The GetLastResult command gets the last result computed on the specified grid node.

The last result could be any activity initiated by the Launch , Run , Set , or Get commands.

This command can only be used when a node is finished computing. If the specified node is not yet done computing, GetLastResult will block and wait for the computation to finish.

The GetLastResult command is only available in local Grid mode.

$\mathrm{Grid}:-\mathrm{Run}\left(0\,\mathrm{int}\,\left[x\,x\right]\right)$

$\mathrm{Grid}:-\mathrm{Run}\left(1\,\mathrm{int}\,\left['\sin \left(x\right)'\,x\right]\right)$

$\mathrm{Grid}:-\mathrm{GetLastResult}\left(1\right)$

$-\cos \left(x\right)$

$\mathrm{Grid}:-\mathrm{GetLastResult}\left(0\right)$

$\frac{x^2}{2}$

$\mathrm{Grid}:-\mathrm{Run}\left(1\,\mathrm{print}\,\left[42\right]\right)$

$r≔\mathrm{Grid}:-\mathrm{GetLastResult}\left(1\right)$

$\mathrm{evalb}\left(r=\mathrm{NULL}\right)$
