QPR ProcessAnalyzer System Requirements

System Requirements for Web Browsers

One of the following web browsers are needed:

• Windows desktop
  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
• Mac desktop with Safari
• Tablets and smartphones
  • Apple iPad and iPhone with iOS 16 and Safari
  • Android version 9 or higher with Chrome for Android

Note: Due to the rapid update schedule of web browsers, QPR Software does not specify the supported versions but indicates the latest versions that are tested and verified to work. Chrome and Firefox versions newer than the tested versions are likely to work, but QPR Software cannot guarantee their functionality before the next release. Any compatibility issues will be fixed as soon as possible for the next release.

System requirements for QPR ProcessAnalyzer Server

• Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019 or Windows Server version 20H2
• Microsoft SQL Server 2014, Microsoft SQL Server 2016, Microsoft SQL Server 2017 or Microsoft SQL Server 2019 (with Database Engine)
• Sufficiently powerful enough hardware to run the operating system
• Install Server Roles and Features for Microsoft Internet Information Services (IIS)
• .NET 6 ASP.NET Core Runtime Hosting Bundle (available in https://dotnet.microsoft.com/en-us/download/dotnet/6.0)
• For QPR ProcessAnalyzer 2022.8 and earlier releases only: .NET Desktop Runtime (available in https://dotnet.microsoft.com/en-us/download/dotnet/6.0)
• Databases:
  • Microsoft SQL Server 2014, Microsoft SQL Server 2016, Microsoft SQL Server 2017 or Microsoft SQL Server 2019 (with Database Engine)
  • Three databases are required: metadata database, datatables database, and scripting database (more information)

System Requirements for QPR ScriptLauncher

• Microsoft Windows 10, Windows 11 or Windows Server (supported by QPR ProcessAnalyzer Server).
• Internet connection
• To import data from SAP, the sapnco.dll and sapnco_utils.dll files are needed that are part of SAP Connector for Microsoft .NET Version 3.0 (available in SAP Support Portal in https://support.sap.com/en/product/connectors/msnet.html). See instructions for installation.
• .NET 6 Desktop Runtime (available in https://dotnet.microsoft.com/en-us/download/dotnet/6.0)

System Requirements for QPR TaskRecorder

• Operating systems: Windows 10 or Windows 11
• Installation uses approximately 100MB of disk space, and additional of 200MB should be reserved for task recordings.
• Approximately 200MB of memory is used by QPR TaskRecorder.
• QPR TaskRecorder is a .NET 6 application released as a self-contained package, and .NET 6 doesn't need to be installed separately.

Recommended Hardware for QPR ProcessAnalyzer Server (Snowflake)

When running QPR ProcessAnalyzer in Snowflake, there are following requirements to QPR ProcessAnalyzer Server:

• Up to 5 simultaneous users
  • 16GB memory
  • 4 processor cores
• More than 5 simultaneous users
  • 32GB memory
  • 8 processor cores

Dataset sizes don't affect the QPR ProcessAnalyzer Server requirements, because data is processed in Snowflake.

Recommended Snowflake Warehouses

The virtual warehouse sizing in Snowflake follows these general guidelines:

• Scaling up: The more there is data in the process mining model, the larger warehouse size is needed (XS, S, M, L, XL).
• Scaling out: The more there are simultaneous users or the more there are charts and analyses in the dashboard, the more clusters are needed for in the multi-cluster warehouse.

Typical Snowflake warehouses for different model sizes:

• Models up to 10M events: 1 node (XS)
• Models up to 30M events: 2 nodes (S)
• Models up to 100M events: 4 nodes (M)
• Models up to 300M events: 8 nodes (L)
• Models up to 1B events: 16 nodes (XL)

Typical multi-cluster configurations:

• Up to 2 simultaneous users: 1 cluster
• Up to 4 simultaneous users: 2 clusters
• Up to 7 simultaneous users: 3 clusters
• Up to 10 simultaneous users: 4 clusters
• Up to 20 simultaneous users: 5 clusters

It's possible to set Snowflake to adjust automatically the number of clusters based on the load, which is the recommended configuration. There are two scaling policies available and of them the standard scaling policy is suitable for QPR ProcessAnalyzer analytics usage.

• More information about multi-cluster warehouses: https://docs.snowflake.com/en/user-guide/warehouses-multicluster.html.

Recommended Hardware for QPR ProcessAnalyzer Server (in-memory)

• Small datasets (up to 5 million events per model) with simultaneous users
  • 32GB memory
  • 4 processor cores
  • 50GB disk
• Medium datasets (10-20 million events per model) with simultaneous users
  • 64GB memory
  • 8 processor cores
  • 100GB disk
• Large datasets (20-80 million events per model) with simultaneous users
  • 256GB memory
  • 16 processor cores
  • 150GB disk
• Very large datasets (more than 80 million events per model) with simultaneous users
  • 512GB memory
  • 32 processor cores
  • 200GB disk

Recommended Hardware for QPR ProcessAnalyzer Database Server

There are two databases used by QPR ProcessAnalyzer: metadata database and datatables database. The metadata database has relative small amount of data, so pretty lightweight SQL Server is sufficient (for small installations, 4GB memory and 2 processor cores, and heavy usage environments, 8GB memory and 4 processor cores). The datatables database has similar requirements, but in addition the required disk space depends on amount of data stored (100GB - 10TB SSD disk).
