Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

Title: Multiprocessing Systems and Deadlock Handling Strategies
Abstract
This report aims to explore multiprocessing systems and deadlock handling strategies. It begins by differentiating the common configurations of multiprocessing systems. It then delves into the conditions necessary for a deadlock to occur and discusses the option to remove one condition to prevent deadlock. Furthermore, it explains various deadlock handling strategies and provides suitable strategies for removing deadlocks in the cases of disk sharing, database sharing, and multiple device allocation. The chosen strategies are supported by appropriate justifications.

Introduction
Multiprocessing systems play a vital role in enhancing computer performance by allowing multiple tasks to be executed simultaneously. However, these systems can also face challenges, such as deadlocks, which hinder their efficiency. Deadlock is a state in which two or more processes are unable to proceed because each is waiting for the other to release a resource. This report aims to shed light on the different configurations of multiprocessing systems, the conditions necessary for a deadlock to occur, and various deadlock handling strategies.

Differentiating Common Configurations of Multiprocessing Systems
Symmetric Multiprocessing (SMP): In SMP, all processors have equal access to the system’s memory and I/O devices. Processes can be executed on any available processor, providing load balancing and increased system throughput.
Asymmetric Multiprocessing (AMP): AMP involves a master-slave relationship among processors. One processor, known as the master, controls the system’s resources and schedules tasks for execution on the slave processors.
Clustered Multiprocessing: In clustered multiprocessing, multiple individual systems are interconnected to form a cluster. Each system operates independently but can communicate and share resources with other systems in the cluster.
Conditions Necessary for a Deadlock to Occur
A deadlock can occur when four necessary conditions are present simultaneously:

Mutual Exclusion: Resources involved in the deadlock must be non-shareable, meaning only one process can access them at a time.
Hold and Wait: Processes hold resources while waiting for additional resources, resulting in resource wastage and potential deadlock situations.
No Preemption: Resources cannot be forcibly taken away from a process without its cooperation.
Circular Wait: A circular chain of processes exists, where each process holds a resource that is requested by the next process in the chain.
If given the option of removing one condition to prevent deadlock, the condition of “Circular Wait” would be the most suitable choice. By breaking the circular chain of processes, it becomes impossible for a deadlock to occur.

Different Deadlock Handling Strategies
Deadlock Prevention: This strategy focuses on preventing any of the four necessary conditions for a deadlock from occurring. It involves careful resource allocation, ensuring that at least one of the necessary conditions is not satisfied.
Deadlock Avoidance: This strategy utilizes algorithms and heuristics to predict whether a particular resource allocation might lead to a deadlock. If a potential deadlock is detected, the system denies or delays resource allocation until deadlock risk is eliminated.
Deadlock Detection and Recovery: This strategy periodically checks the system for deadlocks using algorithms like resource allocation graphs or bankers’ algorithm. If a deadlock is detected, appropriate recovery actions are taken, such as terminating some processes or rolling back their progress.
Deadlock Ignorance: In some cases, ignoring deadlocks might be a viable strategy if the occurrence of deadlocks is extremely rare or their impact is minimal.
Suitable Deadlock Handling Strategies for Specific Cases
Disk Sharing: In the case of disk sharing, where multiple processes need access to shared storage, a suitable strategy would be Deadlock Prevention. By carefully managing resource allocation and ensuring that processes do not hold resources indefinitely, the occurrence of deadlocks can be prevented.
Database Sharing: For scenarios involving database sharing among multiple processes, Deadlock Detection and Recovery would be an appropriate strategy. Databases often involve complex interactions among multiple transactions, making it difficult to predict potential deadlocks. Regularly detecting and recovering from deadlocks ensures uninterrupted database access.
Multiple Device Allocation: When dealing with multiple device allocation, where processes require access to various devices simultaneously, a suitable strategy would be Deadlock Avoidance. By utilizing algorithms that predict potential deadlocks based on resource requests and releases, the system can avoid allocating resources that could lead to deadlocks.

Conclusion
Understanding the different configurations of multiprocessing systems and the conditions necessary for deadlocks is crucial for maintaining system efficiency. By removing the condition of “Circular Wait,” deadlocks can be effectively prevented. Employing suitable deadlock handling strategies such as prevention, avoidance, detection and recovery, or ignorance based on specific scenarios ensures optimal system performance and resource utilization. Disk sharing benefits from prevention, database sharing requires detection and recovery, while multiple device allocation benefits from avoidance strategies. By implementing these strategies with careful consideration, deadlocks can be mitigated and system reliability improved.
