Purpose:
[is this a bug fix? feature? ...]
Description:
[describe the bug, or describe the new feature, etc]
Solution:
[details about the changes, algorithm, etc...]
[Please as detail as you can since your own explanation is
better than others guessing it from the code.]
Platforms tested:
[machines you have tested the changed version. This is absolute
important. Test it out on at least two or three different platforms
such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]

<h3>Section 2: HDF File Organization</h3>
|
|
|
|
<ol>
|
|
<li>Name and describe the two primary objects that can be stored in an HDF5
|
|
file.
|
|
|
|
<p>
|
|
<li>What is an attribute?
|
|
|
|
<p>
|
|
<li>Give the path name for an object called <code>harry</code> that is a member of a
|
|
group called <code>dick</code>, which, in turn, is a member of the root group.
|
|
</ol>
|
|
|
|
|
|
<h3>Section 3: The HDF5 API</h3>
|
|
|
|
<ol>
|
|
<li>Describe the purpose of each of the following HDF5 APIs:
|
|
<dir>
|
|
H5A, H5D, H5E, H5F, H5G, H5T, H5Z
|
|
</dir>
|
|
</ol>
|
|
|
|
|
|
<h3>Section 4: Creating an HDF5 File</h3>
|
|
|
|
<ol>
|
|
<li>What two HDF5 routines must be called to create an HDF5 file?
|
|
|
|
<p>
|
|
<li>What include file must be included in any file that uses the HDF5 library?
|
|
|
|
<p>
|
|
<li>An HDF5 file is never completely empty because as soon as it is created,
|
|
it automatically contains a certain primary object. What is that object?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 5: Creating a Dataset</h3>
|
|
|
|
<ol>
|
|
<li>Name and describe two major datatype categories.
|
|
|
|
<p>
|
|
<li>List the HDF5 atomic datatypes. Give an example of a predefined datatype.
|
|
|
|
<p>
|
|
<li>What does the dataspace describe? What are the major characteristics of
|
|
the simple dataspace?
|
|
|
|
<p>
|
|
<li>What information needs to be passed to the <code>H5Dcreate</code>
|
|
function, i.e., what information is needed to describe a dataset at
|
|
creation time?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 6: Reading from and Writing to a Dataset</h3>
|
|
|
|
<ol>
|
|
<li>What are six pieces of information which need to be specified for
|
|
reading and writing a dataset?
|
|
|
|
<p>
|
|
<li>Why are both the memory dataspace and file dataspace needed for
|
|
read/write operations, while only the memory datatype is required?
|
|
|
|
<p>
|
|
<li>What does the line
|
|
<br>
|
|
<code>DATASPACE { SIMPLE (4 , 6 ) / ( 4 , 6 ) } </code>
|
|
<br>in Figure 6.1 mean?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 7: Creating an Attribute</h3>
|
|
|
|
<ol>
|
|
<li>What is an attribute?
|
|
|
|
<p>
|
|
<li>Can partial I/O operations be performed on attributes?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 8: Creating a Group</h3>
|
|
|
|
<ol>
|
|
<li>What are the two primary objects that can be included in a group?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 9: Creating Groups Using Absolute and Relative Names</h3>
|
|
|
|
<ol>
|
|
<li>Group names can be specified in two ways. What are these two types
|
|
of group names?
|
|
|
|
<p>
|
|
<li>You have a dataset named <code>moo</code> in the group <code>boo</code>, which is
|
|
in the group <code>foo</code>, which, in turn, is in the root group.
|
|
How would you specify an absolute name to access this dataset?
|
|
</ol>
|
|
|
|
|
|
<h3>Section 10: Creating Datasets in Groups</h3>
|
|
|
|
<ol>
|
|
<li>Describe a way to access the dataset <code>moo</code> described in the
|
|
previous section (Section 9, question 2) using a relative name.
|
|
Describe a way to access the same dataset using an absolute name.
|
|
</ol>
