Title: Optimization of the use of memory on Devnet with increased rust calculation limits
Entry
Solana is a fast and scalable blockchain platform, but its high computing requirements can lead to memory restrictions. When building application for salt, it is necessary to effectively manage memory to ensure efficient efficiency and scalability. In this article, we will examine how to increase the calculation limit for Solana Devnet with Rust.
Understanding calculation limits
Calculation limits are applied by the Solana network as a method of preventing excessive computing load and maintenance of stability. These limits can be set in the “Solana :: Runtime :: Limits” module, which provides access to various configuration options to optimize performance.
Increasing the calculation limits from Solana :: Runtime :: Limits'
To increase the calculation limit in Devnet, you need to modify the "Solana :: Runtime :: Limits" object. Here is an example of how to do it in rust:
Rust
Use Solana_program :: {
Conct_info :: {next_account_info, conctinfo},
entrance point,
ENTENTPOINT :: Programsult,
Pubkey :: Pubkey,
};
Use solar_sdk :: {
Conct_info :: {Conccountmeta, programmerror},
Pubkey :: Pubkey,
};
ENTENTPOINT! (process_instruborn);
FN process_instruct process (
program_id: & pubkey,
Accounts: I [bills],
Instructions_data: & [U8],
) -> programresult {
// Get the current calculation limit
Let the limits = Solana :: Runtime :: Limits (). compute_limit ();
// Increase the calculation limit
Let New_Limits = Limits :: New (Limits, 10_000); // Set a new limit to 10 GB
// update the limit object with a new value
Let Mut New_Limits_Set = New_Limits.clone ();
new_limits_set.set_comput_limit (10_000);
// Create a account structure for updated limits
Let Limits_account_info: Conccountmeta
and limits,
"Limits",
Programmerror :: Invalidarment,
)?
// update the program limits with new values
If! update_limits (& limits_account_info, new_limits_set.clone ()) {
Return ERR (programmerror :: Invalidarument);
}
OK (())
}
In this example, we create the “Limit” object and then update it to set a new calculation limit of 10 GB. We also include errors handling to make sure the update has been successful.
Configuring calculation limits
To configure the calculation limits for the Solana Devnet account or portfolio, you can modify the following configuration options:
Compute_Limit: Set the maximum calculation time in seconds.
Max_Computations_per_second: limits the number of calculations per second.
Max_operations_per_account: limits the number of operations (e.g. transactions) that can be performed on one account.
More information on these configuration options can be found in the Solana documentation.
The best practices for optimizing the use of memory
To further optimize the use of memory in Devnet, consider the following best practices:
- Use ‘Solana :: Runtime :: Limits’ to manage computing limits.
- Minimize data series.
- Optimize memory allocation using efficient data structures (e.g. tables).
- Avoid exaggerating memory using unnecessary data.
By implementing these strategies, you can effectively optimize the use of memory on the Solana Devnet account or wallet, ensuring efficient performance and scalability of your applications.
