Most input files use 4 as the value for MEMORY_CUT. This controls the batching p
 tensor contractions such that the memory footprint remains limited. Note that using a high value for
 this keyword leads to overheads. As an illustration, the H2O-128-RPA-TZ.inp input file with MEMORY_CUT
 set to 3 does not run on 32 LUMI-G nodes because of memory. However, it runs on 64 nodes with a wall
-time of 2149.162 seconds (compared to 2577.737 seconds with MEMORY_CUT set to 4).
+time of 2149 seconds (compared to 2578 seconds with MEMORY_CUT set to 4).
 
 Finally, the value of 6 was chosen for the MIN_BLOCK_SIZE keyword, while the default is 5. This is
 a trade-off between better sparsity for smaller block size, and higher efficiency of block-wise
 matrix-matrix mulitplications for larger sizes. This mostly matters for the force calculations of large
 system, because the bottleneck of the calculation involves the contraction of fairly dense tensors.
