Resource scheduling plays a vital role in High-Performance Computing (HPC) systems. However, most scheduling research in HPC has focused on only a single type of resource (e.g., computing cores or I/O resources). With the advancement in hardware architectures and the increase in data-intensive HPC applications, there is a need to simultaneously embrace a diverse set of resources (e.g., computing cores, cache, memory, I/O, and network resources) in the design of runtime schedulers for improving the overall application performance. This thesis performs an empirical evaluation of a recently proposed multi-resource scheduling algorithm for minimizing the overall completion time (or makespan) of computational workflows comprised of moldable parallel jobs. Moldable parallel jobs allow the scheduler to select the resource allocations at launch time and thus can adapt to the available system resources (as compared to rigid jobs) while staying easy to design and implement (as compared to malleable jobs). The algorithm was proven to have a worst-case approximation ratio that grows linearly with the number of resource types for moldable workflows. In this thesis, a comprehensive set of simulations is conducted to empirically evaluate the performance of the algorithm using synthetic workflows generated by DAGGEN and moldable jobs that exhibit different speedup profiles. The results show that the algorithm fares better than the theoretical bound predicts, and it consistently outperforms two baseline heuristics under a variety of parameter settings, illustrating its robust practical performance.

As the world recovers from the damage caused by the spread of COVID-19, the monkeypox virus poses a new threat of becoming a global pandemic. The monkeypox virus itself is not as deadly or contagious as COVID-19, but many countries report new patient cases every day. So it wouldn't be surprising if the world faces another pandemic due to lack of proper precautions. Recently, deep learning has shown great potential in image-based diagnostics, such as cancer detection, tumor cell identification, and COVID-19 patient detection. Therefore, since monkeypox has infected human skin, a similar application can be employed in diagnosing monkeypox-related diseases, and this image can be captured and used for further disease diagnosis. This project presents a deep learning approach for detecting monkeypox disease from skin lesion images. Several pre-trained deep learning models, such as ResNet50 and Mobilenet, are deployed on the dataset to classify monkeypox and other diseases.
