List of main options that can be used in timing:
* ~--help~: show usage
* ~--threads~: Number of CPU workers (default:
~_SC_NPROCESSORS_ONLN~)
* ~--gpus~: number of GPU workers (default: ~0~)
* ~--n_range=R~: range of N values, with ~R=Start:Stop:Step~
(default: ~500:5000:500~)
* ~--m=X~: dimension (M) of the matrices (default: ~N~)
* ~--k=X~: dimension (K) of the matrices (default: ~1~), useful for
GEMM algorithm (k is the shared dimension and must be defined
>1 to consider matrices and not vectors)
* ~--nrhs=X~: number of right-hand size (default: ~1~)
* ~--nb=X~: block/tile size. (default: ~128~)
* ~--ib=X~: inner-blocking/IB size. (default: ~32~)
* ~--niter=X~: number of iterations performed for each test
(default: ~1~)
* ~--rhblk=X~: if X > 0, enable Householder mode for QR and LQ
factorization. X is the size of each subdomain (default: ~0~)
* ~--[no]check~: check result (default: ~nocheck~)
* ~--[no]profile~: print profiling informations (default:
~noprofile~)
* ~--[no]trace~: enable/disable trace generation (default: ~notrace~)
* ~--[no]dag~: enable/disable DAG generation (default: ~nodag~)
* ~--[no]inv~: check on inverse (default: ~noinv~)
* ~--nocpu~: all GPU kernels are exclusively executed on GPUs
* ~--ooc~: Enable out-of-core (available only with StarPU)
* ~--bound~: Compare result to area bound (available only with
StarPU) (default: ~0~)
* ~--help~: Show usage
* Machine parameters
* ~-t x, --threads=x~: Number of CPU workers (default: automatic
detection through runtime)
* ~-g x, --gpus=x~: Number of GPU workers (default: ~0~)
* ~-P x, --P=x~: Rows (P) in the PxQ process grid (default: ~1~)
* ~--nocpu~: All GPU kernels are exclusively executed on GPUs
* Matrix parameters
* ~-m x, --m=X, --M=x~: Dimension (M) of the matrices (default:
~N~)
* ~-n x, --n=X, --N=x~: Dimension (N) of the matrices
* ~-N R, --n_range=R~: Range of N values to time with
~R=Start:Stop:Step~ (default: ~500:5000:500~)
* ~-k x, --k=x, --K=x, --nrhs=x~: Dimension (K) of the matrices
or number of right-hand size (default: ~1~). This is useful for
GEMM algorithms (k is the shared dimension and must be defined
>1 to consider matrices and not vectors)
* ~-b x, --nb=x~: NB size. (default: ~320~)
* ~-i x, --ib=x~: IB size. (default: ~32~)
* Check/prints
* ~--niter=X~: Number of iterations performed for each test
(default: ~1~)

* ~-c, --check~: Check result
* ~-C, --inc~: Check on inverse
* ~--mode=x~ : Change the xLATMS matrix mode generation for
SVD/EVD (default: ~4~). It must be between 0 and 20 included.
* Profiling parameters
* ~-T, --trace~: Enable trace generation
* ~--progress~: Display progress indicator
* ~-d, --dag~: Enable DAG generation. Generates a dot_dag_file.dot.
* ~-p, --profile~: Print profiling informations
* HQR parameters
* ~-a x, --qr_a=x, --rhblk=x~: Define the size of the local TS
trees in housholder reduction trees for QR and LQ
factorization. N is the size of each subdomain (default: ~-1~)
* ~-l x, --llvl=x~: Tree used for low level reduction inside
nodes (default: ~-1~)
* ~-L x, --hlvl=x~: Tree used for high level reduction between
nodes, only if P > 1 (default: ~-1~). Possible values are -1:
Automatic, 0: Flat, 1: Greedy, 2: Fibonacci, 3: Binary, 4:
Replicated greedy.
* ~-D, --domino~: Enable the domino between upper and lower trees
* Advanced options
* ~--nobigmat~: Disable single large matrix allocation for
multiple tiled allocations
* ~-s, --sync~: Enable synchronous calls in wrapper function such
as POTRI
