sponsored by the Apache Incubator PMC. Incubation is required of all newly 
accepted projects until a further review indicates that the infrastructure, 
communications, and decision making process have stabilized in a manner 
consistent with other successful ASF projects. While incubation status is not 
necessarily a reflection of the completeness or stability of the code, it does 
indicate that the project has yet to be fully endorsed by the ASF.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+<p>
+In this blog we explore the sorting performance of Spark/Crail on a 100Gbit/s 
RDMA cluster. Sorting large data sets efficiently on a cluster is particularly 
interesting from a network perspective as most of the input data will have to 
cross the network at least once. Hence, a sorting workload should be an ideal 
candidate to be accelerated by a fast network. 
+</p>
+<p>
+The following table summarizes the results of this blog and provides a 
comparison with other sorting benchmarks. In essence, Spark/Crail is sorting 
12.8 TB of data in 98 seconds, which calculates to a sorting rate of 3.13 
GB/min/core. This is about a factor of 5 faster than the sorting performance of 
the <a 
href="https://databricks.com/blog/2014/11/05/spark-officially-sets-a-new-record-in-large-scale-sorting.html";>Spark
 2014 benchmark winner</a>, and only about 28% slower than the <a 
href="http://sortbenchmark.org/TencentSort2016.pdf";>2016 winner of the sorting 
benchmark</a> -- a sorting benchmark running native code optimized specifically 
for sorting.

+<p>
+A Spark sorting job  consists of two phases. The first phase is a mapping or 
classification phase - where individual workers read their part of the 
key-value (KV) input data and classify the KV pairs based on their keys. This 
phase involves only very little networking as most of the workers run locally 
on the nodes that host the HDFS data blocks. During the second so called reduce 
phase, each worker collects all KV pairs for a particular key range from all 
the workers, de-serializes the data and sorts the resulting objects. This 
pipeline runs on all cores in multiple waves of tasks on all the compute nodes 
in the cluster. Naturally, the performance of such a pipeline depends upon both 
the network as well as the CPU performance, which together should dictate the 
overall job run time.

+
+<h3 id="using-vanilla-spark">Using Vanilla Spark</h3>
+
+<div style="text-align: justify"> 
+<p>
+The first question we are interested in is to what extent such a sorting 
benchmark can drive the 100Gbit/s network fabric. Making good use of the 
network is important since a reduce task needs to first fetch all the relevant 
data from the network before it can start sorting the data. Unfortunately, it 
turns out that when running vanilla Spark on the cluster, the network usage 
stays at only 5-10%. 
+</p>
+</div>
+
+<p><br /></p>
+<div style="text-align:center"><img 
src="http://crail.incubator.apache.org/img/blog/sort/net_vanilla.svg"; /></div>
+<p><br /><br /></p>
+
+<div style="text-align: justify"> 
+<p>
+The poor network usage matches with the general observation we made in our 
previous <a href="http://dl.acm.org/citation.cfm?id=3027062";>HotCloud'16 
publication</a> where we show that a faster network does not necessarily lead 
to a better runtime. The problem can be understood by looking at a single 
reduce task in the sorting benchmark. While the actual time for fetching all 
the data over the network decreases with increasing network bandwidth, the time 
a reduce task spends on funneling the data through the stack, deserializing and 
sorting it outweighs the transmission time by far. The figure below shows 
percentage wise for different network technologies, how much time a reduce task 
spends on waiting for data versus executing CPU instructions (a more detailed 
breakdown of the time can be found in the <a 
href="http://dl.acm.org/citation.cfm?id=3027062";>paper</a>). Clearly, in such a 
situation, a higher network bandwidth will only improve the increasinlgy small 
red part and, and thus, 
 will not result in a substantial runtime reduction.

+
+<div style="text-align: justify"> 
+<p>
+Consequently, to improve the runtime of the sorting benchmark and to make good 
use of the 100Gbit/s network, the number of CPU instructions executed per byte 
transferred need to be reduced massively. In the following, we show how we use 
the Crail shuffle engine to cut down the software overheads related to 
networking, deserialization and sorting and thereby empower the reduce tasks in 
the sorting benchmark to consume data at a speed that is very close to the 
network limit (~70Gbit/s all-to-all).

+<h3 id="using-the-crail-shuffler">Using the Crail Shuffler</h3>
+
+<div style="text-align: justify"> 
+<p>
+An overview of the Crail shuffler is provided in the <a 
href="http://crail.incubator.apache.org/docs";>documentation section</a>. The 
main difference between the Crail shuffler and the Spark built-in shuffler lies 
in the way data from the network is processed in a reduce task. The Spark 
shuffler is based on TCP sockets, thus, many CPU instructions are necessary to 
bring the data from the networking interface to the buffer inside Spark. In 
contrast, the Crail shuffler shares shuffle data through the Crail file system, 
and therefore data is transferred directly via DMA from the network interface 
to the Spark shuffle buffer within the JVM. 
+</p>
+</div>
+
+<p><br /></p>
+<div style="text-align:center"><img 
src="http://crail.incubator.apache.org/img/blog/sort/shuffle_rdma.png"; 
width="470" /></div>
+<p><br /><br /></p>
+
+<div style="text-align: justify"> 
+<p>
+During the map phase, the Crail shuffler organizes each key range in a set of 
Crail files, one file per Spark core per key range. Reading the shuffle data 
from the Crail file system in the reduce phase not only eliminates data copies 
and avoids system calls, it also makes sure the different segments (files) are 
placed at the right offset within the reduce buffer to create one contiguous 
memory area that can immediately be used for deserialization and sorting.  
+</p>
+
+<p>
+As illustrated in the <a 
href="http://crail.incubator.apache.org/docs";>documentation section</a>, the 
Crail shuffler allows applications to use their own custom serializer and 
sorter. The recommended serializer for Spark is Kryo, which is a generic 
serializer. Being generic, however, comes at a cost. Specifically, Kryo 
requires more type information to be stored along with the serialized data than 
a custom serializer would need, and also the parsing is more complex for a 
generic serializer. On top of this, Kryo also comes with its own buffering, 
introducing additional memory copies. In our benchmark, we use a custom 
serializer that takes advantage of the fact that the data consists of fixed 
size key/value pairs. The custom serializer further avoids extra buffering and 
directly interfaces with Crail file system streams when reading and writing 
data. 
+</p>
+<p>
+As with serialization, the Spark built-in sorter is a general purpose TimSort 
that can sort arbitrary collections of comparable objects. In our benchmark, we 
instruct the Crail shuffler to use a Radix sorter instead. The Radix sorter 
cannot be applied to arbitrary objects but works well for keys of a fixed byte 
length. The standard pipeline of a reduce task is to first deserialize the data 
and then sort it. In the particular configuration of the Crail shuffler, we 
turn these two steps around and first sort the data and deserialize it later. 
This is possible because the data is read into a contiguous off-heap buffer 
that can be sorted almost in-place. 
+</p>
+</div>
+
+<h3 id="sparkcrail-sorting-performance">Spark/Crail Sorting Performance</h3>
+
+<div style="text-align: justify"> 
+<p>
+The figure below shows the overall performance of Spark/Crail vs Spark/Vanilla 
on a 12.8 TB data set. With a cluster size of 128 nodes, each node gets to sort 
100GB of data - if the data distribution is uniform. As can be seen, using the 
Crail shuffler, the total job runtime is reduced by a factor of 6. Most of the 
gains come from the reduce side, which is where the networking takes place. 
However, the map phase is also faster which comes from the more efficient 
serialization but also from a faster I/O. The built-in Spark shuffler dumps 
data into files absorbed by the buffer cache (no disk writes took place during 
shuffle), which requires file system calls and data copies. The Crail shuffler 
instead uses memory mapped I/O to write local Crail files, avoiding both data 
copies, system calls and kernel context switches.

+
+<p>One key question of interest is about the network usage of the Crail 
shuffler during the sorting benchmark. In the figure below, we show the data 
rate at which the different reduce tasks fetch data from the network. Each 
point in the figure corresponds to one reduce task. In our configuration, we 
run 3 Spark executors per node and 5 Spark cores per executor. Thus, 1920 
reduce tasks are running concurrently (out of 6400 reduce tasks in total) 
generating a cluster-wide all-to-all traffic of about 70Gbit/s per node during 
that phase.</p>

+<p><br /><br /></p>
+
+<p>In this blog post, we have shown that Crail successfully manages to 
translate the raw network performance into actual workload level gains. The 
exercise with TeraSort as an application validates the design decisions we made 
in Crail. Stay tuned for more results with different workloads and hardware 
configurations.</p>

+<h3 id="how-to-run-sorting-with-sparkcrail">How to run Sorting with 
Spark/Crail</h3>
+
+<p>All the components required to run the sorting benchmark using Spark/Crail 
are open source. Here is some guidance how to run the benchmark:</p>
+
+<ul>
+  <li>Build and deploy Crail using the instructions at <a 
href="http://crail.incubator.apache.org/documentation#crail";>documentation</a></li>
+  <li>Enable the Crail shuffler for Spark by building Spark-IO using the 
instructions at <a 
href="http://crail.incubator.apache.org/documentation#spark";>documentation</a></li>
+  <li>Configure the DRAM storage tier of Crail so that all the shuffle data 
fits into the DRAM tier.</li>
+  <li>Build the sorting benchmark using the instructions on <a 
href="https://github.com/zrlio/crail-terasort";>GitHub</a></li>
+  <li>Make sure you have the custom serializer and sorter specified in 
spark-defaults.conf</li>
+  <li>Run Hadoop TeraGen to produce a valid data set. We used standard HDFS 
for both input and output data.</li>
+  <li>Run the Crail-TeraSort on your Spark cluster. The command line we have 
used on the 128 node cluster is the following:</li>
+</ul>
