System and method for increasing robustness of heterogeneous computing systems
Disclosed is a method for task pruning that can be utilized in existing resource allocation systems to improve the systems' robustness without requiring changing to existing mapping heuristics.

Pruning tasks whose chance of success is low improves the chance of success for other tasks. Tasks that are unlikely to succeed are either deferred from current scheduling event or are preemptively dropped from the system. The pruning method can benefit service providers by allowing them to utilize their resources more efficiently and use them only for tasks that can meet their deadlines. The pruning method further helps end users by making the system more robust in allowing more tasks to complete on time. |

Heterologous biosynthesis of nodulisporic acid
Nodulisporic acids (NAs) comprise a group of indole diterpenes known for their potent insecticidal activities; however, biosynthesis of NAs by its natural producer, Hypoxylon pulicicidum (Nodulisporium sp.) is exceptionally difficult to achieve. The identification of genes responsible for NA production could enable biosynthetic pathway optimization to provide access to NAs for commercial applications. Obtaining useful quantities of NAs using published fermentations methods is challenging, making gene knockout studies an undesirable method to confirm gene function. Alternatively, heterologous gene expression of H. pulicicidum genes in a more robust host species like Penicillium paxilli provides a way to rapidly identify the function of genes that play a role in NA biosynthesis. In this work, we identified the function of four secondary-metabolic genes necessary for the biosynthesis of nodulisporic acid F (NAF) and reconstituted these genes in the genome of P. paxilli to enable heterologous production of NAF in this fungus. |
