    <p>This is probably too late but if you write a signal-handler function you can get rid of the memory leaks and reset the device in a sure way:</p> <pre><code>// State variables for extern int no_sigint; int no_sigint = 1; extern int interrupts; int interrupts = 0; /* Catches signal interrupts from Ctrl+c. If 1 signal is detected the simulation finishes the current frame and exits in a clean state. If Ctrl+c is pressed again it terminates the application without completing writes to files or calculations but deallocates all memory anyway. */ void sigint_handler (int sig) { if (sig == SIGINT) { interrupts += 1; std::cout &lt;&lt; std::endl &lt;&lt; "Aborting loop.. finishing frame." &lt;&lt; std::endl; no_sigint = 0; if (interrupts &gt;= 2) { std::cerr &lt;&lt; std::endl &lt;&lt; "Multiple Interrupts issued: " &lt;&lt; "Clearing memory and Forcing immediate shutdown!" &lt;&lt; std::endl; // write a function to free dynamycally allocated memory free_mem (); int devCount; cudaGetDeviceCount (&amp;devCount); for (int i = 0; i &lt; devCount; ++i) { cudaSetDevice (i); cudaDeviceReset (); } exit (9); } } } </code></pre> <p>....</p> <pre><code>int main(){ ..... for (int simulation_step=1 ; simulation_step &lt; SIM_STEPS &amp;&amp; no_sigint; ++simulation_step) { .... simulation code } free_mem(); ... cuda device resets return 0; } </code></pre> <p>If you use this code (you can even include the first snippet in an external header, it works. You can have 2 levels of control of ctrl+c: the first press stops your simulation and exits normally but the application finishes rendering the step which is great to stop gracefully and have correct results, if you press ctrl+c again it closes the application freeing all memory.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
