<p>Dear Flash users,</p>
<p><br>
</p>
<p>I am experiencing a memory leak when trying to use the cray-compiler environment. The memory monitor</p>
<p>reports an increase in the max rss and vsize memory. The increasing trend is more or less linear, but shows some variation</p>
<p>with problem and processor. The issue does not persist when using gnu compilers. I think the issue is related to internode communication,</p>
<p>but I have not been able to track it down.<br>
</p>
<p><br>
</p>
<p>What I have found so far:</p>
<p>- Occurs in both 2D and 3D</p>
<p>- Occurs in the Sedov and Sod test problems.</p>
<p>- Not every process leaks, but there is no clear pattern either.</p>
<p>- Number of leaking processes is often small compared to the total number of processes</p>
<p>- Occurs for both UG and Paramesh and Uniform Grid.</p>
<p>- Does not occur when running on a single node.</p>
<p>- Seems to happen during guard-cell fills</p>
<p><br>
</p>
<p>I found a report in the mailing list archive of a similar issue, but it was related to HYPRE, which
<br>
</p>
<p>I do not use.</p>
<p><br>
</p>
<p>Any input/ideas would be appreciated. <br>
</p>
<p><br>
</p>
<p>Best,<br>
Haakon<br>
