<h3>Features</h3>
Nathalie Furmento's avatar

161
<h4>Portability</h4>
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
162
  <p>
163 164 165 166 167 168 169 170
Portability is obtained by the means of a unified abstraction of the machine.
StarPU offers a unified offloadable task abstraction named <em>codelet</em>. Rather
than rewriting the entire code, programmers can encapsulate existing functions
within codelets. In case a codelet can run on heterogeneous architectures, <b>it
is possible to specify one function for each architectures</b> (e.g. one function
for CUDA and one function for CPUs). StarPU takes care of scheduling and
executing those codelets as efficiently as possible over the entire machine, include
multiple GPUs.
171 172 173 174
One can even specify <b>several functions for each architecture</b> (new in
v1.0) as well as
<b>parallel implementations</b> (e.g. in OpenMP), and StarPU will
automatically determine which version is best for each input size (new in v0.9).
175 176 177
StarPU can execute them concurrently, e.g. one per socket, provided that the
task implementations support it (which is the case for MKL, but unfortunately
most often not for OpenMP).

  </p>

180 181 182
<h4>Genericity</h4>
  <p>
The StarPU programming interface is very generic. For intance, various data
183
structures are supported mainline (vectors, dense matrices, CSR/BCSR/COO sparse matrices, ...),
184 185 186 187 188 189
but application-specific data structures can also be supported, provided that
the application describes how data is to be transfered (e.g. a series of
contiguous blocks). That was for instance used for hierarchically-compressed
matrices (h-matrices).
  </p>

190
<h4>Data transfers</h4>
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
191
  <p>
192
To relieve programmers from the burden of explicit data transfers, a high-level
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
193
data management library enforces memory coherency over the machine: before a
194 195
codelet starts (e.g. on an accelerator), all its <b>data are automatically made
available on the compute resource</b>. Data are also kept on e.g. GPUs as long as
THIBAULT Samuel's avatar
THIBAULT Samuel committed
196 197
they are needed for further tasks. When a device runs out of memory, StarPU uses
an LRU strategy to <b>evict unused data</b>. StarPU also takes care of <b>automatically
198
prefetching</b> data, which thus permits to <b>overlap data transfers with computations</b>
THIBAULT Samuel's avatar
update  
THIBAULT Samuel committed
199
(including <b>GPU-GPU direct transfers</b>) to achieve the most of the architecture.

202
<h4>Dependencies</h4>
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
203
  <p>
204
Dependencies between tasks can be given either of several ways, to provide the
205 206
programmer with best flexibility:
  <ul>
207
    <li><b>implicitly</b> from RAW, WAW, and WAR data dependencies.</li>
THIBAULT Samuel's avatar
THIBAULT Samuel committed
208
    <li>explicitly through <b>tags</b> which act as rendez-vous points between
209
    tasks (thus including tasks which have not been created yet),</li>
210
    <li><b>explicitly</b> between pairs of tasks,</li>
211
  </ul>
212 213
  </p>
  <p>
214 215 216
  These dependencies are computed in a completely decentralized way, and can be
  introduced completely dynamically as tasks get submitted by the application
  while tasks previously submitted are being executed.
217 218
  </p>
  <p>
219 220 221 222
StarPU also supports an OpenMP-like <a href="doc/html/DataManagement.html#DataReduction">reduction</a> access mode (new in v0.9).
  </p>
  <p>
It also supports a <a href="doc/html/DataManagement.html#DataCommute">commute</a> access mode to allow data access commutativity (new in v1.2).
223 224
  </p>

225 226 227 228 229
  <p>
It also supports transparent dependencies tracking between hierarchical subpieces of data
through asynchronous partitioning (new in v1.3).
  </p>

230 231 232
<h4>Heterogeneous Scheduling</h4>
  <p>
StarPU obtains
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
233
portable performances by efficiently (and easily) using all computing resources
234
at the same time. StarPU also takes advantage of the <b>heterogeneous</b> nature of a
Nathalie Furmento's avatar
website  
Nathalie Furmento committed
235
machine, for instance by using scheduling strategies based on auto-tuned
236 237 238
performance models. These determine the relative performance achieved
by the different processing units for the various kinds of task, and thus
permits to <b>automatically let processing units execute the tasks they are the best for</b>.
239
Various strategies and variants are available. Some of them are centralized, but
240
most of them are <b>completely distributed</b>. <i>dmdas</i> (a data-locality-aware MCT strategy,
241
thus similar to heft but starts executing tasks before the whole task graph is
242 243 244
submitted, thus allowing dynamic task submission and a decentralized scheduler,
as well as an energy optimizing extension), <i>eager</i> (dumb centralized
queue), <i>lws</i> (decentralized locality-aware work-stealing), ...
245
The overhead per task is typically around the order of
246 247 248
magnitude of a microsecond. Tasks should thus be a few orders of magnitude
bigger, such as 100 microseconds or 1 millisecond, to make the overhead
negligible.

251 252
<h4>Clusters</h4>
  <p>
253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274
To deal with clusters, StarPU can nicely integrate with <a
	href="doc/html/MPISupport.html">MPI</a>, through explicit or implicit
support, according to the application's preference.

    <ul>
        <li>Explicit network communication requests can be emitted, which will
then be <b>automatically combined and overlapped</b> with the intra-node data
transfers and computation,
        <li>The application can also just provide the whole task graph, a
data distribution over MPI nodes, and StarPU will automatically determine which
MPI node should execute which task, and <b>automatically generate all required
MPI communications</b> accordingly (new in v0.9). We have gotten excellent
scaling on a 256-node cluster with GPUs, we have not yet had the opportunity
to test on a yet larger cluster. We have however measured that with naive task
submission, it should scale to a thousand nodes, and with pruning-tuned task
submission, it should scale to about a <b>million nodes</b>.
        <li>Starting with v1.3, the application can also just provide the
whole task graph, and let StarPU decide the data distribution and task
distribution, thanks to a master-slave mechanism. This will however by nature
have a more limited scalability than the fully distributed paradigm mentioned
above.
    </ul>
275 276 277 278 279
  </p>

<h4>Out of core</h4>
  <p>
When memory is not big enough for the working set, one may have to resort to
Nathalie Furmento's avatar
Nathalie Furmento committed
280
using disks. StarPU makes this seamless thanks to its <a href="doc/html/OutOfCore.html">out of core support</a> (new in v1.2).
THIBAULT Samuel's avatar
update  
THIBAULT Samuel committed
281 282
StarPU will <b>automatically evict</b> data from the main memory in advance, and
<b>prefetch back</b> required data before it is needed for tasks.
283 284
  </p>

286 287 288
<h4>Extensions to the C Language</h4>
<p>
  StarPU comes with a GCC plug-in
289
  that <a href="doc/html/cExtensions.html">extends the C programming
290 291
  language</a> with pragmas and attributes that make it easy
  to <b>annotate a sequential C program to turn it into a parallel

303
  <a href=http://kstar.gforge.inria.fr/>K'Star</a> provides an OpenMP
THIBAULT Samuel's avatar
THIBAULT Samuel committed
304 305 306 307 308 309 310 311 312
  4 -compatible interface on top of StarPU. This allows to just rebuild OpenMP
  applications with the K'Star source-to-source compiler, then build it with the
  usual compiler, and the result will use the StarPU runtime.
</p>
<p>
  K'Star also provides some extensions to the OpenMP 4 standard, to let the
  StarPU runtime perform online optimizations.
</p>

313 314 315 316
<h4>OpenCL-compatible interface</h4>
<p>
  StarPU provides an <a href="doc/html/SOCLOpenclExtensions.html">OpenCL-compatible interface, SOCL</a>
  which allows to simply run OpenCL applications on top of StarPU (new in v1.0).
317 318
</p>

319 320 321 322
<h4>Simulation support</h4>
<p>
  StarPU can very accurately simulate an application execution
  and measure the resulting performance thanks to using the
323
  <a href="http://simgrid.gforge.inria.fr">SimGrid simulator</a> (new in v1.1).  This allows
324 325 326 327 328
  to quickly experiment with various scheduling heuristics, various application
  algorithms, and even various platforms (available GPUs and CPUs, available
  bandwidth)!
</p>

329 330
<h4>All in all</h4>
  <p>
331 332 333
All that means that the following sequential source code of a tiled version of
the classical Cholesky factorization algorithm using BLAS is also (a
almost) valid StarPU code, possibly running on all the CPUs and GPUs, and given a data

In order to understand the performance obtained by StarPU, it is helpful to
visualize the actual behaviour of the applications running on complex
heterogeneous multicore architectures.  StarPU therefore makes it possible to
generate Pajé traces that can be visualized thanks to the <a

<b>Example:</b> LU decomposition on 3 CPU cores and a GPU using a very simple
greedy scheduling strategy. The green (resp. red) sections indicate when the
corresponding processing unit is busy (resp. idle). The number of ready tasks

This second trace depicts the behaviour of the same application using a
scheduling strategy trying to minimize load imbalance thanks to auto-tuned
performance models and to keep data locality as high as possible. In this
example, the Pajé trace clearly shows that this scheduling strategy outperforms
the previous one in terms of processor usage. <b>Measured speed: 239.60

<p>Note that the dmdas scheduler uses performance models, and thus needs
calibration execution before exhibiting optimized performance (until the "model
something is not calibrated enough" messages go away).</p>

Starting with StarPU 1.1, it is also possible to reproduce the performance that
we show in our articles on our machines, by installing simgrid, and then using
the simulation mode of StarPU using the performance models of our machines:
